Colorize

The command line with colors looks so pretty!

grep

Use the argument –color:

grep --color=auto

The options are:

• auto: doesn’t colorize if the output is a pipe.
• always
• never

less / more

Use the argument -R (or -r):

more -r

Example colorize grep output:

rgrep --color=auto TODO . | more -r

pygmentize

pygmentize colorizes the input allowing different lexers:

pygmentize [-l lexer] [file]

The lexer will be autodected, but if not some of the lexers are:

• rst: reStructuredText
• html
• python
