12==============================================================================
131. Various commands					*various-cmds*
14
15							*CTRL-L*
16CTRL-L			Clear and redraw the screen.  The redraw may happen
17			later, after processing typeahead.
18
19							*:redr* *:redraw*
20:redr[aw][!]		Redraw the screen right now.  When ! is included it is
21			cleared first.
22			Useful to update the screen halfway executing a script
23			or function.  Also when halfway a mapping and
24			'lazyredraw' is set.
25
26						*:redraws* *:redrawstatus*
27:redraws[tatus][!]	Redraw the status line of the current window.  When !
28			is included all status lines are redrawn.
29			Useful to update the status line(s) when 'statusline'
30			includes an item that doesn't cause automatic
31			updating.
32
33						*:redrawt* *:redrawtabline*
34:redrawt[abline]	Redraw the tabline.  Useful to update the tabline when
35			'tabline' includes an item that doesn't trigger
36			automatic updating.
37
38							*N<Del>*
39<Del>			When entering a number: Remove the last digit.
40			Note: if you like to use <BS> for this, add this
41			mapping to your .vimrc: >
42				:map CTRL-V <BS>   CTRL-V <Del>
43<			See |:fixdel| if your <Del> key does not do what you
44			want.
45
46:as[cii]	or					*ga* *:as* *:ascii*
47ga			Print the ascii value of the character under the
48			cursor in decimal, hexadecimal and octal.
49			Mnemonic: Get Ascii value.
50
51			For example, when the cursor is on a 'R':
52				<R>  82,  Hex 52,  Octal 122 ~
53			When the character is a non-standard ASCII character,
54			but printable according to the 'isprint' option, the
55			non-printable version is also given.
56
57			When the character is larger than 127, the <M-x> form
58			is also printed.  For example:
59				<~A>  <M-^A>  129,  Hex 81,  Octal 201 ~
60				<p>  <|~>  <M-~>  254,  Hex fe,  Octal 376 ~
61			(where <p> is a special character)
62
63			The <Nul> character in a file is stored internally as
64			<NL>, but it will be shown as:
65				<^@>  0,  Hex 00,  Octal 000 ~
66
67			If the character has composing characters these are
68			also shown.  The value of 'maxcombine' doesn't matter.
69
70			If the character can be inserted as a digraph, also
71			output the two characters that can be used to create
72			the character:
73			    <ö> 246, Hex 00f6, Oct 366, Digr o: ~
74			This shows you can type CTRL-K o : to insert ö.
75
76			{not in Vi}
77
78							*g8*
79g8			Print the hex values of the bytes used in the
80			character under the cursor, assuming it is in |UTF-8|
81			encoding.  This also shows composing characters.  The
82			value of 'maxcombine' doesn't matter.
83			Example of a character with two composing characters:
84				e0 b8 81 + e0 b8 b9 + e0 b9 89 ~
85			{not in Vi} {only when compiled with the |+multi_byte|
86			feature}
87
88							*8g8*
898g8			Find an illegal UTF-8 byte sequence at or after the
90			cursor.  This works in two situations:
91			1. when 'encoding' is any 8-bit encoding
92			2. when 'encoding' is "utf-8" and 'fileencoding' is
93			   any 8-bit encoding
94			Thus it can be used when editing a file that was
95			supposed to be UTF-8 but was read as if it is an 8-bit
96			encoding because it contains illegal bytes.
97			Does not wrap around the end of the file.
98			Note that when the cursor is on an illegal byte or the
99			cursor is halfway a multi-byte character the command
100			won't move the cursor.
101			{not in Vi} {only when compiled with the |+multi_byte|
102			feature}
103
104						*:p* *:pr* *:print* *E749*
105:[range]p[rint] [flags]
106			Print [range] lines (default current line).
107			Note: If you are looking for a way to print your text
108			on paper see |:hardcopy|.  In the GUI you can use the
109			File.Print menu entry.
110			See |ex-flags| for [flags].
111			The |:filter| command can be used to only show lines
112			matching a pattern.
113
114:[range]p[rint] {count} [flags]
115			Print {count} lines, starting with [range] (default
116			current line |cmdline-ranges|).
117			See |ex-flags| for [flags].
118
119							*:P* *:Print*
120:[range]P[rint] [count] [flags]
121			Just as ":print".  Was apparently added to Vi for
122			people that keep the shift key pressed too long...
123			Note: A user command can overrule this command.
124			See |ex-flags| for [flags].
125
126							*:l* *:list*
127:[range]l[ist] [count] [flags]
128			Same as :print, but display unprintable characters
129			with '^' and put $ after the line.  This can be
130			further changed with the 'listchars' option.
131			See |ex-flags| for [flags].
132
133							*:nu* *:number*
134:[range]nu[mber] [count] [flags]
135			Same as :print, but precede each line with its line
136			number.  (See also 'highlight' and 'numberwidth'
137			option).
138			See |ex-flags| for [flags].
139
140							*:#*
141:[range]# [count] [flags]
142			synonym for :number.
143
144							*:#!*
145:#!{anything}		Ignored, so that you can start a Vim script with: >
146				#!vim -S
147				echo "this is a Vim script"
148				quit
149<
150							*:z* *E144*
151:{range}z[+-^.=]{count}	Display several lines of text surrounding the line
152			specified with {range}, or around the current line
153			if there is no {range}.  If there is a {count}, that's
154			how many lines you'll see; if there is only one window
155			then twice the value of the 'scroll' option is used,
156			otherwise the current window height minus 3 is used.
157
158			If there is a {count} the 'window' option is set to
159			its value.
160
161			:z can be used either alone or followed by any of
162			several punctuation marks.  These have the following
163			effect:
164
165			mark   first line    last line      new cursor line ~
166			----   ----------    ---------      ------------
167			+      current line  1 scr forward  1 scr forward
168			-      1 scr back    current line   current line
169			^      2 scr back    1 scr back     1 scr back
170			.      1/2 scr back  1/2 scr fwd    1/2 scr fwd
171			=      1/2 scr back  1/2 scr fwd    current line
172
173			Specifying no mark at all is the same as "+".
174			If the mark is "=", a line of dashes is printed
175			around the current line.
176
177:{range}z#[+-^.=]{count}				*:z#*
178			Like ":z", but number the lines.
179			{not in all versions of Vi, not with these arguments}
180
181							*:=*
182:= [flags]		Print the last line number.
183			See |ex-flags| for [flags].
184
185:{range}= [flags]	Prints the last line number in {range}.  For example,
186			this prints the current line number: >
187				:.=
188<			See |ex-flags| for [flags].
189
190:norm[al][!] {commands}					*:norm* *:normal*
191			Execute Normal mode commands {commands}.  This makes
192			it possible to execute Normal mode commands typed on
193			the command-line.  {commands} are executed like they
194			are typed.  For undo all commands are undone together.
195			Execution stops when an error is encountered.
196
197			If the [!] is given, mappings will not be used.
198			Without it, when this command is called from a
199			non-remappable mapping (|:noremap|), the argument can
200			be mapped anyway.
201
202			{commands} should be a complete command.  If
203			{commands} does not finish a command, the last one
204			will be aborted as if <Esc> or <C-C> was typed.
205			This implies that an insert command must be completed
206			(to start Insert mode, see |:startinsert|).  A ":"
207			command must be completed as well.  And you can't use
208			"Q" or "gQ" to start Ex mode.
209
210			The display is not updated while ":normal" is busy.
211
212			{commands} cannot start with a space.  Put a count of
213			1 (one) before it, "1 " is one space.
214
215			The 'insertmode' option is ignored for {commands}.
216
217			This command cannot be followed by another command,
218			since any '|' is considered part of the command.
219
220			This command can be used recursively, but the depth is
221			limited by 'maxmapdepth'.
222
223			An alternative is to use |:execute|, which uses an
224			expression as argument.  This allows the use of
225			printable characters to represent special characters.
226
227			Example: >
228				:exe "normal \<c-w>\<c-w>"
229<			{not in Vi, of course}
230
231:{range}norm[al][!] {commands}				*:normal-range*
232			Execute Normal mode commands {commands} for each line
233			in the {range}.  Before executing the {commands}, the
234			cursor is positioned in the first column of the range,
235			for each line.  Otherwise it's the same as the
236			":normal" command without a range.
237			{not in Vi}
238
239							*:sh* *:shell* *E371*
240:sh[ell]		This command starts a shell.  When the shell exits
241			(after the "exit" command) you return to Vim.  The
242			name for the shell command comes from 'shell' option.
243							*E360*
244			Note: This doesn't work when Vim on the Amiga was
245			started in QuickFix mode from a compiler, because the
246			compiler will have set stdin to a non-interactive
247			mode.
248
249							*:!cmd* *:!* *E34*
250:!{cmd}			Execute {cmd} with the shell.  See also the 'shell'
251			and 'shelltype' option.
252
253			Any '!' in {cmd} is replaced with the previous
254			external command (see also 'cpoptions').  But not when
255			there is a backslash before the '!', then that
256			backslash is removed.  Example: ":!ls" followed by
257			":!echo ! \! \\!" executes "echo ls ! \!".
258
259			A '|' in {cmd} is passed to the shell, you cannot use
260			it to append a Vim command.  See |:bar|.
261
262			If {cmd} contains "%" it is expanded to the current
263			file name.  Special characters are not escaped, use
264			quotes to avoid their special meaning: >
265				:!ls "%"
266<			If the file name contains a "$" single quotes might
267			work better (but a single quote causes trouble): >
268				:!ls '%'
269<			This should always work, but it's more typing: >
270				:exe "!ls " . shellescape(expand("%"))
271<
272			A newline character ends {cmd}, what follows is
273			interpreted as a following ":" command.  However, if
274			there is a backslash before the newline it is removed
275			and {cmd} continues.  It doesn't matter how many
276			backslashes are before the newline, only one is
277			removed.
278
279			On Unix the command normally runs in a non-interactive
280			shell.  If you want an interactive shell to be used
281			(to use aliases) set 'shellcmdflag' to "-ic".
282			For Win32 also see |:!start|.
283
284			After the command has been executed, the timestamp and
285			size of the current file is checked |timestamp|.
286
287			Vim redraws the screen after the command is finished,
288			because it may have printed any text.  This requires a
289			hit-enter prompt, so that you can read any messages.
290			To avoid this use: >
291				:silent !{cmd}
292<			The screen is not redrawn then, thus you have to use
293			CTRL-L or ":redraw!" if the command did display
294			something.
295			Also see |shell-window|.
296
297							*:!!*
298:!!			Repeat last ":!{cmd}".
299
300							*:ve* *:version*
301:ve[rsion]		Print the version number of the editor.  If the
302			compiler used understands "__DATE__" the compilation
303			date is mentioned.  Otherwise a fixed release-date is
304			shown.
305			The following lines contain information about which
306			features were enabled when Vim was compiled.  When
307			there is a preceding '+', the feature is included,
308			when there is a '-' it is excluded.  To change this,
309			you have to edit feature.h and recompile Vim.
310			To check for this in an expression, see |has()|.
311			Here is an overview of the features.
312			The first column shows the smallest version in which
313			they are included:
314			   T	tiny (always)
315			   S	small
316			   N	normal
317			   B	big
318			   H	huge
319			   m	manually enabled or depends on other features
320			 (none) system dependent
321			Thus if a feature is marked with "N", it is included
322			in the normal, big and huge versions of Vim.

486							*/dyn* *E370* *E448*
487			To some of the features "/dyn" is added when the
488			feature is only available when the related library can
489			be dynamically loaded.
490
491:ve[rsion] {nr}		Is now ignored.  This was previously used to check the
492			version number of a .vimrc file.  It was removed,
493			because you can now use the ":if" command for
494			version-dependent behavior.  {not in Vi}
495
496							*:redi* *:redir*
497:redi[r][!] > {file}	Redirect messages to file {file}.  The messages which
498			are the output of commands are written to that file,
499			until redirection ends.  The messages are also still
500			shown on the screen.  When [!] is included, an
501			existing file is overwritten.  When [!] is omitted,
502			and {file} exists, this command fails.
503
504			Only one ":redir" can be active at a time.  Calls to
505			":redir" will close any active redirection before
506			starting redirection to the new target.  For recursive
507			use check out |execute()|.
508
509			To stop the messages and commands from being echoed to
510			the screen, put the commands in a function and call it
511			with ":silent call Function()".
512			An alternative is to use the 'verbosefile' option,
513			this can be used in combination with ":redir".
514			{not in Vi}
515
516:redi[r] >> {file}	Redirect messages to file {file}.  Append if {file}
517			already exists.  {not in Vi}
518
519:redi[r] @{a-zA-Z}
520:redi[r] @{a-zA-Z}>	Redirect messages to register {a-z}.  Append to the
521			contents of the register if its name is given
522			uppercase {A-Z}.  The ">" after the register name is
523			optional. {not in Vi}
524:redi[r] @{a-z}>>	Append messages to register {a-z}. {not in Vi}
525
526:redi[r] @*>
527:redi[r] @+>		Redirect messages to the selection or clipboard. For
528			backward compatibility, the ">" after the register
529			name can be omitted. See |quotestar| and |quoteplus|.
530			{not in Vi}
531:redi[r] @*>>
532:redi[r] @+>>		Append messages to the selection or clipboard.
533			{not in Vi}
534
535:redi[r] @">		Redirect messages to the unnamed register. For
536			backward compatibility, the ">" after the register
537			name can be omitted. {not in Vi}
538:redi[r] @">>		Append messages to the unnamed register. {not in Vi}
539
540:redi[r] => {var}	Redirect messages to a variable.  If the variable
541			doesn't exist, then it is created.  If the variable
542			exists, then it is initialized to an empty string.
543			The variable will remain empty until redirection ends.
544			Only string variables can be used.  After the
545			redirection starts, if the variable is removed or
546			locked or the variable type is changed, then further
547			command output messages will cause errors. {not in Vi}
548			To get the output of one command the |execute()|
549			function can be used.
550
551:redi[r] =>> {var}	Append messages to an existing variable.  Only string
552			variables can be used. {not in Vi}
553
554:redi[r] END		End redirecting messages.  {not in Vi}
555
556							*:filt* *:filter*
557:filt[er][!] {pat} {command}
558:filt[er][!] /{pat}/ {command}
559			Restrict the output of {command} to lines matching
560			with {pat}.  For example, to list only xml files: >
561				:filter /\.xml$/ oldfiles
562<			If the [!] is given, restrict the output of {command}
563			to lines that do NOT match {pat}.
564
565			{pat} is a Vim search pattern.  Instead of enclosing
566			it in / any non-ID character (see |'isident'|) can be
567			used, so long as it does not appear in {pat}.  Without
568			the enclosing character the pattern cannot include the
569			bar character.
570
571			The pattern is matched against the relevant part of
572			the output, not necessarily the whole line. Only some
573			commands support filtering, try it out to check if it
574			works. Some of the commands that support filtering:
575                          |:#|          - filter whole line
576                          |:command|    - filter by command name
577                          |:files|      - filter by file name
578                          |:highlight|  - filter by highlight group
579                          |:jumps|      - filter by file name
580                          |:let|        - filter by variable name
581                          |:list|       - filter whole line
582                          |:llist|      - filter by file name or module name
583                          |:oldfiles|   - filter by file name
584                          |:clist|      - filter by file name or module name
585                          |:set|        - filter by variable name
586
587			Only normal messages are filtered, error messages are
588			not.
589
590						*:sil* *:silent* *:silent!*
591:sil[ent][!] {command}	Execute {command} silently.  Normal messages will not
592			be given or added to the message history.
593			When [!] is added, error messages will also be
594			skipped, and commands and mappings will not be aborted
595			when an error is detected.  |v:errmsg| is still set.
596			When [!] is not used, an error message will cause
597			further messages to be displayed normally.
598			Redirection, started with |:redir|, will continue as
599			usual, although there might be small differences.
600			This will allow redirecting the output of a command
601			without seeing it on the screen.  Example: >
602			    :redir >/tmp/foobar
603			    :silent g/Aap/p
604			    :redir END
605<			To execute a Normal mode command silently, use the
606			|:normal| command.  For example, to search for a
607			string without messages: >
608			    :silent exe "normal /path\<CR>"
609<			":silent!" is useful to execute a command that may
610			fail, but the failure is to be ignored.  Example: >
611			    :let v:errmsg = ""
612			    :silent! /^begin
613			    :if v:errmsg != ""
614			    : ... pattern was not found
615<			":silent" will also avoid the hit-enter prompt.  When
616			using this for an external command, this may cause the
617			screen to be messed up.  Use |CTRL-L| to clean it up
618			then.
619			":silent menu ..." defines a menu that will not echo a
620			Command-line command.  The command will still produce
621			messages though.  Use ":silent" in the command itself
622			to avoid that: ":silent menu .... :silent command".
623
624						*:uns* *:unsilent*
625:uns[ilent] {command}	Execute {command} not silently.  Only makes a
626			difference when |:silent| was used to get to this
627			command.
628			Use this for giving a message even when |:silent| was
629			used.  In this example |:silent| is used to avoid the
630			message about reading the file and |:unsilent| to be
631			able to list the first line of each file. >
632    		:silent argdo unsilent echo expand('%') . ": " . getline(1)
633<
634
635						*:verb* *:verbose*
636:[count]verb[ose] {command}
637			Execute {command} with 'verbose' set to [count].  If
638			[count] is omitted one is used. ":0verbose" can be
639			used to set 'verbose' to zero.
640			The additional use of ":silent" makes messages
641			generated but not displayed.
642			The combination of ":silent" and ":verbose" can be
643			used to generate messages and check them with
644			|v:statusmsg| and friends.  For example: >
645				:let v:statusmsg = ""
646				:silent verbose runtime foobar.vim
647				:if v:statusmsg != ""
648				:  " foobar.vim could not be found
649				:endif
650<			When concatenating another command, the ":verbose"
651			only applies to the first one: >
652				:4verbose set verbose | set verbose
653<				  verbose=4 ~
654				  verbose=0 ~
655			For logging verbose messages in a file use the
656			'verbosefile' option.
657
658							*:verbose-cmd*
659When 'verbose' is non-zero, listing the value of a Vim option or a key map or
660an abbreviation or a user-defined function or a command or a highlight group
661or an autocommand will also display where it was last defined.  If it was
662defined manually then there will be no "Last set" message.  When it was
663defined while executing a function, user command or autocommand, the script in
664which it was defined is reported.
665{not available when compiled without the |+eval| feature}
666
667							*K*
668K			Run a program to lookup the keyword under the
669			cursor.  The name of the program is given with the
670			'keywordprg' (kp) option (default is "man").  The
671			keyword is formed of letters, numbers and the
672			characters in 'iskeyword'.  The keyword under or
673			right of the cursor is used.  The same can be done
674			with the command >
675				:!{program} {keyword}
676<			There is an example of a program to use in the tools
677			directory of Vim.  It is called "ref" and does a
678			simple spelling check.
679			Special cases:
680			- If 'keywordprg' begins with ":" it is invoked as
681			  a Vim Ex command with [count].
682			- If 'keywordprg' is empty, the ":help" command is
683			  used.  It's a good idea to include more characters
684			  in 'iskeyword' then, to be able to find more help.
685			- When 'keywordprg' is equal to "man" or starts with
686			  ":", a [count] before "K" is inserted after
687			  keywordprg and before the keyword.  For example,
688			  using "2K" while the cursor is on "mkdir", results
689			  in: >
690				!man 2 mkdir
691<			- When 'keywordprg' is equal to "man -s", a count
692			  before "K" is inserted after the "-s".  If there is
693			  no count, the "-s" is removed.
694			{not in Vi}
695
696							*v_K*
697{Visual}K		Like "K", but use the visually highlighted text for
698			the keyword.  Only works when the highlighted text is
699			not more than one line.  {not in Vi}
700
701[N]gs							*gs* *:sl* *:sleep*
702:[N]sl[eep] [N]	[m]	Do nothing for [N] seconds.  When [m] is included,
703			sleep for [N] milliseconds.  The count for "gs" always
704			uses seconds.  The default is one second. >
705			     :sleep	     "sleep for one second
706			     :5sleep	     "sleep for five seconds
707			     :sleep 100m     "sleep for a hundred milliseconds
708			     10gs	     "sleep for ten seconds
709<			Can be interrupted with CTRL-C (CTRL-Break on MS-DOS).
710			"gs" stands for "goto sleep".
711			While sleeping the cursor is positioned in the text,
712			if at a visible position.  {not in Vi}
713			Also process the received netbeans messages. {only
714			available when compiled with the |+netbeans_intg|
715			feature}
716
717
718							*g_CTRL-A*
719g CTRL-A		Only when Vim was compiled with MEM_PROFILING defined
720			(which is very rare): print memory usage statistics.
721			Only useful for debugging Vim.
722			For incrementing in Visual mode see |v_g_CTRL-A|.

724==============================================================================
7252. Using Vim like less or more					*less*
726
727If you use the less or more program to view a file, you don't get syntax
728highlighting.  Thus you would like to use Vim instead.  You can do this by
729using the shell script "$VIMRUNTIME/macros/less.sh".
730
731This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim".  It sets
732up mappings to simulate the commands that less supports.  Otherwise, you can
733still use the Vim commands.
734
735This isn't perfect.  For example, when viewing a short file Vim will still use
736the whole screen.  But it works good enough for most uses, and you get syntax
737highlighting.
738
739The "h" key will give you a short overview of the available commands.
740
741If you want to set options differently when using less, define the
742LessInitFunc in your vimrc, for example: >
743
744	func LessInitFunc()
745	  set nocursorcolumn nocursorline
746	endfunc
