DELTREE (Delete Tree) on Linux

In Linux, there is a handy command to delete a directory with all files and sub-directories in it:

rm -Rf directoryname

Sometimes, some home built Linux needs the super user privilege. So, add the sudo command as the prefix.

sudo rm -Rf directoryname

The details of Linux rm -Rf directoryname command:

• rm: remove files or directories
• -R (recursive):  remove directories and their contents recursively
• -f (force): ignore nonexistent files and arguments, never prompt
• directoryname: the specific directory to be deleted

This is a very powerful command. So, use it with care.
