comparison .bashrc @ 14:94cfcec3b5b6
When bash is called non-interactively, PS1 is unset. However, if it's a login
shell, ~/.bash_profile is still sourced. Therefore, testing PS1 tells us if
this is a login but non-interactive shell (such as: ssh host 'uptime').
Testing PS1 before setting it preserves that state for later tests if desired.
