In computing, alias is a command in various command-line interpreters (), which enables a replacement of a word by another string. [1] It is mainly used for abbreviating a system command, or for adding default arguments to a regularly used command.

Tcsh is the only shell that provides this feature (in lieu of functions). \!# - argument selector for all arguments, including the alias/command itself; arguments need not be supplied.

Often one of the two files is either a hard link or a symbolic link to the other, so that either name refers to the same improved version of the C shell. The original csh source code and binary are part of NetBSD. On Debian and some derivatives (including Ubuntu), there are two different packages: csh and tcsh.
getopts is a built-in Unix shell command for parsing command-line arguments. It is designed to process command line arguments that follow the POSIX Utility Syntax Guidelines, based on the C interface of getopt. The predecessor to getopts was the external program getopt by Unix System Laboratories.
getopt is a system dependent function, and its behavior depends on the implementation in the C library. Some custom implementations like gnulib are available, however. [6]The conventional (POSIX and BSD) handling is that the options end when the first non-option argument is encountered, and that getopt would return -1 to signal that.
