bat/doc/long-help.txt

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, ^@, ..)

  -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
