Cron expressions aren't bad. Now regex.... nope.

For some reason regex just clicked for me very easily. Granted, I use regexr.com to check my work and tune it, but I find that the syntax just makes sense when I know what I want to find.

I can't even remember tar or find options reliably.

The only tar command I can remember reliably is this one:

    tar -tf ./archive.tar

It lists all of the files in the archive. I only remember it because of the mnemonic "tar the fuck is in this archive."

    journalctl -fu some-service

Also feels appropriate, because most of the time when I have to type in that command I'm thinking FU service file for not showing me by default why a service failed to start/restart.

Try tldr find or tldr tar for examples. Use fzf on history to find past success. Consider a toollike ouch [1] or fd instead of find.
