Not quite.

> If you deal with command-line tools often, it might take some time to figure out how to get help or check the version of a particular command (especially when shell completions are not available). In that case, you might try the most-known flags such as -h and -v but unfortunately not all the command-line tools follow these conventions (either due to conflicts with other flags or they just use another form). Instead of brute-forcing manually into getting help, you can run halp <command> and it will check the common arguments by running the command and checking the exit code.
