Shift positional parameters

shift

Commands to  the shell  sh can  be stored in  a file,  or script.
Positional parameters pass  command line information to a script,
as described in the article on sh.

shift  changes  the values  of  positional  parameters.  The  old
parameter values $22, $33, ...  become the new parameter values $11,
$22 ....  shift also reduces the value of $#, which gives the num-
ber of positional parameters, by one.

The shell executes shift directly.
