As many here, I'm a developer and I work across multiple tech stacks. At some point became bored with typing and remembering lengthy commands for building, testing etc. So I wrote a little command line tool that allows me to instead write ez build or ez test or similar regardless of the tech stack the repo is based on (not magically, but by storing them once).

I added a bonus function where ez outputs also the time it took to run the subprocess, this is pretty nice for keeping an eye on build times and unit test run times without even thinking about it. Running commands in parallel as separate subprocesses is also supported.
