The “man” command can be used on Linux to display the manual of an inputted command. To use this command type “man” followed by a space and then a Linux command. Example:

man cd

This will display the manual for the Linux command “cd”. This is very useful for starting off understanding Linux commands. And when in more doubt Google or asking questions to your professor is the answer.

The “cd” command is useful for going into directories or folders. Example:

cd

After using “cd” you add the option if which directory/folder you want to go into. Such as “cd familyphotos”, you can even get to directories not close to the one you're in like “cd ~/games/somegame/unrelated”.

The “mkdir” command is useful for creating folders. Example:

mkdir

After using “mkdir” you add the name of the folder. For example “mkdir folder” will create a folder named “folder” in whatever directory you are in. You can also use full paths like “mkdir ~/classes/unix” to create a folder that may not be in the same directory as you.
