Brew commands autocomplete doesn't work about brew

[MikeMcQuaid]

@dbzix glad you got it resolved.

[MikeMcQuaid]

Did you read/follow https://docs.brew.sh/Shell-Completion?

[dbzix]

@MikeMcQuaid Yes, and it didn't help.
I've also tried to install bash-completion, but received:

$ brew install bash-completion

Error: Cannot install bash-completion because conflicting formulae are installed.
  util-linux: because both install `mount`, `rfkill`, and `rtcwake` completions

Please `brew unlink util-linux` before continuing.

Unlinking removes a formula's symlinks from /home/linuxbrew/.linuxbrew. You can
link the formula again after the install finishes. You can `--force` this
install, but the build may fail or cause obscure side effects in the
resulting software.

Installing bash-completion@2 didn't help, too.

UPD.: Also, the page you provided says:

Homebrew comes with completion definitions for the brew command.

I suppose it assumes that for brew command completions there is nothing that should be done additionally. Am I wrong here?

[MikeMcQuaid]

@MikeMcQuaid Yes, and it didn't help.

What steps did you follow, what did they output, what else have you tried, what shell are you using, etc.

Hey, @MikeMcQuaid!
I finally resolved the issue by running brew completions link and then adding the piece of script mentioned here to my .bashrc file.

The problem was obviously in blindly following the suggestion to add this script to either .bash_profile or .profile.
So, anyway, thanks for trying to help.

But I would like to make a little proposal here.
It would be nice and simple for users to have something like eval "$(brew init bash)" just as some other tools do. And you just put it right in your config file specific to the shell you use.
