- Do not set the PS1 if it is not set already (which means that, if the shell is not interactive). Just testing to see if the PS1 is “non-empty” is a common way to find out if the shell is interactive or not and we don’t want to confuse programs that do that (that means a more accurate test is checking to see if $- contains i).
- If you want this code to run when you are logging into a remote server, you should have one of these profile files always source ~/.bashrc (Here I am assuming you already know that).
- In PS1, the escape codes must be enclosed with in […].
-
[033[m resets the foreground and background to their default values, so here:w appears in the terminal background/foreground.
-
[033[48;5;XXXm 33[38;5;YYYm sets background/foreground to XXX/YYY.
- For a script that dumps the available colors, try colortest.
- To check and see what the Bash Prompt would look like, use the: echo -e “< 33[48;5;16m 33[38;5;196mhost 33[m:dir>$ “
