Ask HN: Secret options or commands for popular programs?

3 points by solarmist ↗ HN
The SSH tools link made me think of little known commands or options to tools I use all the time.

Like suspending an active ssh connection (”~ ctrl-z”).

What other ones have people learned and then thought, “I wish I had known this all along. “

What is that? I haven't heard of it.

Unsure if it’s a bash feature, but press ctrl+r on the cli

The interactive arg/string you type matches, against your history, to the most recent cmd that contains the string

Oh, yeah. I use that all the time. Just never hear it called that.
