Add colour to grep

It can be quite useful to add colour to your output from grep, since it helps is identifying matches and hence makes sure you do not overlook something.

Basic example:

$ grep --color <pattern> <file>

Default colour is red, but can be changes using the environment variable GREP_COLOR:

An example:

$ GREP_COLOR='1;36' grep --color <pattern> <file>

I have only used two parameters in the above example, You can in addition set the background colour, please see the listed source for more details.
