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:
“It is a conquest when we can lift ourselves above the annoyances of circumstances over which we have no control; but it is a greater victory when we can make those circumstances our helpers,—when we can appreciate the good there is in them. It has often seemed to me as if Life stood beside me, looking me in the face, and saying, “Child, you must learn to like me in the form in which you see me, before I can offer myself to you in any other aspect.””
—Lucy Larcom (1824–1893)
“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)
