BAT(1) General Commands Manual BAT(1)
|
||
|
||
NAME
|
||
bat - a cat(1) clone with syntax highlighting and Git integration.
|
||
|
||
USAGE
|
||
bat [OPTIONS] [FILE]...
|
||
|
||
bat cache [CACHE-OPTIONS] [--build|--clear]
|
||
|
||
DESCRIPTION
|
||
bat prints the syntax-highlighted content of a collection of FILEs to
|
||
the terminal. If no FILE is specified, or when FILE is '-', it reads
|
||
from standard input.
|
||
|
||
bat supports a large number of programming and markup languages. It
|
||
also communicates with git(1) to show modifications with respect to the
|
||
git index. bat automatically pipes its output through a pager (by de‐
|
||
fault: less).
|
||
|
||
Whenever the output of bat goes to a non-interactive terminal, i.e.
|
||
when the output is piped into another process or into a file, bat will
|
||
act as a drop-in replacement for cat(1) and fall back to printing the
|
||
plain file contents.
|
||
|
||
OPTIONS
|
||
General remarks: Command-line options like '-l'/'--language' that take
|
||
values can be specified as either '--language value', '--lan‐
|
||
guage=value', '-l value' or '-lvalue'.
|
||
|
||
-A, --show-all
|
||
|
||
Show non-printable characters like space, tab or newline. Use
|
||
'--tabs' to control the width of the tab-placeholders.
|
||
|
||
-p, --plain
|
||
|
||
Only show plain style, no decorations. This is an alias for
|
||
'--style=plain'. When '-p' is used twice ('-pp'), it also dis‐
|
||
ables automatic paging (alias for '--style=plain
|
||
--pager=never').
|
||
|
||
-l, --language <language>
|
||
|
||
Explicitly set the language for syntax highlighting. The lan‐
|
||
guage can be specified as a name (like 'C++' or 'LaTeX') or pos‐
|
||
sible file extension (like 'cpp', 'hpp' or 'md'). Use
|
||
'--list-languages' to show all supported language names and file
|
||
extensions.
|
||
|
||
-H, --highlight-line <N:M>...
|
||
|
||
Highlight the specified line ranges with a different background
|
||
color For example:
|
||
|
||
--highlight-line 40
|
||
highlights line 40
|
||
|
||
--highlight-line 30:40
|
||
highlights lines 30 to 40
|
||
|
||
--highlight-line :40
|
||
highlights lines 1 to 40
|
||
|
||
--highlight-line 40:
|
||
highlights lines 40 to the end of the file
|
||
|
||
--tabs <T>
|
||
|
||
Set the tab width to T spaces. Use a width of 0 to pass tabs
|
||
through directly
|
||
|
||
--wrap <mode>
|
||
|
||
Specify the text-wrapping mode (*auto*, never, character). The
|
||
'--terminal-width' option can be used in addition to control the
|
||
output width.
|
||
|
||
--terminal-width <width>
|
||
|
||
Explicitly set the width of the terminal instead of determining
|
||
it automatically. If prefixed with '+' or '-', the value will be
|
||
treated as an offset to the actual terminal width. See also:
|
||
'--wrap'.
|
||
|
||
-n, --number
|
||
|
||
Only show line numbers, no other decorations. This is an alias
|
||
for '--style=numbers'
|
||
|
||
--color <when>
|
||
|
||
Specify when to use colored output. The automatic mode only en‐
|
||
ables colors if an interactive terminal is detected. Possible
|
||
values: *auto*, never, always.
|
||
|
||
--italic-text <when>
|
||
|
||
Specify when to use ANSI sequences for italic text in the out‐
|
||
put. Possible values: always, *never*.
|
||
|
||
--decorations <when>
|
||
|
||
Specify when to use the decorations that have been specified via
|
||
'--style'. The automatic mode only enables decorations if an in‐
|
||
teractive terminal is detected. Possible values: *auto*, never,
|
||
always.
|
||
|
||
-f, --force-colorization
|
||
|
||
Alias for '--decorations=always --color=always'. This is useful
|
||
if the output of bat is piped to another program, but you want
|
||
to keep the colorization/decorations.
|
||
|
||
--paging <when>
|
||
|
||
Specify when to use the pager. To disable the pager, use '--pag‐
|
||
ing=never' or its alias, -P. To disable the pager permanently,
|
||
set BAT_PAGER to an empty string. To control which pager is
|
||
used, see the '--pager' option. Possible values: *auto*, never,
|
||
always.
|
||
|
||
--pager <command>
|
||
|
||
Determine which pager is used. This option will override the
|
||
PAGER and BAT_PAGER environment variables. The default pager is
|
||
'less'. To control when the pager is used, see the '--paging'
|
||
option. Example: '--pager "less -RF"'.
|
||
|
||
-m, --map-syntax <glob-pattern:syntax-name>...
|
||
|
||
Map a glob pattern to an existing syntax name. The glob pattern
|
||
is matched on the full path and the filename. For example, to
|
||
highlight *.build files with the Python syntax, use -m
|
||
'*.build:Python'. To highlight files named '.myignore' with the
|
||
Git Ignore syntax, use -m '.myignore:Git Ignore'.
|
||
|
||
--theme <theme>
|
||
|
||
Set the theme for syntax highlighting. Use '--list-themes' to
|
||
see all available themes. To set a default theme, add the
|
||
'--theme="..."' option to the configuration file or export the
|
||
BAT_THEME environment variable (e.g.: export BAT_THEME="...").
|
||
|
||
--list-themes
|
||
|
||
Display a list of supported themes for syntax highlighting.
|
||
|
||
--style <style-components>
|
||
|
||
Configure which elements (line numbers, file headers, grid bor‐
|
||
ders, Git modifications, ..) to display in addition to the file
|
||
contents. The argument is a comma-separated list of components
|
||
to display (e.g. 'numbers,changes,grid') or a pre-defined style
|
||
('full'). To set a default style, add the '--style=".."' option
|
||
to the configuration file or export the BAT_STYLE environment
|
||
variable (e.g.: export BAT_STYLE=".."). Possible values: *auto*,
|
||
full, plain, changes, header, grid, numbers, snip.
|
||
|
||
-r, --line-range <N:M>...
|
||
|
||
Only print the specified range of lines for each file. For exam‐
|
||
ple:
|
||
|
||
--line-range 30:40
|
||
prints lines 30 to 40
|
||
|
||
--line-range :40
|
||
prints lines 1 to 40
|
||
|
||
--line-range 40:
|
||
prints lines 40 to the end of the file
|
||
|
||
-L, --list-languages
|
||
|
||
Display a list of supported languages for syntax highlighting.
|
||
|
||
-u, --unbuffered
|
||
|
||
This option exists for POSIX-compliance reasons ('u' is for 'un‐
|
||
buffered'). The output is always unbuffered - this option is
|
||
simply ignored.
|
||
|
||
-h, --help
|
||
|
||
Print this help message.
|
||
|
||
-V, --version
|
||
|
||
Show version information.
|
||
|
||
POSITIONAL ARGUMENTS
|
||
<FILE>...
|
||
|
||
Files to print and concatenate. Use a dash ('-') or no argument
|
||
at all to read from standard input.
|
||
|
||
SUBCOMMANDS
|
||
cache - Modify the syntax-definition and theme cache.
|
||
|
||
FILES
|
||
bat can also be customized with a configuration file. The location of
|
||
the file is dependent on your operating system. To get the default path
|
||
for your system, call:
|
||
|
||
bat --config-file
|
||
|
||
Alternatively, you can use the BAT_CONFIG_PATH environment variable to
|
||
point bat to a non-default location of the configuration file.
|
||
|
||
ADDING CUSTOM LANGUAGES
|
||
bat supports Sublime Text .sublime-syntax language files, and can be
|
||
customized to add additional languages to your local installation. To
|
||
do this, add the .sublime-snytax language files to `$(bat --config-
|
||
dir)/syntaxes` and run `bat cache --build`.
|
||
|
||
Example:
|
||
|
||
mkdir -p "$(bat --config-dir)/syntaxes"
|
||
cd "$(bat --config-dir)/syntaxes"
|
||
|
||
# Put new '.sublime-syntax' language definition files
|
||
# in this folder (or its subdirectories), for example:
|
||
git clone https://github.com/tellnobody1/sublime-purescript-syntax
|
||
|
||
# And then build the cache.
|
||
bat cache --build
|
||
|
||
Once the cache is built, the new language will be visible in `bat
|
||
--list-languages`.
|
||
If you ever want to remove the custom languages, you can clear the
|
||
cache with `bat cache --clear`.
|
||
|
||
ADDING CUSTOM THEMES
|
||
Similarly to custom languages, bat supports Sublime Text .tmTheme
|
||
themes. These can be installed to `$(bat --config-dir)/themes`, and
|
||
are added to the cache with `bat cache --build`.
