14 1. Various commands *various-cmds*
17 CTRL-L Clear and redraw the screen. The redraw may happen
18 later, after processing typeahead.
21 :redr[aw][!] Redraw the screen right now. When ! is included it is
23 Useful to update the screen halfway executing a script
24 or function. Also when halfway a mapping and
27 *:redraws* *:redrawstatus*
28 :redraws[tatus][!] Redraw the status line of the current window. When !
29 is included all status lines are redrawn.
30 Useful to update the status line(s) when 'statusline'
31 includes an item that doesn't cause automatic
35 <Del> When entering a number: Remove the last digit.
36 Note: if you like to use <BS> for this, add this
37 mapping to your .vimrc: >
38 :map CTRL-V <BS> CTRL-V <Del>
39 < See |:fixdel| if your <Del> key does not do what you
42 :as[cii] or *ga* *:as* *:ascii*
43 ga Print the ascii value of the character under the
44 cursor in decimal, hexadecimal and octal. For
45 example, when the cursor is on a 'R':
46 <R> 82, Hex 52, Octal 122 ~
47 When the character is a non-standard ASCII character,
48 but printable according to the 'isprint' option, the
49 non-printable version is also given. When the
50 character is larger than 127, the <M-x> form is also
52 <~A> <M-^A> 129, Hex 81, Octal 201 ~
53 <p> <|~> <M-~> 254, Hex fe, Octal 376 ~
54 (where <p> is a special character)
55 The <Nul> character in a file is stored internally as
56 <NL>, but it will be shown as:
57 <^@> 0, Hex 00, Octal 000 ~
58 If the character has composing characters these are
59 also shown. The value of 'maxcombine' doesn't matter.
60 Mnemonic: Get Ascii value. {not in Vi}
63 g8 Print the hex values of the bytes used in the
64 character under the cursor, assuming it is in |UTF-8|
65 encoding. This also shows composing characters. The
66 value of 'maxcombine' doesn't matter.
67 Example of a character with two composing characters:
68 e0 b8 81 + e0 b8 b9 + e0 b9 89 ~
69 {not in Vi} {only when compiled with the |+multi_byte|
73 8g8 Find an illegal UTF-8 byte sequence at or after the
74 cursor. This works in two situations:
75 1. when 'encoding' is any 8-bit encoding
76 2. when 'encoding' is "utf-8" and 'fileencoding' is
78 Thus it can be used when editing a file that was
79 supposed to be UTF-8 but was read as if it is an 8-bit
80 encoding because it contains illegal bytes.
81 Does not wrap around the end of the file.
82 Note that when the cursor is on an illegal byte or the
83 cursor is halfway a multi-byte character the command
84 won't move the cursor.
85 {not in Vi} {only when compiled with the |+multi_byte|
88 *:p* *:pr* *:print* *E749*
89 :[range]p[rint] [flags]
90 Print [range] lines (default current line).
91 Note: If you are looking for a way to print your text
92 on paper see |:hardcopy|. In the GUI you can use the
93 File.Print menu entry.
94 See |ex-flags| for [flags].
96 :[range]p[rint] {count} [flags]
97 Print {count} lines, starting with [range] (default
98 current line |cmdline-ranges|).
99 See |ex-flags| for [flags].
102 :[range]P[rint] [count] [flags]
103 Just as ":print". Was apparently added to Vi for
104 people that keep the shift key pressed too long...
105 See |ex-flags| for [flags].
108 :[range]l[ist] [count] [flags]
109 Same as :print, but display unprintable characters
110 with '^' and put $ after the line.
111 See |ex-flags| for [flags].
114 :[range]nu[mber] [count] [flags]
115 Same as :print, but precede each line with its line
116 number. (See also 'highlight' and 'numberwidth'
118 See |ex-flags| for [flags].
121 :[range]# [count] [flags]
125 :#!{anything} Ignored, so that you can start a Vim script with: >
127 echo "this is a Vim script"
131 :{range}z[+-^.=]{count} Display several lines of text surrounding the line
132 specified with {range}, or around the current line
133 if there is no {range}. If there is a {count}, that's
134 how many lines you'll see; if there is only one window
135 then the 'window' option is used, otherwise the
136 current window size is used.
138 :z can be used either alone or followed by any of
139 several punctuation marks. These have the following
142 mark first line last line new location ~
143 ---- ---------- --------- ------------
144 + current line 1 scr forward 1 scr forward
145 - 1 scr back current line current line
146 ^ 2 scr back 1 scr back 1 scr back
147 . 1/2 scr back 1/2 scr fwd 1/2 scr fwd
148 = 1/2 scr back 1/2 scr fwd current line
150 Specifying no mark at all is the same as "+".
151 If the mark is "=", a line of dashes is printed
152 around the current line.
154 :{range}z#[+-^.=]{count} *:z#*
155 Like ":z", but number the lines.
156 {not in all versions of Vi, not with these arguments}
159 := [flags] Print the last line number.
160 See |ex-flags| for [flags].
162 :{range}= [flags] Prints the last line number in {range}. For example,
163 this prints the current line number: >
165 < See |ex-flags| for [flags].
167 :norm[al][!] {commands} *:norm* *:normal*
168 Execute Normal mode commands {commands}. This makes
169 it possible to execute Normal mode commands typed on
170 the command-line. {commands} is executed like it is
171 typed. For undo all commands are undone together.
172 Execution stops when an error is encountered.
173 If the [!] is given, mappings will not be used.
174 {commands} should be a complete command. If
175 {commands} does not finish a command, the last one
176 will be aborted as if <Esc> or <C-C> was typed.
177 The display isn't updated while ":normal" is busy.
178 This implies that an insert command must be completed
179 (to start Insert mode, see |:startinsert|). A ":"
180 command must be completed as well. And you can't use
181 "Q" or "gQ" to start Ex mode.
182 {commands} cannot start with a space. Put a count of
183 1 (one) before it, "1 " is one space.
184 The 'insertmode' option is ignored for {commands}.
185 This command cannot be followed by another command,
186 since any '|' is considered part of the command.
187 This command can be used recursively, but the depth is
188 limited by 'maxmapdepth'.
189 When this command is called from a non-remappable
190 mapping |:noremap|, the argument can be mapped anyway.
191 An alternative is to use |:execute|, which uses an
192 expression as argument. This allows the use of
193 printable characters. Example: >
194 :exe "normal \<c-w>\<c-w>"
195 < {not in Vi, of course}
196 {not available when the |+ex_extra| feature was
197 disabled at compile time}
199 :{range}norm[al][!] {commands} *:normal-range*
200 Execute Normal mode commands {commands} for each line
201 in the {range}. Before executing the {commands}, the
202 cursor is positioned in the first column of the range,
203 for each line. Otherwise it's the same as the
204 ":normal" command without a range.
206 Not available when |+ex_extra| feature was disabled at
209 *:sh* *:shell* *E371*
210 :sh[ell] This command starts a shell. When the shell exits
211 (after the "exit" command) you return to Vim. The
212 name for the shell command comes from 'shell' option.
214 Note: This doesn't work when Vim on the Amiga was
215 started in QuickFix mode from a compiler, because the
216 compiler will have set stdin to a non-interactive
220 :!{cmd} Execute {cmd} with the shell. See also the 'shell'
221 and 'shelltype' option.
222 Any '!' in {cmd} is replaced with the previous
223 external command (see also 'cpoptions'). But not when
224 there is a backslash before the '!', then that
225 backslash is removed. Example: ":!ls" followed by
226 ":!echo ! \! \\!" executes "echo ls ! \!".
227 After the command has been executed, the timestamp of
228 the current file is checked |timestamp|.
229 A '|' in {cmd} is passed to the shell, you cannot use
230 it to append a Vim command. See |:bar|.
231 A newline character ends {cmd}, what follows is
232 interpreted as a following ":" command. However, if
233 there is a backslash before the newline it is removed
234 and {cmd} continues. It doesn't matter how many
235 backslashes are before the newline, only one is
237 On Unix the command normally runs in a non-interactive
238 shell. If you want an interactive shell to be used
239 (to use aliases) set 'shellcmdflag' to "-ic".
240 For Win32 also see |:!start|.
241 Vim redraws the screen after the command is finished,
242 because it may have printed any text. This requires a
243 hit-enter prompt, so that you can read any messages.
246 < The screen is not redrawn then, thus you have to use
247 CTRL-L or ":redraw!" if the command did display
249 Also see |shell-window|.
252 :!! Repeat last ":!{cmd}".
255 :ve[rsion] Print the version number of the editor. If the
256 compiler used understands "__DATE__" the compilation
257 date is mentioned. Otherwise a fixed release-date is
259 The following lines contain information about which
260 features were enabled when Vim was compiled. When
261 there is a preceding '+', the feature is included,
262 when there is a '-' it is excluded. To change this,
263 you have to edit feature.h and recompile Vim.
264 To check for this in an expression, see |has()|.
265 Here is an overview of the features.
266 The first column shows the smallest version in which
273 m manually enabled or depends on other features

416 To some of the features "/dyn" is added when the
417 feature is only available when the related library can
418 be dynamically loaded.
420 :ve[rsion] {nr} Is now ignored. This was previously used to check the
421 version number of a .vimrc file. It was removed,
422 because you can now use the ":if" command for
423 version-dependent behavior. {not in Vi}
426 :redi[r][!] > {file} Redirect messages to file {file}. The messages which
427 are the output of commands are written to that file,
428 until redirection ends. The messages are also still
429 shown on the screen. When [!] is included, an
430 existing file is overwritten. When [!] is omitted,
431 and {file} exists, this command fails.
432 Only one ":redir" can be active at a time. Calls to
433 ":redir" will close any active redirection before
434 starting redirection to the new target.
435 To stop the messages and commands from being echoed to
436 the screen, put the commands in a function and call it
437 with ":silent call Function()".
438 An alternative is to use the 'verbosefile' option,
439 this can be used in combination with ":redir".
442 :redi[r] >> {file} Redirect messages to file {file}. Append if {file}
443 already exists. {not in Vi}
446 :redi[r] @{a-zA-Z}> Redirect messages to register {a-z}. Append to the
447 contents of the register if its name is given
448 uppercase {A-Z}. The ">" after the register name is
449 optional. {not in Vi}
450 :redi[r] @{a-z}>> Append messages to register {a-z}. {not in Vi}
453 :redi[r] @+> Redirect messages to the selection or clipboard. For
454 backward compatibility, the ">" after the register
455 name can be omitted. See |quotestar| and |quoteplus|.
458 :redi[r] @+>> Append messages to the selection or clipboard.
461 :redi[r] @"> Redirect messages to the unnamed register. For
462 backward compatibility, the ">" after the register
463 name can be omitted. {not in Vi}
464 :redi[r] @">> Append messages to the unnamed register. {not in Vi}
466 :redi[r] => {var} Redirect messages to a variable. If the variable
467 doesn't exist, then it is created. If the variable
468 exists, then it is initialized to an empty string.
469 The variable will remain empty until redirection ends.
470 Only string variables can be used. After the
471 redirection starts, if the variable is removed or
472 locked or the variable type is changed, then further
473 command output messages will cause errors. {not in Vi}
475 :redi[r] =>> {var} Append messages to an existing variable. Only string
476 variables can be used. {not in Vi}
478 :redi[r] END End redirecting messages. {not in Vi}
481 :sil[ent][!] {command} Execute {command} silently. Normal messages will not
482 be given or added to the message history.
483 When [!] is added, error messages will also be
484 skipped, and commands and mappings will not be aborted
485 when an error is detected. |v:errmsg| is still set.
486 When [!] is not used, an error message will cause
487 further messages to be displayed normally.
488 Redirection, started with |:redir|, will continue as
489 usual, although there might be small differences.
490 This will allow redirecting the output of a command
491 without seeing it on the screen. Example: >
495 < To execute a Normal mode command silently, use the
496 |:normal| command. For example, to search for a
497 string without messages: >
498 :silent exe "normal /path\<CR>"
499 < ":silent!" is useful to execute a command that may
500 fail, but the failure is to be ignored. Example: >
504 : ... pattern was not found
505 < ":silent" will also avoid the hit-enter prompt. When
506 using this for an external command, this may cause the
507 screen to be messed up. Use |CTRL-L| to clean it up
509 ":silent menu ..." defines a menu that will not echo a
510 Command-line command. The command will still produce
511 messages though. Use ":silent" in the command itself
512 to avoid that: ":silent menu .... :silent command".
515 :uns[ilent] {command} Execute {command} not silently. Only makes a
516 difference when |:silent| was used to get to this
518 Use this for giving a message even when |:silent| was
519 used. In this example |:silent| is used to avoid the
520 message about reading the file and |:unsilent| to be
521 able to list the first line of each file. >
522 :silent argdo unsilent echo expand('%') . ": " . getline(1)
526 :[count]verb[ose] {command}
527 Execute {command} with 'verbose' set to [count]. If
528 [count] is omitted one is used. ":0verbose" can be
529 used to set 'verbose' to zero.
530 The additional use of ":silent" makes messages
531 generated but not displayed.
532 The combination of ":silent" and ":verbose" can be
533 used to generate messages and check them with
534 |v:statusmsg| and friends. For example: >
535 :let v:statusmsg = ""
536 :silent verbose runtime foobar.vim
537 :if v:statusmsg != ""
538 : " foobar.vim could not be found
540 < When concatenating another command, the ":verbose"
541 only applies to the first one: >
542 :4verbose set verbose | set verbose
545 For logging verbose messages in a file use the
546 'verbosefile' option.
549 When 'verbose' is non-zero, listing the value of a Vim option or a key map or
550 an abbreviation or a user-defined function or a command or a highlight group
551 or an autocommand will also display where it was last defined. If it was
552 defined manually then there will be no "Last set" message. When it was
553 defined while executing a function, user command or autocommand, the script in
554 which it was defined is reported.
555 {not available when compiled without the +eval feature}
558 K Run a program to lookup the keyword under the
559 cursor. The name of the program is given with the
560 'keywordprg' (kp) option (default is "man"). The
561 keyword is formed of letters, numbers and the
562 characters in 'iskeyword'. The keyword under or
563 right of the cursor is used. The same can be done
565 :!{program} {keyword}
566 < There is an example of a program to use in the tools
567 directory of Vim. It is called 'ref' and does a
568 simple spelling check.
570 - If 'keywordprg' is empty, the ":help" command is
571 used. It's a good idea to include more characters
572 in 'iskeyword' then, to be able to find more help.
573 - When 'keywordprg' is equal to "man", a count before
574 "K" is inserted after the "man" command and before
575 the keyword. For example, using "2K" while the
576 cursor is on "mkdir", results in: >
578 < - When 'keywordprg' is equal to "man -s", a count
579 before "K" is inserted after the "-s". If there is
580 no count, the "-s" is removed.
584 {Visual}K Like "K", but use the visually highlighted text for
585 the keyword. Only works when the highlighted text is
586 not more than one line. {not in Vi}
588 [N]gs *gs* *:sl* *:sleep*
589 :[N]sl[eep] [N] [m] Do nothing for [N] seconds. When [m] is included,
590 sleep for [N] milliseconds. The count for "gs" always
591 uses seconds. The default is one second. >
592 :sleep "sleep for one second
593 :5sleep "sleep for five seconds
594 :sleep 100m "sleep for a hundred milliseconds
595 10gs "sleep for ten seconds
596 < Can be interrupted with CTRL-C (CTRL-Break on MS-DOS).
597 "gs" stands for "goto sleep".
598 While sleeping the cursor is positioned in the text,
599 if at a visible position. {not in Vi}

607 2. Online help *online-help*
609 *help* *<Help>* *:h* *:help* *<F1>* *i_<F1>* *i_<Help>*
611 :h[elp] Open a window and display the help file in read-only
612 mode. If there is a help window open already, use
613 that one. Otherwise, if the current window uses the
614 full width of the screen or is at least 80 characters
615 wide, the help window will appear just above the
616 current window. Otherwise the new window is put at
618 The 'helplang' option is used to select a language, if
619 the main help file is available in several languages.
622 *{subject}* *E149* *E661*
623 :h[elp] {subject} Like ":help", additionally jump to the tag {subject}.
624 {subject} can include wildcards like "*", "?" and
626 :help z? jump to help for any "z" command
627 :help z. jump to the help for "z."
628 If there is no full match for the pattern, or there
629 are several matches, the "best" match will be used.
630 A sophisticated algorithm is used to decide which
631 match is better than another one. These items are
632 considered in the computation:
633 - A match with same case is much better than a match
635 - A match that starts after a non-alphanumeric
636 character is better than a match in the middle of a
638 - A match at or near the beginning of the tag is
639 better than a match further on.
640 - The more alphanumeric characters match, the better.
641 - The shorter the length of the match, the better.
643 The 'helplang' option is used to select a language, if
644 the {subject} is available in several languages.
645 To find a tag in a specific language, append "@ab",
646 where "ab" is the two-letter language code. See
649 Note that the longer the {subject} you give, the less
650 matches will be found. You can get an idea how this
651 all works by using commandline completion (type CTRL-D
652 after ":help subject" |c_CTRL-D|).
653 If there are several matches, you can have them listed
654 by hitting CTRL-D. Example: >
656 < To use a regexp |pattern|, first do ":help" and then
657 use ":tag {pattern}" in the help window. The
658 ":tnext" command can then be used to jump to other
659 matches, "tselect" to list matches and choose one. >
661 < When there is no argument you will see matches for
662 "help", to avoid listing all possible matches (that
664 The number of matches displayed is limited to 300.
666 This command can be followed by '|' and another
667 command, but you don't need to escape the '|' inside a
668 help command. So these both work: >
671 < Note that a space before the '|' is seen as part of
672 the ":help" argument.
673 You can also use <LF> or <CR> to separate the help
674 command from a following command. You need to type
675 CTRL-V first to insert the <LF> or <CR>. Example: >
676 :help so<C-V><CR>only
679 :h[elp]! [subject] Like ":help", but in non-English help files prefer to
680 find a tag in a file with the same language as the
681 current file. See |help-translated|.
684 :helpg[rep] {pattern}[@xx]
685 Search all help text files and make a list of lines
686 in which {pattern} matches. Jumps to the first match.
687 The optional [@xx] specifies that only matches in the
688 "xx" language are to be found.
689 You can navigate through the matches with the
690 |quickfix| commands, e.g., |:cnext| to jump to the
691 next one. Or use |:cwindow| to get the list of
692 matches in the quickfix window.
693 {pattern} is used as a Vim regexp |pattern|.
694 'ignorecase' is not used, add "\c" to ignore case.
695 Example for case sensitive search: >
697 < Example for case ignoring search: >
699 < Example for searching in French help: >
700 :helpgrep backspace@fr
701 < The pattern does not support line breaks, it must
702 match within one line. You can use |:grep| instead,
703 but then you need to get the list of help files in a
705 Cannot be followed by another command, everything is
706 used as part of the pattern. But you can use
707 |:execute| when needed.
708 Compressed help files will not be searched (Fedora
709 compresses the help files).
713 :lh[elpgrep] {pattern}[@xx]
714 Same as ":helpgrep", except the location list is used
715 instead of the quickfix list. If the help window is
716 already opened, then the location list for that window
717 is used. Otherwise, a new help window is opened and
718 the location list for that window is set. The
719 location list for the current window is not changed.
722 :exu[sage] Show help on Ex commands. Added to simulate the Nvi
726 :viu[sage] Show help on Normal mode commands. Added to simulate
727 the Nvi command. {not in Vi}
729 When no argument is given to |:help| the file given with the 'helpfile' option
730 will be opened. Otherwise the specified tag is searched for in all "doc/tags"
731 files in the directories specified in the 'runtimepath' option.
733 The initial height of the help window can be set with the 'helpheight' option
736 Jump to specific subjects by using tags. This can be done in two ways:
737 - Use the "CTRL-]" command while standing on the name of a command or option.
738 This only works when the tag is a keyword. "<C-Leftmouse>" and
739 "g<LeftMouse>" work just like "CTRL-]".
740 - use the ":ta {subject}" command. This also works with non-keyword
743 Use CTRL-T or CTRL-O to jump back.
744 Use ":q" to close the help window.
746 If there are several matches for an item you are looking for, this is how you
747 can jump to each one of them:
748 1. Open a help window
749 2. Use the ":tag" command with a slash prepended to the tag. E.g.: >
751 3. Use ":tnext" to jump to the next matching tag.
753 It is possible to add help files for plugins and other items. You don't need
754 to change the distributed help files for that. See |add-local-help|.
756 To write a local help file, see |write-local-help|.
758 Note that the title lines from the local help files are automagically added to
759 the "LOCAL ADDITIONS" section in the "help.txt" help file |local-additions|.
760 This is done when viewing the file in Vim, the file itself is not changed. It
761 is done by going through all help files and obtaining the first line of each
762 file. The files in $VIMRUNTIME/doc are skipped.
765 If you want to have the help in another xterm window, you could use this
767 :!xterm -e vim +help &
771 :helpf[ind] Like |:help|, but use a dialog to enter the argument.
772 Only for backwards compatibility. It now executes the
773 ToolBar.FindHelp menu entry instead of using a builtin
774 dialog. {only when compiled with |+GUI_GTK|}
778 *E154* *E150* *E151* *E152* *E153* *E670*
779 :helpt[ags] [++t] {dir}
780 Generate the help tags file(s) for directory {dir}.
781 All "*.txt" and "*.??x" files in the directory are
782 scanned for a help tag definition in between stars.
783 The "*.??x" files are for translated docs, they
784 generate the "tags-??" file, see |help-translated|.
785 The generated tags files are sorted.
786 When there are duplicates an error message is given.
787 An existing tags file is silently overwritten.
788 The optional "++t" argument forces adding the
789 "help-tags" tag. This is also done when the {dir} is
790 equal to $VIMRUNTIME/doc.
791 To rebuild the help tags in the runtime directory
792 (requires write permission there): >
793 :helptags $VIMRUNTIME/doc
797 TRANSLATED HELP *help-translated*
799 It is possible to add translated help files, next to the original English help
800 files. Vim will search for all help in "doc" directories in 'runtimepath'.
801 This is only available when compiled with the |+multi_lang| feature.
803 At this moment translations are available for:
804 Chinese - multiple authors
805 French - translated by David Blanchet
806 Italian - translated by Antonio Colombo
807 Polish - translated by Mikolaj Machowski
808 Russian - translated by Vassily Ragosin
809 See the Vim website to find them: http://www.vim.org/translations.php
811 A set of translated help files consists of these files:
818 "ab" is the two-letter language code. Thus for Italian the names are:
825 The 'helplang' option can be set to the preferred language(s). The default is
826 set according to the environment. Vim will first try to find a matching tag
827 in the preferred language(s). English is used when it cannot be found.
829 To find a tag in a specific language, append "@ab" to a tag, where "ab" is the
830 two-letter language code. Example: >
833 The first one finds the Italian user manual, even when 'helplang' is empty.
834 The second one finds the English user manual, even when 'helplang' is set to
837 When using command-line completion for the ":help" command, the "@en"
838 extension is only shown when a tag exists for multiple languages. When the
839 tag only exists for English "@en" is omitted.
841 When using |CTRL-]| or ":help!" in a non-English help file Vim will try to
842 find the tag in the same language. If not found then 'helplang' will be used
843 to select a language.
845 Help files must use latin1 or utf-8 encoding. Vim assumes the encoding is
846 utf-8 when finding non-ASCII characters in the first line. Thus you must
847 translate the header with "For Vim version".
849 The same encoding must be used for the help files of one language in one
850 directory. You can use a different encoding for different languages and use
851 a different encoding for help files of the same language but in a different
854 Hints for translators:
855 - Do not translate the tags. This makes it possible to use 'helplang' to
856 specify the preferred language. You may add new tags in your language.
857 - When you do not translate a part of a file, add tags to the English version,
858 using the "tag@en" notation.
859 - Make a package with all the files and the tags file available for download.
860 Users can drop it in one of the "doc" directories and start use it.
861 Report this to Bram, so that he can add a link on www.vim.org.
862 - Use the |:helptags| command to generate the tags files. It will find all
863 languages in the specified directory.
865 ==============================================================================
866 3. Using Vim like less or more *less*
868 If you use the less or more program to view a file, you don't get syntax
869 highlighting. Thus you would like to use Vim instead. You can do this by
870 using the shell script "$VIMRUNTIME/macros/less.sh".
872 This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim". It sets
873 up mappings to simulate the commands that less supports. Otherwise, you can
874 still use the Vim commands.
876 This isn't perfect. For example, when viewing a short file Vim will still use
877 the whole screen. But it works good enough for most uses, and you get syntax
880 The "h" key will give you a short overview of the available commands.
