Life Cycle
Shell scripts often serve as an initial stage in software development, and are often subject to conversion later to a different underlying implementation, most commonly being converted to Perl, Python, or C. The interpreter directive allows the implementation detail to be fully hidden inside the script, rather than being exposed as a filename extension, and provides for seamless reimplementation in different languages with no impact on end users.

Famous quotes containing the words life and/or cycle:
“A woman can get marries and her life does change. And a man can get married and his life changes. But nothing changes life as dramatically as having a child. . . . In this country, it is a particular experience, a rite of passage, if you will, that is unsupported for the most part, and rather ignored. Somebody will send you a couple of presents for the baby, but people do not acknowledge the massive experience to the parents involved.”
—Dana Raphael (20th century)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
