NAME

exa_colors — customising the file and UI colours of exa

SYNOPSIS

The EXA_COLORS environment variable can be used to customise the colours that exa uses to highlight file names, file metadata, and parts of the UI.

You can use the dircolors program to generate a script that sets the variable from an input file, or if you don’t mind editing long strings of text, you can just type it out directly. These variables have the following structure:

  • A list of key-value pairs separated by `===’, such as `=*.txt=32=’.
  • Multiple ANSI formatting codes are separated by `=;=’, such as `=*.txt=32;1;4=’.
  • Finally, multiple pairs are separated by `=:=’, such as `=*.txt=32:*.mp3=1;35=’.

The key half of the pair can either be a two-letter code or a file glob, and anything that’s not a valid code will be treated as a glob, including keys that happen to be two letters long.

EXAMPLES

EXA_COLORS“uu=0:gu=0”=
Disable the “current user” highlighting
EXA_COLORS“da=32”=
Turn the date column green
EXA_COLORS“Vagrantfile=1;4;33”=
Highlight Vagrantfiles
EXA_COLORS.zip=38;5;125“=*
Override the existing zip colour
EXA_COLORS.md=38;5;121:*.log=38;5;248“=*
Markdown files a shade of green, log files a shade of grey

sb
the units of a file’s size (sets ub, uk, um, ug and uh)
ub
the units of a file’s size if it is lower than 1 KB/Kib
uk
the units of a file’s size if it is between 1 KB/KiB and 1 MB/MiB
um
the units of a file’s size if it is between 1 MB/MiB and 1 GB/GiB
ug

bl
a file’s number of blocks
hd
the header row of a table
lp
the path of a symlink
cc
an escaped character in a filename
bO
the overlay style for broken symlink paths

Values in EXA_COLORS override those given in LS_COLORS, so you don’t need to re-write an existing LS_COLORS variable with proprietary extensions.

LIST OF STYLES

Unlike some versions of ls, the given ANSI values must be valid colour codes: exa won’t just print out whichever characters are given.

The codes accepted by exa are:

1
for bold
4
for underline
31
for red text
32
for green text
33
for yellow text
34
for blue text
35
for purple text
36
for cyan text
37
for white text
38;5;nnn
for a colour from 0 to 255 (replace the nnn part)

Many terminals will treat bolded text as a different colour, or at least provide the option to.

exa provides its own built-in set of file extension mappings that cover a large range of common file extensions, including documents, archives, media, and temporary files. Any mappings in the environment variables will override this default set: running exa with LS_COLORS“*.zip=32”= will turn zip files green but leave the colours of other compressed files alone.

You can also disable this built-in set entirely by including a reset entry at the beginning of EXA_COLORS. So setting EXA_COLORS“reset:*.txt=31”= will highlight only text files; setting EXA_COLORS“reset”= will highlight nothing.
