Hello rdrtx1,

I think in shell unlike awkthere is no need for function function_name, you could put directly as function_name {....}, so it could be written as follows.
Code:
#!/bin/ksh
process_files ()
{
   echo There are ${#} parameters..
   for i in $*
   do
      if [ ! -f "$i" ]
      then
         echo "Error $i does not exist!"
      else
         echo "Error $i does exist, please proceed".
      fi
   done
}

Thanks,
R. Singh
