When opening a shell, your will be logged in with your active account to your home directory (this is usually in /home/user_name).

Note that every command has lots of options available. To see all the manual pages for the specific command, simply type "man ". It is important to understand that under Linux operating systems, commands are case-sensitive. This means that "A" is different from "a".

To go through the file system, use:

- pwd - Prints out on the screen the working directory (eg /etc/ssh)
- cd - changes directory (eg cd .. - goes up one dir; cd etc - enters /etc dir)
- ls - lists the content of the directory
- mkdir - creates a new directory (mkdir dir_name)
- touch - creates a new file (touch file_name)
- rmdir - removes a directory (rmdir dir_name)
- cp - copies a file/directory (cp source_file destination_file)
- mv - moves a file/directory - also used for renaming a file or directory (mv old_location new_location or mv old_name new_name)
- rm - removes files (rm file_name)    More detail...
