Dump the script to a global completion file and restart your shell:

<info>%command.full_name% bash | sudo tee /etc/bash_completion.d/{$commandName}</>

Or dump the script to a local file and source it:

|
|
<info>%command.full_name% bash > completion.sh</>

|
<comment># source the file whenever you use the project</>
|
|
<info>source completion.sh</>

<comment># or add this line at the end of your "~/.bashrc" file:</>

|
<info>source /path/to/completion.sh</>

<comment>Dynamic installation
