The Shell
utility is a command language interpreter, which reads commands from either a command string, a specified file, or the standard input. The command language shall be described in Shell
(5), The Shell Command Language.
Any extra arguments passed into arguments
are placed in the local variable $ARGV
and can also be accessed through the special variable $*
.
NOTE:
The Shell
utility does not promise POSIX sh
interoperability.
