Yesterday on my answer:
'You can always use `-h` / `--help`'
they gave me reply:
'There isn't command `-h` on my Limux'
My first reaction was a facepalm, but then I thought: How was he supposed to
know that?
Very new users don't fully understand command line concepts. They don't know
how to start. How to get help. They don't know things that are "obvious" to
people working in the console.
----
Therefore, after calling -h/--help, I suggest displaying a message like:
You have just used the `-h` argument, which is used to get help on a specific
command. Arguments are given after the program name and are used to modify the
program's operation. E.g.: usage:
somecommand --help
This will display a summary of the command usage (list of available options).
If you need more information about the command you can use:
man somecommand
To display text only on one screen, process the command result with another
more/less command, e.g.:
somecommand --help | more
You can also search for a word in the displayed result:
somecommand --help | grep word
BTW: Pressing [Esc] or [Q] in many cases allows you to return to the shell.
REMEMBER: Sometimes you need to put a colon between them to avoid turning into
a random character generator.
