Ubuntu Boot Camp 2013Using the Command Line -Tips & Tricks

Ubuntu Boot Camp 2013Basic Commands

1. Create a text file with gedit

2. Type in the following...this is my first command line exercise in Ubuntu

3. Save it to your desktop & name practice.txt

We will use this file to practice our commands today

ls: Lists the files in the current directory.

EG: ls

You can type ls -l to see all the file information including permissions and owner

EG: ls -l /var/cache/apt/archives

less: allows you to view/display a file contents

EG: less ~/Desktop/practice.txt

gedit: opens the text editor like notepad, so you may modify files.

EG: gedit ~/Desktop/practice.txt (now add another line of text then save)


pwd: shows the current working directory

cd: Allows user to change directories. When opening a terminal, a user will be in their

home directory. As a shortcut , substitute ~ in place of the home directory eg:

home/user1/Desktop is the same as ~/Desktop

mv: Moves a file to a different location or renames a file.

EG: mv ~/Desktop/practice.txt ~/Documents/practice.txt

EG: mv ~/Documents/practice.txt ~/Desktop/practice2.txt

cp: Makes a copy of a file

EG: cp ~/Desktop/practice2.txt ~/Documents

mkdir: Allows user to create directories (folders)

EG: mkdir ~/test


rm: Removes or deletes a file or an empty directory

EG: rm ~/Desktop/practice.txt (it does not work on directories that contain files)

If the directory contains files you must add -R ( recursively)

EG: rm -R ~/test

Ubuntu Boot Camp 2013Basic Commands – User Management

adduser: Creates a new user EG: sudo adduser user1

deluser: Removes a user from the system. To remove the user’s files and home directory,

add the -remove-home option

EG: sudo deluser -remove-home


addgroup: Creates a new group on the system EG: sudo addgroup teachers

delgroup: Removes a group from the system. Note: you cannot remove a group that is the

primary group of any users

EG: sudo delgroup


Alternatively, you may use the GUI or graphical interface to add users as well. Search Dash for Users...then unlock with your sudo password


passwd: Changes the user’s password. If run by a regular user, it will change his or her

password. If run using sudo, any user’s password can be changed.

EG: sudo passwd user1

Setting passwd for root account in Ubuntu:

As discussed, the root account is not activated by default in Ubuntu, in both the desktop

and server versions. Make it secure and not the same as sudo!!! ( !nt4u2c~ )

EG sudo passwd root

Now you will be able to enter and use recovery mode if needed, selecting either the net

root option (if you have internet connection) or root
