How to exit a BASH script

Pete-Ratcliffe · 09-03-2009, 06:36 AM

Greetings,

I have a script that checks for the existence of a file and, if this file doesn't exist, I want the script to output a message to the screen then terminate.

This is all fairly simple and I've got a solution that works, only problem is, when the script terminates, it closes my PuTTY session!

Below is the code I'm using:

Quote:

if [ ! -e _Settings.sh ] ; then
echo "Unable to find _Settings.sh!"
echo ""
read prompt?'Please create _Settings.sh before continuing. Press any key to continue . . .'
exit
fi

Is there an alternative to 'exit' so my session can remain open? I know I could expand the if clause with an else but that just seems a bit overkill imo.

Thanks in advance!

Sounds like you're sourcing the file, instead of just executing it.

Code:

# sourcing:
. ./script.sh

# executing
./script.sh

You're absolutely correct! Thanks
