No, they are not! You simply don't have variable interpolation within
the single quotes, so your '$pipe' stays literally what it is.

While we are at it, when printing error messages from failed system calls
(e.g: unlink), you may want to put $! in the message string so you'll get
meaningfull message (e.g: "Permission denied", "No such file or directory").
If you 'use English;' than the previous variable may be named $ERRNO.
