# bash completion file for docker-machine commands
#
# This script provides completion of:
#  - commands and their options
#  - machine names
#  - filepaths
#
# To enable the completions either:
#  - place this file in /etc/bash_completion.d
#  or
#  - copy this file to e.g. ~/.docker-machine-completion.sh and add the line
#    below to your .bashrc after bash completion features are loaded
#    . ~/.docker-machine-completion.sh
