Get Ruby Exit Script Early Pics. Ruby lets you register handlers which can be called whenever the program exits. We should be very conscious of how our program exits, not because we display an error it means the script is reporting that it finished with an error.
If exit codes are not set the exit code will be the exit code to set an exit code in a script use exit 0 where 0 is the number you want to return.
We recently had a problem to solve which at its core required us to iterate through a collection, look up a value for each key and then exit as soon as we'd found a value. However it is worth a mention here. It exits early using kernel.exit if a match is found. Every time you enter an irb session, boot a ruby script, or run a test runner you're starting up a process.
