When exit is called, the shell will exit, regardless of any traps that have been set.

The most palatable workaround that comes to mind:
Code:
exit() { :;}
source other_file
unset -f exit


Aliasing may also be an option, but the following will most likely fail unless the shell is in interactive mode or a sh option specifiying expansion of aliases in non-interactive mode is enabled.
Code:
alias exit=:
source other_file
unalias exit

Either solution will evaluate exit's args, so if they have side effects those effects will occur (though this seems to me unlikely with an exit command).

Regards,
Alister

If the only occurrence of "exit" in the script is as a command name, then you can also do the following:
Code:
eval "$(sed 's/exit/:/g' other_file)"

If exit only occurs on a line by itself:
Code:
eval "$(sed '/exit/d' other_file)"
