You can use the following commands:
[a] rmdir command : remove empty directories.
[b] rm command : remove files or directories.
Linux Delete a Directory Command Examples
The syntax is as follows:
rmdir dirName
Login using the ssh client or open a command-line terminal
(select Applications > Accessories > Terminal under Gnome
desktop), than type the following command to delete empty directory
called foo:
rmdir foo
By default, the rm command does not remove directories. Use
the --recursive (-r or -R) option to remove each listed directory, too,
along with all of its contents including all files and subdirectories:
rm -r documents
You can also specifiy the full path:rm -r /data/dir1 rm -r /home/vivek/dir2 rmdir $HOME/mp3
