GOOGLE !!!

Google is your best friend. Unless you're looking up the details of a specific command or file format, Google should be the first resource you consult for any question. Make it a habit!!!

man command

The manual pages, usually called "man pages" because they are read with the man command. Man pages are typically installed with the system.

man: read man pages

man title formats a specific manual page and sends it to your terminal.

• For example we use the man command for ls command

$ man ls

As a result you get a page with:

• Name of the command
• Synopsis of the command
• Description of the command

And some other options that we will discuss later.
