Also the while; do; loop could probably be replaced with 'watch'.
Though I'll admit to occasional traumatic moments when my workstation crashes and bash history is polluted with multiple shells filling it and the stuff I've been ctrl-R invoking (recursive reverse search) for months evaporates.
The problem is curation.
It's really handy to have stuff in history. But there's a ton of crap I don't need.
What I need to do is get better about scripting the stuff that I'm invoking frequently. Though zsh probably has an extension that does this for you, and scratches your back.
Mind: virtually all my shell scripts start off as one-liners that I've invoked and re-edited (M-x M-e FTFW) until I've realized I have something worth saving.
Or making your history permanent. I have a reasonable sized history in my shell, but also dump out each line I typed to an eternal history file.
