Hi tankergoblin,

try

unlink <*.txt> or die "Cannot unlink files $!";

or, more safely

if () {
    my $c = unlink  or die "Cannot do it $!";
    print "deleted ", $c, " files","\n";
} else {
    print "nothing to delete","\n";
}

#This will work, but will only die if it doesn't remove any
#If any files are removed (even if some could not be), you will not be notified
unlink </path/to/*.txt> or die "Cannot unlink files $!";
 
 
#### With this, you will be notified for each unsuccessful delete
foreach (</path/to/*.txt>) {
    unlink or warn "Could not remove $_:$!\n";
}

Check the script below, it will remove any .txt files from the given directory.
Do let me know, if you have any doubts.

Vikas.

#!/usr/bin/perl
 
$dirname = <STDIN>;
chomp($dirname);
opendir(DIR,$dirname);
while ( $file = readdir(DIR))
 {
  if ( $file =~ /\.txt$/)
  { 
    unlink $dirname."/".$file;
  }
} 
closedir(DIR);
