backup script early termination

onthefritz · 06-16-2008, 09:06 AM

I am writing a backup script and I would like to find a way (for error checking) to terminate the script early. I am using an if statement to check to see if /backup if a file instead of a directory. If it is, then I just want to terminate the script. That would keep me from wrapping the script in an if statement. Here is the if statement I am using:

Code:

    if [ -a /backup ];
    then
    echo "Warning: /backup is a file, not a directory"
    # here is where I want to terminate the script
    fi

So can anyone help me out?

Thanks

Code:

if [ -a /backup ];
then
    echo "Warning: /backup is a file, not a directory"
    exit 1 # it is convention to exit with a non-zero exit status to indicate failure
fi

Thanks, I wont know how well it works until I can run some test though. I don't doubt that it will work.
