There is a subset of shell commands that I run infrequently enough to forget them but frequently enough for the searching time to accumulate. I did use Anki for those until I switched to infinite bash history. So I guess that there is a sweet spot between one-offs and frequent things where SRS can help (but there are other solutions too).
