Deleting a directory on Linux is very easy indeed. The rmdir command will perform this task adequately. You could also use the
rm -rf abc/ command to delete a directory, but rmdir is easier to remember.
eyjafjallajkull% rmdir abc
The rmdir command will not be able to delete a directory that is not empty, therefore you will need to use the
rm -rf command to delete it in that case.
eyjafjallajkull% rm -rf abc
Just be careful when using this command as you could accidentally delete a required directory. But this command is very useful when you are managing your Linux file-system.
