I want to read in a stream of characters from STDIN, ten process the information, then ask the user questions and read their answer.

Problem is, I can't figure out what I need to do to seperate the two stages.

Code: 

#!/usr/bin/perl
#
# A program that accepts input from the cmputil command and will diff 
+the files
# in question, prompting the user for a decision, and build an action 
+file
#



use File::Basename;

$| = 1;

open IN, "<$ARGV[0]";

open OUT, ">differences";

while (<IN>) {
        chop $_;
        ($file,$problem,@machines) = split(/,/, $_);

        ($name,$path,$suffix) = fileparse($file,"");
        print "$name -- $path -- $suffix\n";

        if($problem eq "different") {
                # get the file from the remote machine
                foreach $machine (@machines) {
                        next if ($machine eq "");
                        $tempfile = "/tmp/" . $name . "_" . $machine;

                        `rcp $machine:$file $tempfile`;
                        
                        print "comparing $name from $machine\n";
                        system "diff $file $tempfile";
                        print "(k)eep or (i)gnore this difference?\n";
                        $resp = <>;
                        print ">>$resp<<\n";
                        if($resp eq "k") {
                                print OUT "$machine $file\n";
                        }
                }
        }
}

The problem I have is the line $resp = <>; returns immediately without waiting for the user to input anything.

Do I need to flush STDIN or something?
