in thread file listing within skript not working

Thanks a lot for Your help! I'll ask our server-admins about selinux. I am pretty sure you are right. When I changed the script to

my @files = glob "$datenDir/*.xml";
it does not even write anything into the logfile. So I think the listings within scripts might be forbidden.

And thanks for directing me to "glob". Don't know why I didn't use it - I think I need something to drink :-)

    Well said moritz ++

    McSvenster Perl has many ways to do things,you can also use readdir() function this way,

    use strict; use warnings; use Data::Dumper; opendir (DIR, "/home/vinoth/"); my @files = grep /\.xml$/, readdir DIR; print Dumper \@files;

    I am not telling this is the best way, but its also one of the way.

      It's getting more and more confusing for me...

      But maybe I found the critical point: When I use the backticks perl writes to the logfile until the program comes to the line with the backticks. But when I use "glob" instead, perl executes the whole program before it performs any file-writing.

      Is this right? And more important: Can you explain it to me? (you see, I am a beginner...)
