Read a book or online tutorial about Unix basics.

"touch" creates a file or updates the file's modification time if it
already exists.

One of the basic tenets of Unix philosophy (that I wish people would
apply to voicemail systems) is that if a command succeeded, it doesn't
tell you anything in the interaction channel.  If it fails, then you see
the complaints.
