As you can see, the Bash Argsparse Completion module can automatically
29
enable the bash completion for the scripts you develop with the Bash
30
Argsparse library.
31

32
To enable completion for your own scripts, please ensure
33
bash_completion is enabled, and then in your ~/.bashrc, add lines such
34
as:
35

36
    . argsparse-completion.sh
37
    complete -F _argsparse_complete yourscript your_other_script
