PS1 variable
 
Just what is the PS1 shell variable and what does it do? I know when I modify it the command prompt changes, but I'm not sure.

PS1 stands for "prompt string 1" and defines the primary prompt string.

Kind regards

If you don't know what a prompt string is, it is usually a $ or bash-4.1$, see:

Okay, thank you. How come the variable doesn't end up in the env or export listings then?

It is in 'set', which shows more than those.
