Managing your Environment

Your working environment is defined whenever you login or start another shell. This environment is set using the values that the shell finds in initialisation files which it always reads as it starts up.

You can change your working environment by editing these files and setting new values for variables. Each shell handles its initialisation files in a different way; select one of the headings below for the shell that you use.
