The <info>%command.name%</> command dumps the shell completion script required

<comment>Static installation
-------------------</>
Dump the script to a global completion file and restart your shell:
<info>%command.full_name% bash | sudo tee /etc/bash_completion.d/{$commandName}</>
Or dump the script to a local file and source it:
<info>%command.full_name% bash > completion.sh</>
<comment># source the file whenever you use the project</>
<info>source completion.sh</>
<comment># or add this line at the end of your "~/.bashrc" file:</>
<info>source /path/to/completion.sh</>
<comment>Dynamic installation
--------------------</>
Add this to the end of your shell configuration file (e.g. <info>"~/.bashrc"</>):
<info>eval "$({$fullCommand} completion bash)"</>
