The formula built, but is not symlinked into /usr/local
Could not symlink etc/bash_completion.d/docker
Target /usr/local/etc/bash_completion.d/docker
already exists. You may want to remove it:
rm '/usr/local/etc/bash_completion.d/docker'
To force the link and overwrite all conflicting files:
brew link --overwrite docker-completion
To list all files that would be deleted:
brew link --overwrite --dry-run docker-completion
Possible conflicting files are:
/usr/local/etc/bash_completion.d/docker -> /Applications/Docker.app/Contents/Resources/etc/docker.bash-completion
/usr/local/share/fish/vendor_completions.d/docker.fish -> /Applications/Docker.app/Contents/Resources/etc/docker.fish-completion
/usr/local/share/zsh/site-functions/_docker -> /Applications/Docker.app/Contents/Resources/etc/docker.zsh-completion
