If you used a Raspberry Pi, where you probably run Raspian/Debian Linux, you’ll notice that is has a colorful prompt:
This shows who you are currently logged-in-as, and the computer name in green, then the directory where you are in blue. On a screen with grey-on-black text, it helps make the screen more readable.
You might be slightly annoyed that this isn’t enabled in many other Linux distributions. However, “enabled” is the keyword. For systems that default to using the bash shell, you should see a .bashrc file in your home directory – edit that:
$ nano ~./.bashrc
in that file, hopefully you see some sections at the end refering to “$color_prompt”, etc. If so, look just above there for:
and uncomment that (take away the hash sign). Voila, you now have that easy-to-read color prompt like you have on the Raspberry Pi.
If you don’t have a .bashrc or those default color settings, as a reference, here is the .bashrc from Raspian.
