Hi

from 'man bash':

Code:

       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.

so the effect is basically to switch to the (n+1)th command parameter.

Anyway, what are you actually trying to accomplish?
