Easily colorize commands output using patterns.

rainbow [ --COLOR=PATTERN ... | --conf CONF ] COMMAND

Prepend rainbow with --COLOR=PATTERN associations to your command, for example:

• Tail some log file with lines containing ERROR in red:

  rainbow --red=ERROR tail -f /var/log/my.log
  

• You can also pipe commands output into rainbow:

  tail -f /var/log/my.log | rainbow --red=ERROR
  

Rainbow can load configuration for each command from files, which is the most convenient way to use it. When running rainbow mycommand, rainbow will automatically look for a config named mycommand.cfg in ~/.config/rainbow, ~/.rainbow, /etc/rainbow, or builtin configs:

• Colorize the diff command output using the builtin config:

  rainbow diff file1 file2
  

• Start my custom command, using ~/.rainbow/mycommand.cfg:

  rainbow mycommand
  

The syntax for writing configs is straightforward, see the builtin configs for examples. See also the commands support table.

You can build from sources this way:

git clone git://github.com/nicoulaj/rainbow.git
cd rainbow
python setup.py build install --user
