This is a quick demonstration about the main functionality of VIM editor from a JTAC standpoint. This document provide a lot of text “screenshot” to demonstrate what the editor looks like when used in different scenarios. This document does not provide much (or ‘enough’) details about the basic usage (e.g. how to go to command line mode) - the author assume that the audiences already know the basic part of it. For the real beginners, the vimtutor command line tool that comes with VIM is a great learning tool to start with.
overview
[vim is a great tool. Tools are always good to have - great tools are
seemingly productivity booster. However, I do see real experts who rely only on
notepad and a dos telnet windows to get their work well done, while others had
poor performance on top of super cool tools — It seems to me that tools “MAY”
help, but to what extent that really depends :)]
-
feature rich
-
it’s very rare that one job can be done only in other text editors but not in VIM. On the other hand, VIM has a lot of UNIQUE features that all other editors may NOT have
[although this is almost true, it is only based on experience of the authors. In theory, although the chances are slim, it is still possible that there exists a 3rd editor ("that 2nd editor" should be vi’s good company: emacs) that brings a new feature currently not yet supported by the two]
.
-
-
portability
-
available in all major platforms
-
*nix, MAC, Win , BSD, ipad/iphone/android, etc
[again per my own experiences, I’ll rate linux/unix-like version the top, then macOS version. Windows version are as good as in other OS versions feature-wise, but not as "nature" as unix/mac version (just think about its strange C:\ file system notation…) personally I prefer to stick to vim-over- cygwin whenever I have to work on a windows vim]
-
-
"modal" editing, keyboard oriented
[believe it or not, keyboard IS more efficient , but that efficiency only comes after you (sometimes intentionally) stick to it to train your "muscle memory" and finally get used to it - meaning that you are actually doing the editing work (copy/paste/delete/indentation/etc) while your brain don’t even know how those are done. It may sound funny but it’s really the fact that ,sometime, when being asked "what did you type to …?", you have to really think of it to figure out what you just typed in :D . Anyway mouse might still be faster/easier for most people who don’t want to spend(or waste) time on keyboard]
-
insert/normal/visual/replace/commandline/… mode
-
EVERYTHING can be done efficiently with keyboard
-
-
highly program(script)-able, customizable, flexible, extensible
-
easily compose new operator/operations per your own demand
-
vimL: programming language:
[vim Language, built-in ability to combine vim command together to make a script. personally I think vimL is the essential/unique power of vim comparing with other editors]
-
Here is a good article introducing VIM for its "20 years anniversary" :
1. vim as an text editor
1.1. editor(e.g: notepad, ULTRAEDIT)
-
Vim has 6 basic modes and 6 additional modes.
-
4 of them are most commonly used
-
insert
like windows notepad, whatever you typed in will be inserted as file content
appended in this document are some of the frequently used
[this really depends on your personal favorite/habit - since there are always multiple ways to do the same thing in vim, different person might have quite different “musal memories”]
insert-mode commands -
normal mode
in normal mode, keystrokes become "commands" instead of the file content. The result will be navigation and manipulation of text.
appended in this document are some of the frequently used normal-mode commands
-
visual mode
visually select text in characters-wise, line-wise, or block-wise For navigation and manipulation of text selections, this mode allows you to perform most normal commands, and a few extra commands, on selected text.
some of the frequently used visual-mode commands
-
command-line mode
in this mode the cursor will jump into the bottom of the editor, and type in vim command
-

vimtutor - a (very intuitive) program to learn vim program:
-
vimtutor: a shell command to teach you how to use vim
vimtutor=============================================================================== = W e l c o m e t o t h e V I M T u t o r - Version 1.7 = =============================================================================== Vim is a very powerful editor that has many commands, too many to explain in a tutor such as this. This tutor is designed to describe enough of the commands that you will be able to easily use Vim as an all-purpose editor. The approximate time required to complete the tutor is 25-30 minutes, depending upon how much time is spent with experimentation. ATTENTION: The commands in the lessons will modify the text. Make a copy of this file to practise on (if you started "vimtutor" this is already a copy). It is important to remember that this tutor is set up to teach by use. That means that you need to execute the commands to learn them properly. If you only read the text, you will forget the commands! Now, make sure that your Shift-Lock key is NOT depressed and press the j key enough times to move the cursor so that Lesson 1.1 completely fills the screen. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Lesson 1.1: MOVING THE CURSOR ** To move the cursor, press the h,j,k,l keys as indicated. ** ^ k Hint: The h key is at the left and moves left. < h l > The l key is at the right and moves right. j The j key looks like a down arrow. v 1. Move the cursor around the screen until you are comfortable. 2. Hold down the down key (j) until it repeats. Now you know how to move to the next lesson. 3. Using the down key, move to Lesson 1.2. NOTE: If you are ever unsure about something you typed, press <ESC> to place you in Normal mode. Then retype the command you wanted. NOTE: The cursor keys should also work. But using hjkl you will be able to move around much faster, once you get used to it. Really! "/tmp/tutorunYxYO" 970 lines, 33256 characters

1.2. search with more weapons
-
regex(regular expression or "pattern"):
-
search for portion of data that we care most
-
-
range:
-
A range permits a command to be applied to a group of lines
-
:[RANGE]COMMANDS, while [RANGE] can be any of the following (and more)
-
many way to define a range:
-
visual select
[this is done by press v,V or ctrl-v from normal mode, then move the cursor by motion keys(e.g, h,l,j,k). Pressing ‘:’ after that will bring (nicely) your cursor into the bottom command line area with the visual selection range marks :'<,'> that you can start your command with.]
delete(COMMANDS) visual selected texts([RANGE]):'<,'>delete
-
mark
[this is done by pressing mN, where N is a letter a to z, to generate a mark, say mark ‘a’, to mark a position for later use]
search for keyword ‘abc’(COMMANDS) from mark ‘a’ to mark ‘b’ ([RANGE]):'a,'bg/abc/
-
line numbers
indent from line 1 to line 20:1,20>
-
search back and forth
search for “abc”, but only from last occurrence of ‘`#show '’ to the next occurrence of it:?#show ?,/#show /g/abc/
-
-
-
global: search and perform other useful actions:
-
default action on search is "jump to the matches" (to have a look)
-
there can be other actions triggered on (a) match(es)
[this is extremely powerful — ANY vim command can act on the matched texts, see :help global]
-
replace(substitution),
-
print,
-
delete,
-
copy(‘yank’ in vi/vim term),
-
sort
-
etc
-
-
vim :global command syntax
search for “matches”:[RANGE]g[lobal]/{pattern}/[cmd]
search for “non-matches”:[RANGE]v[global]/{pattern}/[cmd]
-
how it works
The global commands work by first scanning through the [range] lines and marking each line where a match occurs (for a multi-line pattern, only the start of the match matters). In a second scan the [cmd] is executed for each marked line with its line number prepended. For ":v" and ":g!" the command is executed for each not marked line. If a line is deleted its mark disappears.
— :help global
-
1.3. search example: regex (JTAC may like)
[this is useful for the device log syntax folding that will be demonstrated in later sections, which requires using regex to recognize each command line and its output]
/^\(\S\S\+[^ <(]\{0,37}\S[#>%$]\s*\S\+\|slot \d\d\=->\S\+\|->.\+\|\*-\*-\*-\*-\*-\)/
[just for the demonstration purpose - it doesn’t really work in practice]
broken into the
following lines:
/
^\( 
\S\S\+[^ <(]\{0,37}\S[#>%$]\s*\S\+
\| 
slot \d\d\=->\S\+
\|
->.\+
\|
\*-\*-\*-\*-\*-
\)
/
 | starting with |
 | logical OR |
-
must contain at least one of following as a PS var
[Prompt String Variable]
:'#' : cisco,juniper...priviledge mode, unix root '>' : cisco,juniper...exec mode,some unix shell '%' or '$' : some unix shell prompt '->' : junos-e vxworks shell '*-*-*-*-*-' : junos-e show-tech
-
and ,
-
for PS #,> or %:
-
at least 2 charactors before #,e.g.: this will be matched: R1blabla while this won’t(normally hostname has two or more charactors): Rblabla
-
leading spaces are ok in CMD : R1# blabla
-
no space preceding # : R1 #blabla (will not match)
-
must has at least 2 non-blank chars in beginning of the line, and
-
must NOT contain any of following chars before the PS var,
: blank < : a literal '<' charactor ( : a literal '(' charactor ] : a literal ']' charactor -
must has no more than 40 chars in total before a # or > or % char, and
-
must has at least 1 non-blank (space, tab) charactor as a command
-
-
or , for PS ‘->’ (junoe "shell" mode): different flavors are supported
-
this can be the ERX LM line card shell mode
slot NN->CMD
where N can be 1 or 2 digits (e.g. LM line card number),
-
this can be ERX LM serial shell mode
->CMD
where CMD can be 1 (like an t, means task) or more CHs ,
-
this can be the ERX SRP shell mode ,w/ a preceding space,
-> CMD
-
-
or , for ‘*-*-*-*-*-’
-
no any other contition modifier (there must be no other charactors),
-
this is simply ERX tech-support command delimitor
-
-
-
overall, basically it matches a command line in logs generated by:
-
JUNOS based products (M/T/MX)
-
JUNOSe(ERX/E320)
-
CISCO
-
UNIX/LINUX
-
any other devices that use # , > or % as a prompt (can be changed per demand)
-
1.4. search example: global
sometime one single CLI print long long outputs(600+ lines) you need a way to collect only some lines based on a desired criterials. for example in the following long (600+ lines) outputs of a ‘show’ command:
1 NWRKNJ-VFTTP-138:vol#show ip int lag OLT01.2570039
2 lag OLT01.2570039 line protocol VlanSub is up, ip is up
...<snipped>...
42 IP policy input jnpr-VIDEO:ONLY
43 classifier-group dhcp entry 1
44 0 packets, 0 bytes
45 rate-limit-profile dhcplimit
46 committed rate: 1280 bps, committed burst: 8192 bytes
47 excess burst: 0 bytes
48 committed: 0 packets, 0 bytes, action: transmit
49 conformed: 0 packets, 0 bytes, action: drop
50 exceeded: 0 packets, 0 bytes, action: drop
51 classifier-group jnpr-VIDEO-TRAFFIC entry 1
...<snipped>...
62 classifier-group jnpr-VIDEO-TRAFFIC entry 2
...<snipped>...
535 classifier-group jnpr-VIDEO-TRAFFIC entry 45
...<snipped>...
644 Dropped exceeded packets 0, bytes 0
645
647 NWRKNJ-VFTTP-138:vol#
In a lot of cases, most ACL entries are with only zero packet count , and the troubleshooting need to be focused on those entries with non zero values. So, the issue here becomes: how to only display those ACL entries that with NON ZERO counters in the line that follows the ACL entry index, while ignoring those entries that with only zero as counters?
[visual-select]
-
regex
:'<,'>g/classifier-group.*\n\s*[1-9]\d* packets/
result:found 3 ACL entries (out of 50+) with non-zero counters in the very next line:'<,'>g/classifier-group.*\n\s*[1-9]\d* packets/ 44 classifier-group dhcp entry 1 525 classifier-group VIDEO-TRAFFIC entry 44 536 classifier-group DNS-TRAFFIC entry 1
-
regex
:'<,'>g/classifier-group.*\n\s*[1-9]\d* packets/.,+1p
result:ACL entries along with following non-zero value counters:'<,'>g/classifier-group.*\n\s*[1-9]\d* packets/.,+1p 44 classifier-group dhcp entry 1 45 1 packets, 378 bytes 525 classifier-group VIDEO-TRAFFIC entry 44 526 84 packets, 12665 bytes 536 classifier-group DNS-TRAFFIC entry 1 537 2 packets, 226 bytes
-
a short version
"empty" pattern will call the _previous applied pattern: really handy!:g// :g//.,+1p
1.5. search example: global with range (good for large files)
:?#show ?,$g/classifier-group.*\n\s*[0-9]\d* packets/.,+1p
[just-for-demonstration]
into the following lines:
:$
g/classifier-group.*\n\s*[0-9]\d* packets/
.
,
+1
p
| go to command mode |
| starting from a position as the start of the searching range, which is the first match of pattern `#show ` when search backward from current cursor place, |
 | to |
 | the next position as the end of the searching range, which is the end of the whole file |
 | and in this range perform the global (search) command. |
 | Now whenever getting a match, do some range-based job (see note 9) starting right from the current (.) matching line |
 | till |
 | the next line following the matched pattern |
 | and the job is to print it (here to display, not hard-print to printer) |
:?#show ?,/#show /g/classifier-group.*\n\s*[0-9]\d* packets/.,+1p
1.6. search example: spanning files
there are many ways to search across files/folders. Here are 2 way that is commonly used:
-
use vim’s built-in grep: vimgrep
search "show resources" or "fail", case insensitive, in all log files under folder ./logs, recursively; jump to it once got the first finding
[this will invoke the quickfix feature that will be shown below]:vimgrep /show resources\c\|fail\c/j ./logs/**/*.log
-
use external grep tool
use external grep tool
[just to demonstrate the usage here, not necessarily recommended in practice]grep! -R "show resources|errors" ./logs/**
or , another way to call external grep:!grep -R "errors" ./logs/**
-
“quickfix” window
Vim has a special mode to speedup the edit-compile-edit cycle. This is inspired by the quickfix option of the Manx’s Aztec C compiler on the Amiga. The idea is to save the error messages from the compiler in a file and use Vim to jump to the errors one by one. You can examine each problem and fix it, without having to remember all the error messages.
— :help quickfixbut in practice, regardless of code developing, “quickfix” window can also be used to quickly locate the target matching result.
invoking the quickfix window after the vimgrep search:cw or :copen
for more info::help quickfix
| the quick fix window, invoked by :cw, listing all matched lines from all files containing the pattern |
| put the cursor in a line in the quickfix window, press <enter>, the corresponding file containing current found match will be opened in another window |
| the new opened window , with the matched line(s) displayed |
| the matched line in the opened file |
1.7. window split
[vim’s (tab)auto-completion system is as fantastic as its other features, you can use pretty much the similiar way to complete a command as if when you are typing a command in a modern linux bash , or a cisco router]

1.9. MUCH MORE great features as an editor
There are MUCH MORE features that VIM is doing better than other editors. It’s
not possible to demonstrate all well-known features in one document
[not even in
one (say, 400 pages) book]
. I’ll demonstrate some of them selectively in the
later sections.
-
external tool integration
-
folding
-
advanced undo system: (time machine)
-
undo over branch,
-
permanent undo over close
-
-
diff & patch
-
multi-page(MPage)
-
text hyper links(utl)
-
math
-
column/block editing(c-v)
-
alignment(Align)
-
write/append selected texts into other files
-
multiple clipboard (register)…
-
syntax highlighting (customizable)
-
colorscheme can be easily changed to your favorite
-
default and koehler is my favorite
-
-
user defined command (command)
-
event triggered action (autocmd)
-
platform independent Chinese input system (vimim)
-
…
-
encryption
you can encrypt your file , open it with a password, work on it, then save it still in the encrypted from.
2. external tools integration (JTAC may like)
-
JTAC help customer to troubleshooting the outage
-
to troubleshoot JTAC need log(files)
-
good tools can help
-
notepad is too slight handling large files …
[notepad is still a good note pad, even though MS-word/office are dominating today]
-
less is not that less, it is actually a very feature-rich,faster and agile tool
[one of the best (my favorite) text ‘viewer’/or ‘pager’]
-
more is not that more - it’s actually no much use
-
most is not yet recognized by the most yet
-
grep good/bad info out of raw log
-
sort to make log entries in (wanted) order
-
uniq to remove redundant entries
-
cut good info out of raw entries
-
ed/sed/awk is useful for pipelines/oneliner lovers or scripting
-
diff old&new files and then patch the old into new one
-
…
-
how to only search a specific portion of a file (range)?
a log file may contain over 200 command captures, 30k+ lines, so what if we only want to search in the output of "show system log" command?
you can copy a portion of the file & save to a temporary file with a dummy name for your grep to run on, but this is not convenient and sometimes boring if you have to repeat over again and again. -
you have to blindly type in the keyword you want to search
use grep with pipe in terminal is handy,but blindly typing the long keyword/pattern from terminal without reading them in the screen when you are typing is sometime pain/error-prone.
e.g you have to remember(or write down, copy & paste) this long stupid-looking command that you want to search in a log file, before you can type them in the terminal:print__11Ic1Detector -
it will add more pain and inconvenience in the case that you are not quite sure about what keyword you should search with — preferablely if you can do some real-time quick search when you are reading through the log file , and very often you will have to refine the pattern and repeat the above whole process over.
-
integrates all(most) equivalent functions of these tools
-
provides a universal interface to for external utilities
-
use legendary *nix tool in a new/more nature way, from inside vim
-
all CLI based apps,supporting stdin/stdout steams, including you own APPs, can be re-used
-
that’s why "text stream"(pipes) is part of essential UNIX philosophy
-
-
you can do following in almost real time and a much intuitive way:
-
search with a pattern
-
get search result
-
start a new search based on the search result (‘search out of search result’)
-
undo the search (steps back to where we were)
-
redo a search (steps forward to the previous search result)
-
refine the new search pattern
-
repeat the whole process

2.1. external tool example: ‘grep’ from inside vim
2.1.1. quick review of grep
grep is a utility for searching plain-text data sets for lines matching a regular expression. Its name comes from the old ed command g/re/p (global / regular expression / print) grep is versatile tool with full feature regex support, here we list several of the simplest and most common usage cases just in order to demonstrate how to use external tools from within vim.
following are some quick examples, each paired with an equivalent vim command that calls external grep command directly but from within VIM editor
-
get useful info
cat FILE | grep -i "what-i-want" :RANGE!grep -i "what-i-want"
-
trash garbage info
cat FILE | grep -v "what-i-don't-need" :RANGE!grep -v "what-i-don't-need"
-
logical ‘OR’
cat FILE | grep -E "want-this|or-that" :RANGE!grep -E "want-this|or-that"
-
"search out of search results", recursively
[This is one of the many places that vim can get work done better than traditional way - you can look at the text in the vim editor while thinking of what can be the next good pattern/keyword for the next grep , and see the grep result right away in the same editor. This is indeed much better than the traditional way that you each time have to check the grep result by redirecting it either to a temp file so you can open with another editor, or to a text pager/viewer (like ‘more’ or ‘less’), then quit the file or text pager, refine your grep and repeat the whole thing all over.]
Example 8. find lines about bgp related info, generated 8/16/2012, and containing keyword "peer reset"“traditional” waycat FILE.log | grep "bgp" | grep "8/16/2012" | grep "peer reset"
vim way:RANGE!grep "bgp" | grep "8/16/2012" | grep "peer reset"
-
repeat the refining process right on grep result,which you are visually seeing in the editor
— this is a really powerful but still convenient method to approach a complex target -
never need to leave/exit editor to use external tools from another terminal!
2.1.2. grep example: "increamental multi-steps search"(or, "search out of search result")
To make it simple, you can always just use the simplest grep, do it multiple times , each time with a new pattern, to gradually narrow down the target logs entries. Or, for "power" grep user, you compacting everything in one line (“one-liner”) is a faster way to get the end result in just one shot.

:'<,'>!grep -iE "08\/07.* 0[5-6]:(.*bgp.*code 54|link|warn|error|fail)"
2.1.3. more grep example
some old devices need help from grep,since there is no other fancy options a/v
from the original dir command
[even MS-dos support some of the sort options to some extent for their

2.3. external tool example: reuse your own programs/scripts
if you have some of your own well-tested programes/scripts and enjoyed using
them in the terminal, you can always re-use them from inside vim. The even
better thing is that the result will be displayed “on the fly”.
[This is more efficient than relying on traditional method that you
have to switch between your editor and terminals, and quite often you’ll need to
copy/paste between your work file and some temp files/etc. However, for better
integration with VIM, your script/program better support stdin/stdout “text
streams” as input/output flow, otherwise you might have to wrap them into that
looking :)]

| call the external "showversion" program, and apply the selected range of text as the stdin to the program |
| because the every line of “show version” output (line26-line62,total 36) was processed by the external program and was replaced by the result |
|
|
the “showversion” program is written by Jonathan with the original name: “realTimeGetterAllFromShowVersion”. Here we use it to domonstrate how to re-use the existing program that you took time to write/test, from within vim. so your/others effort/hard work won’t be wasted. |

better than nothing
-

-
no need modify(good)
-
disadvantage: Do not persist across file reload

-
good for well-indented text (code in consistent indent style, or JUNOS config)
-
advantage: no need modify file content

-
Markers in the text tell where folds start and end.
-
This allows you to precisely specify the folds.

really powerful, but takes time and sharp learning curve to make it work

3.3. folding: indentation: JUNOSe/CISCO config file
[personally I prefer folding on mark than indentation in this case. Mark folding looks more ‘compact’ and hence ‘cleaner’, because the marker method includes the the ‘headers’ (e.g, ‘groups’) line while indentation method only folds the indented lines, excluding the headers]

3.5. folding: syntax: JUNOS logs
[6 vs. 6000 lines, the ratio depends on how long output the command line printed. in this case a ‘show config’ prints thousands of lines. actually to achive this effect, the long regex demonstrated earlier as an example was used to locate the command line itself as part of the work; folding on ‘syntax’ was created in a ‘syntax file’; and the syntax folding action was triggered on a ‘set filetype’ event, which, was either triggered by a manual vim ex command, or the vim automatic file type detection method …]

4. vim as file browser/manager: netrw (windows explorer)
-
folder operation
-
files operation:cp,mv,delete
-
jumping back and forth
-
going up and down
-
bookmarks/browsing history
-
open files with associated applications: pdf, word, png, rmvb, etc.
-
etc
In VIM this is essentially done by the netrw plugin, which is now one of the VIM built-in plugins - it comes with VIM so no need to install the plugin anymore.
This plugin don’t need to be activated - it will just work by default.
4.1. advantage of vim as a file manager
-
search file/folders fast
-
the same skill you learned about how to search text in a file!
-
all regex applys!
-
-
open/edit remote files/dirs directly from local machine (JTAC,JUNOS)
-
traditional way:
-
copy(download) remote file to local machine
(plus: ftp,http,scp,sftp,etc tools need to be explicitly involves) -
open/edit local copy, save to a local temp file
-
copy(upload) to remote place (ftp,http,scp,sftp tools involves)
-
-
with VIM:
-
open/edit remote file directly, save, done
[some may think this is not too much fancy in unix system - all unix-like system comes with a standard vi/vim installed. However, Think about how do you modify files in a remote system that supports SSH, but no fancy terminal-based editor installed- for example, you may want to edit some files in your iphone :p ]
-
-
-
open edit file from achives directly
-
traditional way:
-
extract to another temp folder
-
open/edit files from the temp folder, save
-
make a new achive
-
-
with VIM:
-
open/edit files from archieve , save, done
-

5. vim as terminal emulator: Conqterm (secureCRT) (JTAC may like)
This is done by vim Conque Shell plugin. Once installed, it can be activated to start a bash terminal into a VIM buffer.
:ConqueTerm bash
5.1. Conqterm examples

| line number |
| router (ERX) command line typed in |
| router (ERX) command line output captures |
| snipped - original output is long |
| vim "insert mode" indicator - we ARE in an editor, no doubt! |
5.2. terminal emulator:list of cool features
-
pattern search ,jumping using same skills as if in normal text file
-
syntax highlight
-
(syntax) fold
-
multi-tab (like secureCRT)
-
split, multi page, etc
-
suspend/resume anytime as will
-
save logs
-
etc…
6. vim as free hand drawing tool: drawit (paint,visio,word)(JTAC may like)
6.1. free hand tools considerations
-
JTAC sometimes need draw ascii graph:
-
network topology (mostly)
-
flow chart (occasionally)
-
-
available tools overview:
-
notepad is only good at horizontal lines, try it with vertical lines
-
paint is lightweight, but … anyone use that?
-
word/visio is standard/powerful/… but heavy & expensive
-
heavy in the sense like "overkills" for simple tasks
-
expensive not in sense of price, more in sense of time
-
UltraEdit and others might be nice, but try it with a MPLSVPN topo
-
-
ascii art vs. binary tools:
-
ascii art is always my first choice whenever possible:
-
small/portable/easy to maintain,
-
still cool/good enough to demonstrate the issue
-
-
small: only several K or within a hundred of Bytes
-
clear: arrow, signs, letters,numbers are always enough to demonstrate
-
portable: 100% green, no need to install any fancy software
-
maintain: the cool thing is you can just write topology directly into configs/code!
-
There are a couple of plugins available to draw ascii-arts, my personal favorite is drawit.
6.2. example:draw a "decent-looking" MPLS-VPN topology, in 2 minutes
[I finished it in this vim presentation within 1.5 min I guess :) ]
-
4 P backbone
-
2 PE
-
2 CE
-
lines/marks/rectangle/eclipse (for better readability)

Multi-level IS-IS, Areas 0001 and 0002 with ISO NET based on router number. lo0 address of r3 and r4 not injected into Area 0001 to ensure optimal forwarding between 10.0.3.3 and 10.0.3.4. Passive setting on r5’s core interfaces for optimal Area 0002-to-core routing. No authentication or route summarization. Routing policy at r5 to leak L1 externals (DC routes) to L2. Redistribution of static default route to data center from both r6 and r7. Redistribution of 192.168.0/24 through 192.168.3/24 routes from RIP into IS-IS by both r6 and r7. All adjacencies are up, reachability problem discovered at r1 and r2 caused by local aggregate definition. Corrected through IBGP policy to effect 10.0/16 route advertisement from r3 and r4 to r1 and r2; removed local aggregate from r1 and r2. Suboptimal routing detected at the data center and at r1/r2 for some locations. This is the result of random nexthop choice for data center’s default, and the result of r1 and r2’s preference for r3’s RID over r4 with regard to the 10.0/16 route. This is considered normal behavior, so no corrective actions are taken. |

VIM(1) VIM(1)
NAME
vim - Vi IMproved, a programmers text editor
SYNOPSIS
vim [options] [file ..]
vim [options] -
vim [options] -t tag
vim [options] -q [errorfile]
ex
view
gvim gview evim eview
rvim rview rgvim rgview
DESCRIPTION
Vim is a text editor that is upwards compatible to Vi. It can be used to edit all kinds of plain text. It is especially useful for editing programs.
There are a lot of enhancements above Vi: multi level undo, multi windows and buffers, syntax highlighting, command line editing, filename completion, on-line help, visual selection, etc..
See ":help vi_diff.txt" for a summary of the differences between Vim and Vi.
While running Vim a lot of help can be obtained from the on-line help system, with the ":help" command. See the ON-LINE HELP section below.
Most often Vim is started to edit a single file with the command
vim file
......
Script to detect the type of a file by its contents. See ":help 'filetype'".
/usr/share/vim/vim73/print/*.ps
Files used for PostScript printing.
For recent info read the VIM home page:
<URL:http://www.vim.org/>
SEE ALSO
vimtutor(1)
move cursor on top of any places in the “vimtutor” command under the man page “SEE ALSO” section, and press ctrl-], vim will take you to the man page of that new command under current cursor. a ctrl-o will jump back to ‘man vim’ again.

7
8 SYNOPSIS
9 vimtutor [-g] [language]
10
11 DESCRIPTION
12 Vimtutor starts the Vim tutor. It copies the tutor file first, so that it can be modified without changing the original file.
13
14 The Vimtutor is useful for people that want to learn their first Vim commands.
15
16 The optional argument -g starts vimtutor with gvim rather than vim, if the GUI version of vim is available, or falls back to Vim if gvim is not found.
17
18 The optional [language] argument is the two-letter name of a language, like "it" or "es". If the [language] argument is missing, the language of the current locale will be used. If a
19 tutor in this language is available, it will be used. Otherwise the English version will be used.
20
21 Vim is always started in Vi compatible mode.
22
23 FILES
24 /usr/share/vim/vim73/tutor/tutor[.language]
25 The Vimtutor text file(s).
26
27 /usr/share/vim/vim73/tutor/tutor.vim
28 The Vim script used to copy the Vimtutor text file.
29
30 AUTHOR
31 The Vimtutor was originally written for Vi by Michael C. Pierce and Robert K. Ware, Colorado School of Mines using ideas supplied by Charles Smith, Colorado State University. E-mail:
32 bware@mines.colorado.edu.
33 It was modified for Vim by Bram Moolenaar. For the names of the translators see the tutor files.

9. vim programming language: vimL
-
vim is programmable - vimL programming language
-
combine all existing command/operations into action sequence
9.1. vimL example:clean a log file
-
remove special control characters
[e.g, ascii code 8 or 9,representing BS (Backspace) or HT(Horizontal Tab), see unix man page man ascii for more detail]
-
‘CR’ (unix version of return)
-
-
"translate" control characters back into the control
-
turn the “backspace” in the log into "deleting 1 characters before it"
Example 24. vimLcommand! Log2AsciidocClean call Log2AsciidocClean() function! Log2AsciidocClean() "clean the file "remove some special CH, like ^M :%s#\r\|\s\=\(^G\|^M\)##
endfuncAlthough the “special” characters listed visually (represented by a literal ^ and G) in this example does not looks “special”, they are printed here only for the visibility purpose. The character itself (e.g. you pressed a BACKSPACE key) is not visible in the real file. In vim there is a way to generate this kind of non-visible character: by pressing a “ctrl-V” (make it Visual) and another “ctrl-M”, a “Backspace”,repsensented in the text as a ^M (ascii code 0x07) is inserted. A ^M (\r) can be generated the same way. execute new created command:Log2AsciidocClean

-
turn a huge log file into a structured HTML file
-
you can then share the web link instead of bothering attachment/go to a server/passwd/etc..
-
all can be done with a few keystrokes in a second!
end of the command output
[there is a longer story behind this. Following code was partially captured from a sequence of code groups that each will fulfill a partial work to proceed one step toward my target: turning a pure text log file to the source of a structured HTML file. One handy feature of the generated HTML will be the presence of “go back to TOC” label following each command line, which is done by inserting a “<<top>>” mark right after each command line (done by a vim substitution regex).]

endwhile
endfunc
with the above vimL code, a long text log file can be converted to a
not-so-bad-looking web page, with a Table Of Content linking to each of the
command executed.
[with my current VIM script(I may change/enhance it from time to time),
I type following newly created vim command to get the job done:
:Log2AsciidocClean
:Log2AsciidocTop
:Log2AsciidocIndent
:Log2AsciidocList
:Asciidoc2Html
each of the above “user command” do one different job in the processing flow.
These can be further simplified into one VIM user command like:
:Log2Asciidoc
But personally I prefer to disassemble it to different processing stage, so I can review
the partial result just in case something went wrong.

-
integration into/with other apps(mutt,w3m,firefox,etc)
-
document preparation system (integration of asciidoc, aafigure, markdown, etc)
-
taking notes, blogging(vimpress), GTD tool
-

10.7. become a “vimer”
VIM looks hard for a beginner, especially for those who always prefer GUI based editors that are easily available around. The biggest headache is that there are a lot of "command" to remember before you can even proceed with your editing work. However, the power is also generated from the same and, Once you get use to it, you will wonder how you ever got along without it!
10.8. vim , unix philosophy, learning curve, etc
-
UNIX philosophy
Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.
Doug McIlroy
— inventor of Unix pipes -
editor learning curve
[the “curve” itself,however,is quite confusing and controversial]
-
editor war/jokes
[mostly between vi vs. emacs users]
10.9. (some) resource lists
-
google: tons of vim document, tips, articles, discussions, …
-
vim help system.Unbelievable good.
-
:help user-manual
-
:help ANYTHING
-
-
An application to help learning vim: vimtutor
The Vimtutor is useful for people that want to learn their first Vim commands.
— man vimtutor -
