Question

I have set some variables in my shell, because I need them all the time. How can I make a script, that I call on the same shell that has variables set access the variables that are defined in the shell, without passing them explicitely as parameters?

Answer 1

You simply source the script with the assignments in your shell script like so:

 . /path/to/settings  # Dot, blank, name of file.

This will execute the contents of settings in the current shell (as opposed to starting a subshell, where assignments are lost after the subshell ends.)
