Colorize commands output or STDIN using patterns
Rainbow allows you to colorize commands output or STDIN using patterns. This is a fork of Linibou's colorex.

Installing

ArchLinux

rainbow is available in AUR.

Building from sources

You can build from sources this way:

git clone git://github.com/nicoulaj/rainbow.git
cd rainbow
sudo python setup.py install


Getting started

After installing the package, call the help to get started:

rainbow --help

Main features:

  • Rainbow colors parts of commands output or STDIN using words or regexps. Just prepend rainbow with patternscolors 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
  • Ping Google with IP addresses colorized in yellow:
  • rainbow --yellow '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}' -- ping www.google.com
  • Rainbow can also read from STDIN instead of providing a command:
  • tail -f /var/log/my.log | rainbow --red '.*ERROR.*'
  • Rainbow can read patternscolors associations from config files, which is the most common way to use it. It automatically uses the config file if there is one named after the command name. Rainbow comes bundled with several configs for common commands:
  • Colorize the 'diff' command output using the provided config:
  • rainbow diff file1 file2
  • Start JBoss application server with colorized logs:
  • rainbow --config=jboss -- jboss/bin/run.sh run
  • See man rainbow for details on how using config files and writing your own ones.
