To help us debug your issue please explain:

• Install wireguard-tools because I have to use wg to connect to an internal network

• What happened (include command output)
  When I start a new terminal, I see the following output:

-bash: complete: nosort: invalid option name
-bash: complete: nosort: invalid option name

I'm using brew's bash_completion, which I've installed into my .bashrc thusly (and I source my .bashrc in my .bash_profile):

# this is for git bash completion. I don't know if it's redundant to install it this way
# but I've always had it as a separate sourcing. It isn't the cause of the problem,
# but I wanted to include it just in case it mattered somehow
if [ -f $(brew --repository)/Library/Contributions/brew_bash_completion.sh ]; then
  . $(brew --repository)/Library/Contributions/brew_bash_completion.sh
fi

# I commented this out, and the `-bash: complete: nosort: invalid option name` disappeared
# Then, I enabled debugging with `set -x` (still enabled below), and pinpointed the causes
# of the error:
# ++++ complete -o nosort -F _wg_completion wg
# -bash: complete: nosort: invalid option name
# ++++ complete -o filenames -o nosort -F _wg_quick_completion wg-quick
# -bash: complete: nosort: invalid option name
if [ -f $(brew --prefix)/etc/bash_completion ]; then
  set -x
  . $(brew --prefix)/etc/bash_completion
  set +x
fi

• What you expected to happen
  I shouldn't see any errors when I start a new terminal

• Step-by-step reproduction instructions (by running brew install commands)
  On a Mac running macOS 10.12 Sierra, run the following:

brew install wireguard-tools

And then add brew bash completion to your .bashrc and .bash_profile:

if [ -f $(brew --prefix)/etc/bash_completion ]; then
  . $(brew --prefix)/etc/bash_completion
fi

Open a new terminal, and observe the following two errors on startup:

-bash: complete: nosort: invalid option name
-bash: complete: nosort: invalid option name

I don't see any reference to nosort in https://github.com/Homebrew/brew/blob/master/completions/bash/brew. What's your which bash output and bash --version output?

[hborders]

It's coming from whatever wireguard-tools adds. Maybe this is a wireguard-tools issue instead? I filed an issue on their mailing list, but it hasn't been approved yet.

[MikeMcQuaid]

Maybe this is a wireguard-tools issue instead?

Yes, sounds like it. Thanks!
