In addition to using exact filenames as arguments, we can use special characters like * to select groups of files. These special characters are called wildcards. For example, here we use cp to copy all files in the current working directory into another directory.

cp * my_directory/

Here, w*.txt selects all files in the working directory starting with “w” (prefix) and ending with “.txt” (suffix), and copies them to my_directory/.

cp w*.txt my_directory/

Let’s try out the wildcard symbol in this filesystem!

Note that you can access the layout of the filesystem here.



We’re back at the root movies/ directory! From here, navigate to the comedy/ directory.


In this directory, use the touch command create a new file named shrek.txt. After doing so, list the contents of the current directory.


Then, using a wildcard, copy all files in the current directory into the satire/ directory.


Without switching directories, look inside the satire/ directory, listing all its contents. You should see a copy of the files the_office.txt and shrek.txt in this directory.


Navigate to the action/ directory using this single command:

cd ../action/

Here we navigate up one directory, and then into the action/ directory.


Now let’s try using the wildcard * with a prefix and a suffix.

With a single command, copy all files in the current directory that start with m and end with .txt, to the scifi/ directory.


Without switching directories, list all the files and directories in scifi/.

You should see a copy of all text files starting with "m": matrix.txt, matrix-reloaded.txt, and matrix-revolutions.txt.
