Here is the video version, if you prefer it:
If you don’t want to read through man pages of a command to find out how it is used, you can specify the --help flag (its equivalent short option is -h) when executing a command, which will give you a description of how the command is used in a very concise and clear way.
Not all (executable) commands support the --help flag, but I found myself using --help more often than man.
Thank you for reading and hope you learned something useful!
