The rm (remove) command can delete files:

$ rm file1 file2 file3

or recursively delete directories:

$ rm -r dir1 dir2 dir3

Some Useful Options:

-f “Forces the deletion ignoring any errors or warnings.
-i “Asks before deleting each file”
-r recursively removes a dir(s) and it’s content(s). Use with extreme caution, especially if combining it with the -f option!

You can also use the rmdir command:

The rmdir (remove directory) command deletes one or more empty directories you name.

To delete an entire directory path (Use with extreme caution!) use the -p option along with the directory path (not just the directory name):
rmdir -p dir1/dir2/dir3

The above example would delete not just dir3, but dir1 & dir2 as well!

This will delete dir1,dir2 & dir3!
