# `--help`
|
|
|
|
Usage help. Provide help for the subject given as an optional argument.
|
|
|
|
If no argument is provided, curl displays the most important command line
|
|
arguments.
|
|
|
|
The argument can either be a **category** or a **command line option**. When a
|
|
category is provided, curl shows all command line options within the given
|
|
category. Specify category `all` to list all available options.
|
|
|
|
If `category` is specified, curl displays all available help categories.
|
|
|
|
If the provided subject is instead an existing command line option, specified
|
|
either in its short form with a single dash and a single letter, or in the
|
|
long form with two dashes and a longer name, curl displays a help text for
|
|
that option in the terminal.
|
|
|
|
The help output is extensive for some options.
|
|
|
|
If the provided command line option is not known, curl says so.
