12 commands every Linux newbie should learn

Still scared of the command line? Don’t be. These commands are a quicker and easier way to get things done in Linux.

It's a testament to how far Linux has come that users today don't typically have to use the command line if they don't want to. Such is the quality of the graphical user interfaces in many modern Linux distributions that there's simply no need, in general.

Yet the command line can be a highly efficient way of getting things done in the Linux world--it's often a much simpler, easier and more direct method than clicking through all the menu choices, in fact.

I believe fear of the command line is one of the top mistakes newcomers to Linux sometimes make. For that reason, let's look at some of the main commands any Linux user should know.

1. man

I begin with the "man" command because in many ways it's the most fundamental. This command is what you should use when you want to learn more about another command.

Essentially, "man" displays online manual pages to provide a basic introduction to the various other commands that are available. Using it can help you understand the functions of those commands as well as how to use them. You can even type "man man" to get the man page for "man" itself.

If you're ever unsure of a command you're about to use, try typing "man" along with the command to learn more about exactly what it does.

2. ls

Another fundamental command is "ls," which displays the contents of your current directory. For example, "ls ~" will show you the files in your home directory.

3. pwd

To find out which directory you're working in, type "pwd," which is short for "print working directory." Typed in the desktop directory, for example, this command will return "~/desktop."

4. cd

To change the directory you're in, use this command. To switch to the desktop directory, for instance, you'd type "cd desktop."

5. mkdir

To create a new directory, this is the command you'd use. For example, "mkdir pictures" will create a directory called "pictures."

6. find and locate

To search for a file, you can use either "find" or "locate," both of which are very similar.

7. cp

This is the command to use when you want to create a copy of a file with a new name. Type "cp cats dogs," for instance, and you'll get an exact copy of "cats" named "dogs"; the file "cats" will still be there too.

8. mv
