Ubuntu – Displaying colors in the prompt

Found an easy way to do it:

Uncomment force_color_prompt=yes in ~/.bashrc.

You can edit the settings editing the file: ~/.bashrc.

1. Open the file: gedit ~/.bashrc.

2. Look for the line with #force_color_prompt=yes and uncomment (delete the #).

3. Look for the line below if [ "$color_prompt" = yes ]; then that should looks like:

   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
   

   Pay attention at the part \u@\h it is saying "user@host" and the number before it \[\033[01;32m\] indicates the color. This is what you have to change. For example, lets change the user to purple, the "@" to black and host to green. Edit the line so it looks like:

   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;35m\]\u\[\033[01;30m\]@\[\033[01;32m\]\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
   

Result:

The colors numbers are:

Black       0;30     Dark Gray     1;30
Blue        0;34     Light Blue    1;34
Green       0;32     Light Green   1;32
Cyan        0;36     Light Cyan    1;36
Red         0;31     Light Red     1;31
Purple      0;35     Light Purple  1;35
Brown       0;33     Yellow        1;33
Light Gray  0;37     White         1;37
