I do the opposite and maybe weird - I disable history, and keep the history file contents hand curated. Whenever I come up/across/use a command I'd like to keep for future or use frequently, it gets appended to the history file.

Do you use the fc command (shell builtin in the case of bash) to access the history? Or just up-arrow to scroll through the options?

Ctrl+R (reverse fuzzy lookup) -- In my early days, I quickly found it very annoying to have to scroll through garbage to get to the command I want.

Do you have an alias or something else that facilitates that, or do you just do it manually?

Never bothered to fully automate it, tbh.

I use `unset HISTFILE` to make sure when I exit the history file doesn't get all the cruft in. Every now and then I might do some housecleaning, including going through the history file then `cp ~/.bash_history{,.2}` to keep a clean copy around.

As far as saving, heres a handy function: `getlast() { fc -ln "$1" "$1" | sed '1s/^[[:space:]]*//' }`
