Shift positional parameters.

Syntax shift [n]

The positional parameters from *n*+1 ... are renamed to $1 ....

Parameters represented by the numbers $# down to $#-n+1 are unset.

*n* must be a non-negative number less than or equal to $#. If *n* is 0, no parameters are changed. If *n* is not given, it is assumed to be 1. If *n* is greater than $#, the positional parameters are not changed.

The return status is greater than zero if *n* is greater than $# or less than zero; otherwise 0.

shift is a bash builtin command.
