Final answer:

To create four subdirectories within a directory using brace expansion in Linux.


Explanation:

To create the four subdirectories named freemem, diskuse, openlist, and freedisk within the ~/backups directory using brace expansion, you can use the command:

mkdir -p ~/backups/{freemem,diskuse,openlist,freedisk}

This command will create the specified subdirectories in the backups directory. The -p flag ensures that parents of the subdirectories are also created if they do not exist.
