1. command-line interpreter command interpreter command line option Or "option", "flag", "switch", "option switch" An argument to a command that modifies its function rather than providing data. Options generally start with "-" in Unix or "/" in MS-DOS. This is usually followed by a single letter or occasionally a digit. Some commands require each option to be a separate argument, introduced by a new "-" or "/", others allow multiple option letters to be concatenated into a single argument with a single "-" or "/", e. g. "ls -al". A few Unix commands e. g. ar, tar allow the "-" to be omitted. Some options may or must be followed by a value, e. g. "cc prog. c -o prog", sometimes with and sometimes without an intervening space. getopt and getopts are commands for parsing command line options. There is also a C library routine called getopt for the same purpose.
