A cat(1) clone with syntax highlighting and Git integration.
Usage: bat [OPTIONS] [FILE]...
bat <COMMAND>
Arguments:
[FILE]...
File(s) to print / concatenate. Use a dash ('-') or no argument at all to read from
standard input.
Options:
-A, --show-all
Show non-printable characters like space, tab or newline. This option can also be used to
print binary files. Use '--tabs' to control the width of the tab-placeholders.
--nonprintable-notation <notation>
Set notation for non-printable characters.
Possible values:
* unicode (␇, ␊, ␀, ..)
* caret (^G, ^J, ^@, ..)
--binary <behavior>
How to treat binary content. (default: no-printing)
Possible values:
* no-printing: do not print any binary content
* as-text: treat binary content as normal text
-p, --plain...
Only show plain style, no decorations. This is an alias for '--style=plain'. When '-p' is
used twice ('-pp'), it also disables automatic paging (alias for '--style=plain
--paging=never').
-l, --language <language>
Explicitly set the language for syntax highlighting. The language can be specified as a
name (like 'C++' or 'LaTeX') or possible 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
'--highlight-line 30:+10' highlights lines 30 to 40
--file-name <name>
Specify the name to display for a file. Useful when piping data to bat from STDIN when bat
does not otherwise know the filename. Note that the provided file name is also used for
syntax detection.
-d, --diff
Only show lines that have been added/removed/modified with respect to the Git index. Use
--diff-context=N to control how much context you want to see.
--diff-context <N>
Include N lines of context around added/removed/modified lines when using '--diff'.
--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.
-S, --chop-long-lines
Truncate all lines longer than screen width. Alias for '--wrap=never'.
--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 enables colors if an
interactive terminal is detected - colors are automatically disabled if the output goes to
a pipe.
Possible values: *auto*, never, always.
--italic-text <when>
Specify when to use ANSI sequences for italic text in the output. 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 interactive 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 --paging=never' or its
alias,'-P'. To disable the pager permanently, set BAT_PAGING to 'never'. 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:syntax>
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'. Note that the right-hand side is the *name* of the syntax, not
a file extension.
--ignored-suffix <ignored-suffix>
Ignore extension. For example:
'bat --ignored-suffix ".dev" my_file.json.dev' will use JSON syntax, and ignore '.dev'
--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="...").
Special values:
* auto: Picks a dark or light theme depending on the terminal's colors (default).
Use '--theme-light' and '--theme-dark' to customize the selected theme.
* auto:always: Detect the terminal's colors even when the output is redirected.
* auto:system: Detect the color scheme from the system-wide preference (macOS only).
* dark: Use the dark theme specified by '--theme-dark'.
* light: Use the light theme specified by '--theme-light'.
--theme-light <theme>
Sets the theme name for syntax highlighting used when the terminal uses a light
background. Use '--list-themes' to see all available themes. To set a default theme, add
the '--theme-light="..." option to the configuration file or export the BAT_THEME_LIGHT
environment variable (e.g. export BAT_THEME_LIGHT="...").
--theme-dark <theme>
Sets the theme name for syntax highlighting used when the terminal uses a dark background.
Use '--list-themes' to see all available themes. To set a default theme, add the
'--theme-dark="..." option to the configuration file or export the BAT_THEME_DARK
environment variable (e.g. export BAT_THEME_DARK="...").
--list-themes
Display a list of supported themes for syntax highlighting.
-s, --squeeze-blank
Squeeze consecutive empty lines into a single empty line.
--squeeze-limit <squeeze-limit>
Set the maximum number of consecutive empty lines to be printed.
--strip-ansi <when>
Specify when to strip ANSI escape sequences from the input. The automatic mode will remove
escape sequences unless the syntax highlighting language is plain text. Possible values:
auto, always, *never*.
--style <components>
Configure which elements (line numbers, file headers, grid borders, 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="..").
When styles are specified in multiple places, the "nearest" set of styles take precedence.
The command-line arguments are the highest priority, followed by the BAT_STYLE environment
variable, and then the configuration file. If any set of styles consists entirely of
components prefixed with "+" or "-", it will modify the previous set of styles instead of
replacing them.
By default, the following components are enabled:
changes, grid, header-filename, numbers, snip
Possible values:
* default: enables recommended style components (default).
* full: enables all available components.
* auto: same as 'default', unless the output is piped.
* plain: disables all available components.
* changes: show Git modification markers.
* header: alias for 'header-filename'.
* header-filename: show filenames before the content.
* header-filesize: show file sizes before the content.
* grid: vertical/horizontal lines to separate side bar
and the header from the content.
* rule: horizontal lines to delimit files.
* numbers: show line numbers in the side bar.
* snip: draw separation lines between distinct line ranges.
-r, --line-range <N:M>
Only print the specified range of lines for each file. For example:
'--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
'--line-range 40' only prints line 40
'--line-range 30:+10' prints lines 30 to 40
-L, --list-languages
Display a list of supported languages for syntax highlighting.
-u, --unbuffered
This option exists for POSIX-compliance reasons ('u' is for 'unbuffered'). The output is
always unbuffered - this option is simply ignored.
--diagnostic
Show diagnostic information for bug reports.
--acknowledgements
Show acknowledgements.
--set-terminal-title
Sets terminal title to filenames when using a pager.
-h, --help
Print help (see a summary with '-h')
-V, --version
Print version
