try 🚀

try is a command line utility to try executing a shell command and retry if it fails. Optionally, you can let it repeat even if it succeeds.

You run a long running command and leave to grab a ☕️, hoping to come back to a completed execution but you come back to find that the process failed due to a connectivity issue which is now fixed 🎩. You are now left to re-run the process and spend several caffeine-powered minutes staring at your terminal. Never again!

Usage

Use the try keyword.

-a, --attempts <number>  => Maximum number of retry attempts.
