# Command-line Completion
Docker Machine comes with [command completion](http://en.wikipedia.org/wiki/Command-line_completion)
for the bash shell.
## Installing Command Completion
### Bash
Make sure bash completion is installed. If you use a current Linux in a non-minimal installation, bash completion should be available.
On a Mac, install with `brew install bash-completion`
Place the completion scripts in `/etc/bash_completion.d/` (`` `brew --prefix`/etc/bash_completion.d/`` on a Mac), using e.g.
files=(docker-machine docker-machine-wrapper docker-machine-prompt)
for f in "${files[@]}"; do
curl -L https://raw.githubusercontent.com/docker/machine/v$(docker-machine --version | tr -ds ',' ' ' | awk 'NR==1{print $(3)}')/contrib/completion/bash/$f.bash > `brew --prefix`/etc/bash_completion.d/$f
done
Completion will be available upon next login.
