This question already has an answer here:
man and in a single command from
--help, I'd like to know further information for certain options. I know that for every command, by default the option
--help will print a help page with a list of available options. But how can I get only the description of a particular option?
In the web and here in particular we see a lot of instructions and commands and I'd like to read more about it without searching in the full list.
For example, I know that
rsync -h means
-h, --human-readable output numbers in a human-readable format
ls -l means
-l use a long listing format
How to get that specific information in a short command?
