List of commands: Linux commands - Raspberry Pi Documentation

mkdir

You can use mkdir to create a new directory, e.g. mkdir newDir would create the directory newDir in the present working directory.

rmdir
To remove empty directories, use rmdir. So, for example, rmdir oldDir will remove the directory oldDir only if it is empty.
