[SGVLUG] awk question

[Ramsin Savra]

  Hi Tom,
   
  Do you mean that if I shift the parameter then it would work?
   
  Thanks,
  R

Shift

$man shift
[bash builtins...]
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 parame-ters 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.
