[LU-12734] bash completion (for now: lctl set/get_param)

Related — Tue, 13 Dec 2022 18:01:03 +0000

Fairly far from lustre itself... Being used to tabbing into /proc/fs/lustre, with many files moving to various subdirectories of /sys the lctl set/get_param commands are really hard to use for me without completion.

I wrote bash completion for the *_param commands only to start with, will push to gerrit what I have right away.

Questions:

is there interest in general? If not, close this and will spare my time as well
can we land some partial completion (e.g. right now the first level of tab works with --list-commands, but beyond that you're on your own except for params commands), or do we want something complete-ish from the start?
if we start with lctl, what about lfs, lnetctl, etc etc etc...
if we start with bash, what about zsh, fish, etc...
should probably install to /usr/share/bash-completion/completions/<something>, but I'm a bit lost as to where to add this bit.

I personally don't care much - definitely won't help with other shell completions but I'd be happy to (slowly) add up other commands and update once in a while; the most critical for me really is set/get_param completion and I've set that up in our configuration management system so this is mostly freebies / possibly call for help to finish.
