Use return instead of exit when you have an error and you're sourcing
the script. You can make it conditional.
Try setting OPTIND=1 to make your script work when it's sourced.
Initialize your script's variables since they will be carried over
between runs when you source the script.
#!/bin/bash
invoked=$_ # needs to be first thing in the script
OPTIND=1 # also remember to initialize your flags and other variables
. . . # do some stuff
if some error condition
then
if [[ $invoked != $0 ]]
then
return 1 # the script was sourced
else
exit 1 # the script was executed
fi
fi
