1.
Regarding "Quitting a bash script": The thread is closed so I couldn't post there, but I did want to share this.


Code:
      exit


exits the shell, which is usually not what you want if the script was
Code:

source


d.

An alternative is to use
Code:
      kill -SIGINT $$


which sends an interrupt to the shell process (whose pid is stored in the $$ variable).

You can also use this test to determine if a bash script is being run sourced or was run as its own command:


Code:
x"${BASH_SOURCE[0]}" == x"$0"

If this is true, then it isn't sourced, if it's false (the scriptname is not $0) it was sourced.
