10. Man & Help Pages
----
For nearly any command, we have help pages, or man pages to help us out if we want to know more about them.
Sometimes we even have them from within a program, or on a Readme file that came with the program if we are using one that we are unfamiliar with.
1. ls help = shows help page for the ls command.
2. man ls = will show a manual page for that command if it exists Press the Enter key to skip down line by line, press q to quit, if that doesn't work, we'll just press "Ctrl+c" to cancel a command as usual, but q should work for this.
