When man <cmd> or <cmd> --help or <cmd> -h doesn't show you how to use the command, what should you do to get the information you need?
For example, the command enable has no manual page.
- Type
enable --invalid_optionwill only show you the usageenable: usage: enable [-a] [-dnps] [-f filename] [name ...]without any explanation. - Since the term enable is too generic, searching online for ubuntu terminal command enable will only give you lots of unwanted results.
So is there a best way to get the manual of a command, when man <cmd> doesn't work?
enable's a builtin in zsh, so look at the zsh manual. – muru Nov 21 '18 at 05:41
