By default, none of the following files may be present on your account, and you will get the default settings for the system. However, you may want to customise your environment to add new variables, functions or aliases to your sessions or jobs.
| File | When is it is sourced? | Who sources it? | What is it for? |
|---|---|---|---|
$HOME/.profile | each login and job execution | Bash and ksh | Suitable for your own login session settings (e.g. PATH). |
$HOME/.bash_profile | each bash login and job execution | Bash only | Suitable for your own login session settings that must only run once for the session or job (e.g. PATH). It overrides .profile if present |
$HOME/.bashrc | each bash interactive non-login shell | Bash only | Suitable for your own functions and aliases to load for interactive non-login sessions. It is not loaded automatically on login sessions |
$HOME/.bash_logout | each bash exit and end of job | Bash only | Suitable for your own cleanup settings at the end of the session or job |
$HOME/.kshrc | each ksh login and job execution | ksh only | Suitable for your own settings to load for interactive shells |
