shift

Used to shift the positional arguments to left by N. if no arguments passed, then N is 1. if an argument is passed. it should be an integer. and in that case N is the first argument.

For example, calling shift with no arguments causes $1 to become $2, $2 to become $3, $3 to become $4 and so on. If an argument is passed. for example 3. The arguments are shifted by 3 steps. $1 becomes $4, $2 becomes $5, $3 becomes $6 and so on
