Want to see what’s in a folder? Use ls to list all the files and directories.

$ ls
Documents Downloads Pictures

Add -l for more details, or -a to show hidden files.

cd – Change Directory

Need to move around? Use cd to change directories.

$ cd Documents

Want to go back to the previous directory? Use cd ...

mkdir – Make a Directory

Need to create a new folder? mkdir has got you covered.

$ mkdir MyNewFolder

Now you’ve got a brand-new folder to organize your files!

touch – Create a File

Want to create an empty file? Use touch.

$ touch myfile.txt

This creates a new file called myfile.txt.

cp – Copy Files or Directories

Need to make a copy of a file? Use cp.

$ cp myfile.txt myfile_copy.txt

You can also copy entire directories by adding the -r flag.

mv – Move or Rename Files

Want to move a file or rename it? Use mv.

$ mv myfile.txt Documents/

To rename a file, just “move” it to a new name:

$ mv oldname.txt newname.txt

To delete a directory and its contents, use rm -r. Be careful—this can’t be undone!

Hello, Linux!

It’s a simple way to peek at your files.

grep – Search Text

$ grep "Linux" myfile.txt
Hello, Linux!

This searches for the word “Linux” in myfile.txt.

chmod – Change File Permissions

Need to control who can read, write, or execute a file? Use chmod.

$ chmod 755 myfile.txt

This sets specific permissions for the file. (Don’t worry—you’ll learn what those numbers mean later!)
