Now that we know how to use cp, mv, and ln, it's time to learn how to remove objects from the filesystem. Normally, this is done with the rm command. To remove files, simply specify them on the command line:

$ cd /tmp
$ touch file1 file2
$ ls -l file1 file2
-rw-r--r--    1 root     root            0 Jan  1 16:41 file1
-rw-r--r--    1 root     root            0 Jan  1 16:41 file2
$ rm file1 file2
$ ls -l file1 file2
ls: file1: No such file or directory
ls: file2: No such file or directory
