Hi Perl Monks, I'm trying to list the contents of a directory (/opt/tmp). I have tried the following options:

Option 1

my @files = grep(-f, <*.*>); foreach my $file (@files) { print "file = $file\n"; }

This code only list the files in my current directory /opt/, but i need to list the files in directory /opt/tmp/

Option 2

my @files = glob("/opt/tmp/*.*"); foreach my $file (@files) { print "file = $file\n"; }

This code doesn't print anything. I'm not even sure the glob works.

Option 3

my @files; opendir(DIR, "/opt/tmp/" or die "Cannot open dir"); @files = grep {-T "/opt/tmp/$_"} readdir DIR; foreach my $file (@files) { print "file = $file\n"; } closedir(DIR);

When i execute this code i always get an error: "Cannot open dir". However, the directory exists and has files in it.

I also tried some other options related to opendir, but the output was empty.

Can someone help me?

Thanks
