*various.txt* For Vim version 9.1. Last change: 2025 Aug 18
VIM REFERENCE MANUAL by Bram Moolenaar
Various commands *various*
1. Various commands |various-cmds|
2. Using Vim like less or more |less|
==============================================================================
1. Various commands *various-cmds*
*CTRL-L*
CTRL-L Clear and redraw the screen. The redraw may happen
later, after processing typeahead.
*:redr* *:redraw*
:redr[aw][!] Redraw the screen right now. When ! is included it is
cleared first.
It can be used to redraw the screen in a script
or function (or a mapping if 'lazyredraw' is set).
*:redraws* *:redrawstatus*
:redraws[tatus][!] Redraw the status line of the current window. When !
is included all status lines are redrawn.
Useful to update the status line(s) when 'statusline'
includes an item that doesn't cause automatic
updating.
If the command line is being edited the redraw is
postponed until later.
*:redrawt* *:redrawtabline*
:redrawt[abline] Redraw the tabline. Useful to update the tabline when
'tabline' includes an item that doesn't trigger
automatic updating.
*E1547* *:redrawtabp* *:redrawtabpanel*
:redrawtabp[anel] Redraw the tabpanel Useful to update the tabpanel
when 'tabpanel' includes an item that doesn't trigger
automatic updating.
*N<Del>*
<Del> When entering a number: Remove the last digit.
Note: if you like to use <BS> for this, add this
mapping to your .vimrc: >
:map CTRL-V <BS> CTRL-V <Del>
< See |:fixdel| if your <Del> key does not do what you
want.
:as[cii] or *ga* *:as* *:ascii*
ga Print the ascii value of the character under the
cursor in decimal, hexadecimal and octal.
Mnemonic: Get Ascii value.
For example, when the cursor is on a 'R':
<R> 82, Hex 52, Octal 122 ~
When the character is a non-standard ASCII character,
but printable according to the 'isprint' option, the
non-printable version is also given.
When the character is larger than 127, the <M-x> form
is also printed. For example:
<~A> <M-^A> 129, Hex 81, Octal 201 ~
<p> <|~> <M-~> 254, Hex fe, Octal 376 ~
(where <p> is a special character)
The <Nul> character in a file is stored internally as
<NL>, but it will be shown as:
<^@> 0, Hex 00, Octal 000 ~
If the character has composing characters these are
also shown. The value of 'maxcombine' doesn't matter.
If the character can be inserted as a digraph, also
output the two characters that can be used to create
the character:
<ö> 246, Hex 00f6, Oct 366, Digr o: ~
This shows you can type CTRL-K o : to insert ö.
*g8*
g8 Print the hex values of the bytes used in the
character under the cursor, assuming it is in |UTF-8|
encoding. This also shows composing characters. The
value of 'maxcombine' doesn't matter.
Example of a character with two composing characters:
e0 b8 81 + e0 b8 b9 + e0 b9 89 ~
*8g8*
8g8 Find an illegal UTF-8 byte sequence at or after the
cursor. This works in two situations:
1. when 'encoding' is any 8-bit encoding
2. when 'encoding' is "utf-8" and 'fileencoding' is
any 8-bit encoding
Thus it can be used when editing a file that was
supposed to be UTF-8 but was read as if it is an 8-bit
encoding because it contains illegal bytes.
Does not wrap around the end of the file.
Note that when the cursor is on an illegal byte or the
cursor is halfway a multibyte character the command
won't move the cursor.
*:p* *:pr* *:print* *E749*
:[range]p[rint] [flags]
Print [range] lines (default current line). Can also
be spelled `:[range]|` due to Vi compatibility (see
|:bar|). Gives an error in an empty buffer.
Note: If you are looking for a way to print your text
on paper see |:hardcopy|. In the GUI you can use the
File.Print menu entry.
See |ex-flags| for [flags].
The |:filter| command can be used to only show lines
matching a pattern.
:[range]p[rint] {count} [flags]
Print {count} lines, starting with [range] (default
current line |cmdline-ranges|).
See |ex-flags| for [flags].
*:P* *:Print*
:[range]P[rint] [count] [flags]
Just as ":print". Was apparently added to Vi for
people that keep the shift key pressed too long...
This command is not supported in |Vim9| script.
Note: A user command can overrule this command.
See |ex-flags| for [flags].
*:l* *:list*
:[range]l[ist] [count] [flags]
Same as :print, but display unprintable characters
with '^' and put $ after the line. This can be
further changed with the 'listchars' option.
See |ex-flags| for [flags].
*:nu* *:number*
:[range]nu[mber] [count] [flags]
Same as :print, but precede each line with its line
number. (See also 'highlight' and 'numberwidth'
option).
See |ex-flags| for [flags].
*:#*
:[range]# [count] [flags]
synonym for :number.
*:#!* *vim-shebang*
:#!{anything} Ignored, so that you can start a Vim script with: >
#!vim -S
let mylogbook='$HOME/logbook.md'
exe $':e {mylogbook}'
$
put ='## ' .. strftime('%d. %b %Y')
norm! o
<
Make that script executable and run it to create a
new diary entry.
*:z* *E144*
:[range]z[+-^.=][count] Display several lines of text surrounding the line
specified with [range], or around the current line
if there is no [range].
If there is a [count], that's how many lines you'll
see; if there is no [count] and only one window then
twice the value of the 'scroll' option is used,
otherwise the current window height minus 3 is used.
This is the value of "scr" in the table below.
If there is a [count] the 'window' option is set to
its value.
:z can be used either alone or followed by any of
several marks. These have the following effect:
mark first line last line new cursor line ~
---- ---------- --------- ------------
+ current line 1 scr forward 1 scr forward
- 1 scr back current line current line
^ 2 scr back 1 scr back 1 scr back
. 1/2 scr back 1/2 scr fwd 1/2 scr fwd
= 1/2 scr back 1/2 scr fwd current line
Specifying no mark at all is the same as "+".
If the mark is "=", a line of dashes is printed
around the current line.
*:z!*
:[range]z![+-^.=][count]
Like ":z", but when [count] is not specified, it
defaults to the Vim window height minus one.
:[range]z[!]#[+-^.=][count] *:z#*
Like ":z" or ":z!", but number the lines.
*:=*
:= [flags] Print the last line number.
See |ex-flags| for [flags].
:{range}= [flags] Prints the last line number in {range}. For example,
this prints the current line number: >
:.=
< See |ex-flags| for [flags].
:norm[al][!] {commands} *:norm* *:normal*
Execute Normal mode commands {commands}. This makes
it possible to execute Normal mode commands typed on
the command-line. {commands} are executed like they
are typed. For undo all commands are undone together.
Execution stops when an error is encountered.
If the [!] is given, mappings will not be used.
Without it, when this command is called from a
non-remappable mapping (|:noremap|), the argument can
be mapped anyway.
{commands} should be a complete command. If
{commands} does not finish a command, the last one
will be aborted as if <Esc> or <C-C> was typed.
This implies that an insert command must be completed
(to start Insert mode, see |:startinsert|). A ":"
command must be completed as well. And you can't use
"Q" or "gQ" to start Ex mode.
The display is not updated while ":normal" is busy.
{commands} cannot start with a space. Put a count of
1 (one) before it, "1 " is one space.
The 'insertmode' option is ignored for {commands}.
This command cannot be followed by another command,
since any '|' is considered part of the command.
This command can be used recursively, but the depth is
limited by 'maxmapdepth'.
An alternative is to use |:execute|, which uses an
expression as argument. This allows the use of
printable characters to represent special characters.
Example: >
:exe "normal \<c-w>\<c-w>"
:{range}norm[al][!] {commands} *:normal-range*
Execute Normal mode commands {commands} for each line
in the {range}. Before executing the {commands}, the
cursor is positioned in the first column of the range,
for each line. Otherwise it's the same as the
":normal" command without a range.
*:sh* *:shell* *E371*
:sh[ell] This command starts a shell. When the shell exits
(after the "exit" command) you return to Vim. The
name for the shell command comes from 'shell' option.
*E360*
Note: This doesn't work when Vim on the Amiga was
started in QuickFix mode from a compiler, because the
compiler will have set stdin to a non-interactive
mode.
*:!cmd* *:!*
:!{cmd} Execute {cmd} with the shell. See also the 'shell'
and 'shelltype' option. For the filter command, see
|:range!|.
Vim builds command line using options 'shell', 'shcf',
'sxq' and 'shq' in the following order:
`&sh &shcf &sxq &shq {cmd} &shq &sxq`
So setting both 'sxq' and 'shq' is possible but rarely
useful. Additional escaping inside `{cmd}` may also
be due to 'sxe' option.
Also, all |cmdline-special| characters in {cmd} are
replaced by Vim before passing them to shell.
*E34*
Any '!' in {cmd} is replaced with the previous
external command (see also 'cpoptions'). But not when
there is a backslash before the '!', then that
backslash is removed. Example: ":!ls" followed by
":!echo ! \! \\!" executes "echo ls ! \!".
A '|' in {cmd} is passed to the shell, you cannot use
it to append a Vim command. See |:bar|.
If {cmd} contains "%" it is expanded to the current
file name, "#" is expanded to the alternate file name.
Special characters in the file name are not escaped,
use quotes to avoid their special meaning: >
:!ls "%"
< If the file name contains a "$" then single quotes
might work better, but this only works if the file
name does not contain a single quote: >
:!ls '%'
< This should always work, but it's more typing: >
:exe "!ls " .. shellescape(expand("%"))
< To get a literal "%" or "#" prepend it with a
backslash. For example, to list all files starting
with "%": >
:!ls \%*
<
A newline character ends {cmd}, what follows is
interpreted as a following ":" command. However, if
there is a backslash before the newline it is removed
and {cmd} continues. It doesn't matter how many
backslashes are before the newline, only one is
removed.
On Unix the command normally runs in a non-interactive
shell. If you want an interactive shell to be used
(to use aliases) set 'shellcmdflag' to "-ic".
For Win32 also see |:!start|.
After the command has been executed, the timestamp and
size of the current file is checked |timestamp|.
Vim redraws the screen after the command is finished,
because it may have printed any text. This requires a
hit-enter prompt, so that you can read any messages.
To avoid this use: >
:silent !{cmd}
< The screen is not redrawn then, thus you have to use
CTRL-L or ":redraw!" if the command did display
something. However, this depends on what the |t_ti|
and |t_te| termcap entries are set to.
Hint: use |:terminal| command if you want to run {cmd}
in Vim window. `:term ++shell ++close {cmd}` could
serve as close approximation to what `:!{cmd}` does.
*:!!*
:!! Repeat last ":!{cmd}".
*:ve* *:ver* *:version*
:ve[rsion] Print the version number of the editor. If the
compiler used understands "__DATE__" the compilation
date is mentioned. Otherwise a fixed release-date is
shown.
The following lines contain information about which
features were enabled when Vim was compiled. When
there is a preceding '+', the feature is included,
when there is a '-' it is excluded. To change this,
you have to edit feature.h and recompile Vim.
To check for this in an expression, see |has()|.
Here is an overview of the features.
The first column shows the smallest version in which
they are included:
T tiny (always)
N normal
H huge
m manually enabled or depends on other features
- never, feature was removed
(none) system dependent
Thus if a feature is marked with "N", it is included
in the normal and huge versions of Vim.

*/dyn* *E370* *E448*
To some of the features "/dyn" is added when the
feature is only available when the related library can
be dynamically loaded.
:ve[rsion] {nr} Is now ignored. This was previously used to check the
version number of a .vimrc file. It was removed,
because you can now use the ":if" command for
version-dependent behavior.
*:redi* *:redir*
:redi[r][!] > {file} Redirect messages to file {file}. The messages which
are the output of commands are written to that file,
until redirection ends. The messages are also still
shown on the screen. When [!] is included, an
existing file is overwritten. When [!] is omitted,
and {file} exists, this command fails.
Only one ":redir" can be active at a time. Calls to
":redir" will close any active redirection before
starting redirection to the new target. For recursive
use check out |execute()|.
To stop the messages and commands from being echoed to
the screen, put the commands in a function and call it
with ":silent call Function()".
An alternative is to use the 'verbosefile' option,
this can be used in combination with ":redir".
:redi[r] >> {file} Redirect messages to file {file}. Append if {file}
already exists.
:redi[r] @{a-zA-Z}
:redi[r] @{a-zA-Z}> Redirect messages to register {a-z}. Append to the
contents of the register if its name is given
uppercase {A-Z}. The ">" after the register name is
optional.
:redi[r] @{a-z}>> Append messages to register {a-z}.
:redi[r] @*>
:redi[r] @+> Redirect messages to the selection or clipboard. For
backward compatibility, the ">" after the register
name can be omitted. See |quotestar| and |quoteplus|.
:redi[r] @*>>
:redi[r] @+>> Append messages to the selection or clipboard.
:redi[r] @"> Redirect messages to the unnamed register. For
backward compatibility, the ">" after the register
name can be omitted.
:redi[r] @">> Append messages to the unnamed register.
*E1092*
:redi[r] => {var} Redirect messages to a variable.
In legacy script: If the variable doesn't exist, then
it is created. If the variable exists, then it is
initialized to an empty string. After the redirection
starts, if the variable is removed or locked or the
variable type is changed, then further command output
messages will cause errors. When using a local
variable (l:var in a function or s:var in a script)
and another `:redir` causes the current one to end,
the scope might be different and the assignment fails.
In Vim9 script: the variable must have been declared
as a string.
The variable will remain empty until redirection ends.
Only string variables can be used.
To get the output of one command the |execute()|
function can be used instead of redirection.
:redi[r] =>> {var} Append messages to an existing variable. Only string
variables can be used.
*E1185*
:redi[r] END End redirecting messages.
*:filt* *:filter*
:filt[er][!] {pattern} {command}
:filt[er][!] /{pattern}/ {command}
Restrict the output of {command} to lines matching
with {pattern}. For example, to list only xml files: >
:filter /\.xml$/ oldfiles
< If the [!] is given, restrict the output of {command}
to lines that do NOT match {pattern}.
{pattern} is a Vim search pattern. Instead of enclosing
it in / any non-ID character (see 'isident') can be
used, so long as it does not appear in {pattern}.
Without the enclosing character the pattern cannot
include the bar character. 'ignorecase' is not used.
The pattern is matched against the relevant part of
the output, not necessarily the whole line. Only some
commands support filtering, try it out to check if it
works. Some of the commands that support filtering:
|:#| - filter whole line
|:clist| - filter by file name or module name
|:command| - filter by command name
|:files| - filter by file name
|:highlight| - filter by highlight group
|:history| - filter by history commands
|:jumps| - filter by file name
|:let| - filter by variable name
|:list| - filter whole line
|:llist| - filter by file name or module name
|:marks| - filter by text in the current file,
or file name for other files
|:oldfiles| - filter by file name
|:registers| - filter by register contents
(does not work multi-line)
|:set| - filter by option name
Only normal messages are filtered, error messages are
not.
*:sil* *:silent* *:silent!*
:sil[ent][!] {command} Execute {command} silently. Normal messages will not
be given or added to the message history.
When [!] is added, error messages will also be
skipped, and commands and mappings will not be aborted
when an error is detected. |v:errmsg| is still set.
When [!] is not used, an error message will cause
further messages to be displayed normally.
Redirection, started with |:redir|, will continue as
usual, although there might be small differences.
This will allow redirecting the output of a command
without seeing it on the screen. Example: >
:redir >/tmp/foobar
:silent g/Aap/p
:redir END
< To execute a Normal mode command silently, use the
|:normal| command. For example, to search for a
string without messages: >
:silent exe "normal /path\<CR>"
< ":silent!" is useful to execute a command that may
fail, but the failure is to be ignored. Example: >
:let v:errmsg = ""
:silent! /^begin
:if v:errmsg != ""
: ... pattern was not found
< ":silent" will also avoid the hit-enter prompt. When
using this for an external command, this may cause the
screen to be messed up. Use |CTRL-L| to clean it up
then.
":silent menu ..." defines a menu that will not echo a
Command-line command. The command will still produce
messages though. Use ":silent" in the command itself
to avoid that: ":silent menu .... :silent command".
*:uns* *:unsilent*
:uns[ilent] {command} Execute {command} not silently. Only makes a
difference when |:silent| was used to get to this
command.
Use this for giving a message even when |:silent| was
used. In this example |:silent| is used to avoid the
message about reading the file and |:unsilent| to be
able to list the first line of each file. >
:silent argdo unsilent echo expand('%') .. ": " .. getline(1)
<
*:verb* *:verbose*
:[count]verb[ose] {command}
Execute {command} with 'verbose' set to [count]. If
[count] is omitted one is used. ":0verbose" can be
used to set 'verbose' to zero.
The additional use of ":silent" makes messages
generated but not displayed.
The combination of ":silent" and ":verbose" can be
used to generate messages and check them with
|v:statusmsg| and friends. For example: >
:let v:statusmsg = ""
:silent verbose runtime foobar.vim
:if v:statusmsg != ""
: " foobar.vim could not be found
:endif
< When concatenating another command, the ":verbose"
only applies to the first one: >
:4verbose set verbose | set verbose
< verbose=4 ~
verbose=0 ~
For logging verbose messages in a file use the
'verbosefile' option.
*:verbose-cmd*
When 'verbose' is non-zero, listing the value of a Vim option or a key map or
an abbreviation or a user-defined function or a command or a highlight group
or an autocommand will also display where it was last defined. If it was
defined manually then there will be no "Last set" message. When it was
defined while executing a function, user command or autocommand, the script in
which it was defined is reported.
{not available when compiled without the |+eval| feature}
*K*
K Run a program to lookup the keyword under the
cursor. The name of the program is given with the
'keywordprg' (kp) option (default is "man"). The
keyword is formed of letters, numbers and the
characters in 'iskeyword'. The keyword under or
right of the cursor is used. The same can be done
with the command >
:!{program} {keyword}
< There is an example of a program to use in the tools
directory of Vim. It is called "ref" and does a
simple spelling check.
Special cases:
- If 'keywordprg' begins with ":" it is invoked as
a Vim Ex command with [count].
- If 'keywordprg' is empty, the ":help" command is
used. It's a good idea to include more characters
in 'iskeyword' then, to be able to find more help.
- When 'keywordprg' is equal to "man" or starts with
":", a [count] before "K" is inserted after
keywordprg and before the keyword. For example,
using "2K" while the cursor is on "mkdir", results
in: >
!man 2 mkdir
< - When 'keywordprg' is equal to "man -s", a count
before "K" is inserted after the "-s". If there is
no count, the "-s" is removed.
*v_K*
{Visual}K Like "K", but use the visually highlighted text for
the keyword. Only works when the highlighted text is
not more than one line.
[N]gs *gs* *:sl* *:sleep*
:[N]sl[eep] [N][m] Do nothing for [N] seconds. When [m] is included,
sleep for [N] milliseconds. The count for "gs" always
uses seconds. The default is one second. >
:sleep "sleep for one second
:5sleep "sleep for five seconds
:sleep 100m "sleep for 100 milliseconds
10gs "sleep for ten seconds
< Can be interrupted with CTRL-C (CTRL-Break on
MS-Windows). "gs" stands for "goto sleep".
While sleeping the cursor is positioned in the text,
if at a visible position.
Queued messages and timers (|+timers|) are processed
during the sleep as well.
*:sl!* *:sleep!*
:[N]sl[eep]! [N][m] Same as above, but hide the cursor.
*:xrestore* *:xr*
:xr[estore] [display] Reinitializes the connection to the X11 server. Useful
after the X server restarts, e.g. when running Vim for
long time inside screen/tmux and connecting from
different machines.
[display] should be in the format of the $DISPLAY
environment variable (e.g. "localhost:10.0")
If [display] is omitted, then it reinitializes the
connection to the X11 server using the same value as
was used for the previous execution of this command.
If the value was never specified, then it uses the
value of $DISPLAY environment variable as it was when
Vim was started. This will also update |v:clipmethod|.
{only available when compiled with the
|+xterm_clipboard| feature}
*:clipreset* *:clip*
:clip[reset] Attempts to choose a new method for accessing the
clipboard, using the 'clipmethod' option. This is
useful when the current method has become unavailable,
and you want to try using another method.
{only available when compiled with the |+clipboard|
feature}
*g_CTRL-A*
g CTRL-A Only when Vim was compiled with MEM_PROFILING defined
(which is very rare): print memory usage statistics.
Only useful for debugging Vim.
For incrementing in Visual mode see |v_g_CTRL-A|.
==============================================================================
2. Using Vim like less or more *less*
If you use the less or more program to view a file, you don't get syntax
highlighting. Thus you would like to use Vim instead. You can do this by
using the shell script "$VIMRUNTIME/macros/less.sh".
This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim". It sets
up mappings to simulate the commands that less supports. Otherwise, you can
still use the Vim commands.
This isn't perfect. For example, when viewing a short file Vim will still use
the whole screen. But it works well enough for most uses, and you get syntax
highlighting.
The "h" key will give you a short overview of the available commands.
If you want to set options differently when using less, define the
LessInitFunc in your vimrc, for example: >
func LessInitFunc()
set nocursorcolumn nocursorline
endfunc
