1. Enable non-interactive use of brew sh, e.g.:

   brew sh './configure && make && make install'
   # or
   brew sh --cmd='gem install diamond'

2. Protect ENV["VERBOSE"] = "1" with if args.verbose?

Nice idea, good work so far!

@MikeMcQuaid good to merge?

Last question: wondering if anyone would want to do/add brew sh something.sh in future and, if so, that's what named should be doing and if -c should be doing what --cmd was before (--cmd could always come back as the long option in that case). Sorry that I only just thought of this now 😭

[MikeMcQuaid]

Made one final tweak. Thanks again @maxim-belkin!

manpages/brew.1 is broken here... Not sure what's causing this

[maxim-belkin]

[<script>] is causing this. 🤔

[maxim-belkin]

I can fix this by adding </script> after <script>

Thanks @maxim-belkin!
