Dynamic bash aliases (loosely based on rbenv).
The simplest method is a git checkout:
$ git checkout https://github.com/t3hpr1m3/dalias.git ~/.dalias
$ echo 'export PATH="$HOME/.dalias/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval $(dalias init)' >> ~/.bash_profileYou will need to restart your shell for the above to take effect.
Usage is fairly straightforward. Navigate to a directory where you wish to add an alias. Let's say that in this directory, you want to run rspec within your Docker container (via docker-compose):
$ dalias add rspec docker-compose run app bundle exec rspecdalias is released under the MIT License.
