I comment the commands that I want and then use vim to remove ones without comments.
For example, I run:
longandannoyingcommand -f1 -f2 -f3 # keep, does something useful
Usually comment explains what the command does so I can find it by description using fzf history search.
And then you can easily find all lines that contain (or do not contain “# keep”) in your history to remove or keep.
