Shell completions do not look for the new launchd plist names

brew doctor output

Your system is ready to brew.

Verification

• I ran brew update twice and am still able to reproduce my issue.
• I have supplied my brew doctor output above and it seems unrelated to my issue.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.
• I did not use AI/LLM to create this issue, or I disclosed the tool and model used; I will answer maintainer questions myself without AI/LLM.

What were you trying to do (and why)?

I was trying to tab complete services when doing brew services <start/stop/restart>, which worked previously when the launchd plist files were using the old name.

Now they're using the new sh.brew.<name>.plist, the completion scripts don't find them.

Bash: https://github.com/Homebrew/brew/blob/main/completions/bash/brew#L120
Fish: https://github.com/Homebrew/brew/blob/main/completions/fish/brew.fish#L220
ZSH: https://github.com/Homebrew/brew/blob/main/completions/zsh/_brew#L340

I assume it's just a case of having to add the sh.brew. case.

What happened (include all command output)?

When tab completing the service, it only completed services with the old plist file names.

What did you expect to happen?

Should complete any service for any Homebrew service plist.

Step-by-step reproduction instructions (running brew commands)

Install any formula that has a service, then attempt to tab complete it.

brew install postgresql@18
brew services start <press tab>
