Here you go. It also checks if you're root. Save it as something |
| 30 |
suitable somewhere in your $PATH, (e.g. ~/bin/bash_prompt), modify to |
| 31 |
suit your setup, then do: |
| 32 |
|
| 33 |
source ~/bin/bash_prompt |
| 34 |
colour_code_prompt |
| 35 |
unset colour_code_prompt |
| 36 |
|
| 37 |
either from the shell or in your .bashrc to load it. |
| 38 |
|
| 39 |
Use at your own risk, since I've only just written it, and haven't |
| 40 |
tested it very heavily! (When I've used it a bit to check it works |
| 41 |
properly, I might document it a bit and put it on my web site.) |
