I am writing a perl script to do some file comparisons, but I would like it to take inputs similar to how korn does it....i.e.    script.sh input1 input2....
like a=$1   b=$2......

What is the easiest way to do this...

Here you go.  Pretty self explanatory I think, but let me know if you need more info.


#!/usr/bin/perl

print "You passed " . scalar(@ARGV) . " arguments\n";
print "The argument values are:\n\n";

foreach $arg (@ARGV) {
   print "$arg\n";
}

probably not self explanatory (for everyone), but more perlish ;-)

#! /usr/bin/perl
$\="\n";
print "You passed ",$#ARGV+1," arguments";
grep(print,@ARGV);

I would call that less perlish
More perlish might be:

#!/usr/bin/perl
$\="\n";
print "You passed ".@ARGV." arguments";
print "The argument values are:\n";
print for( @ARGV );

I figured it out about 1 hour after I posted.
I used......

open F,"<$ARGV[0]" or die "Can't open $ARGV[0] because $!";
$count{$_} |= 1 while <F> ;
open F,"<$ARGV[1]" or die "Can't open $ARGV[1] because $!";
$count{$_} |= 2 while <F> ;

Since BlackDiamond answered first I will give him the credit......Thanks for the help guys...
