Ask for input from the keyboard, if it is matched to a file in a particular directory, exit. If is does not match, looping for the input from the keyboard until it is matched.
Thanks in advance!

rj2 is quicker than i am.  but here is my version.  i posted it because it allows the script to continue instead of just exiting.  give rj2 points, not me.


my $dirname = "/home/jon/bin";

opendir DIR,"$dirname" or die "$!";
my @files = grep /.*/, readdir DIR;

my $last = 0;
while($last != 1){
    print "filename? ";
    $_ = <STDIN>;
    foreach my $filetest (@files){
        if($filetest eq $_){ $last = 1; last; }

print("matched $_\n");
