Open a manual page

Opening a page

man followed by a command's name prints that command's manual. Every page follows the same layout, so once you can read one you can read them all:

• NAME: the command and a one-line summary of what it does.
• SYNOPSIS: how to invoke it. In cmd [OPTION]... [FILE]..., square brackets mean optional and ... means repeatable. This single line tells you the shape of the command.
• DESCRIPTION: the full prose, including every option.

On a normal terminal man opens the page in a pager you scroll with the arrow keys and quit with q (and search with /word). In this sandbox the page is printed straight to your output instead, but the content is identical.
