I have been working on my scripts for user/group permissions today. This idea has been on my back burner for awhile. I’m sure others have done this before. I just haven’t encountered them yet.

I was thinking of just trying to find the flags where they start a line and put everything in a string array until the next line that starts with a flag. Then I would just call the script with the command, a loop would match the flags and print the matches.

    Inspired by explainshell, I wrote a script (https://github.com/learnbyexample/command_help) to be used from the terminal itself. It is a bit buggy, but works well most of the time. For example:

    $ ch grep -Ao
           grep - print lines that match patterns
    
           -A NUM, --after-context=NUM
                  Print NUM lines of trailing context after matching lines.  Places a
                  line containing a group separator (--) between contiguous groups of
                  matches.  With the -o or --only-matching option, this has no effect
                  and a warning is given.
    
           -o, --only-matching
                  Print  only  the matched (non-empty) parts of a matching line, with
                  each such part on a separate output line.
