## Bash completion
To activate, you need to source `bash_completion`:
[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
Put the above sourcing line just below the sourcing line for NVM in your profile (`.bashrc`, `.bash_profile`).
### Usage
nvm
$ nvm [tab][tab]
alias copy-packages help list run uninstall version
clear-cache deactivate install ls unalias use
nvm alias
$ nvm alias [tab][tab]
default
$ nvm alias my_alias [tab][tab]
v0.4.11 v0.4.12 v0.6.14
nvm use
$ nvm use [tab][tab]
my_alias default v0.4.11 v0.4.12 v0.6.14
nvm uninstall
$ nvm uninstall [tab][tab]
my_alias default v0.4.11 v0.4.12 v0.6.14
