Maintain text colors when wrapping command in bash script

Question

So I've made a small script to search through my project for a word:

#!/bin/bash
grep -n $1 js/*/**.js
grep -n $1 js/*.js

When running these commands in the command line I will get some nice syntax highlighting. But when I run them in a script I loose the colors. How can avoid this?

Answer 1

This will do the trick, the --color flag takes care of coloured output. In your shell it is probably aliased.

#!/bin/bash
grep --color -n $1 js/*/**.js
grep --color -n $1 js/*.js

Answer 2

Set these environment variables:

GREP_OPTIONS=--color=auto
GREP_COLOR=1;32

Where 1;32 is the color code for light green. You can change the color of highlighting using another code: http://hacktux.com/bash/colors.
