    Got a problem piping command output to a perl script, in the test below
    the loop accepts the piped files but it also interferes with my STDIN!

    ===test=============================
    $ls -1 *.cfg | ./pp
    ls -1 *.cfg | ./pp
    file: hosts.cfg
    file: pseries.cfg

    type something : you typed :
    ===test=============================

    I do not get the chance to type something in after "type something"...

    Do i have to flush some variable inbetween the foreach loop and
    <STDIN>?
    Is looping trough <ARGV> or <> the best way to catch piped input?

    ===code=============================
    $cat ./pp
    #!/usr/bin/perl

    while ( <ARGV> ) {
      print "file: $_";
    };

    print "\ntype something : ";
    $answer = <STDIN>;
    print "you typed : $answer \n";
    ===code=============================

    thanks!
