How do I use a wild card in this case?

The file always equals /home/inside/DVD*/bla_bla.txt. I'm looking for it to look at any DVD but it's not. bla_bla.txt is really in /home/inside/DVD3/bla_bla.txt

my $dir = "/home/inside/DVD*";
my $file = "bla_bla.txt";

  if (-f $dir/$file) {  
     move ("$dir/$file","${other_dvd}/.") || die "Can't copy $dir/$file $!\n";
  }

Is there more than one bla_bla.txt, and you're trying to move them all?

If you're not trying to move them all, which do you want to move?
is your move sub from File::Copy?
Ozo, you're a maniac. You never sleep! :D

Do You want use glob?

my $dir = "/home/inside/DVD*";
my $file = "bla_bla.txt";
my @MATCH = glob("$dir/$file");
foreach $m (@MATCH) {
  if (-f $m) {  
     move ("$m","${other_dvd}/.") || die "Can't copy $m $!\n";
  }
}

Assuming you want to check for a single file, then simply do

my $dir = "/home/inside/DVD*";
my $file = "bla_bla.txt";

if (-f <$dir/$file>) {  
     move ("$dir/$file",$other_dvd) or die "Can't copy $dir/$file to $other_dvd $!\n";
}

OK,
     I'm looping the content of a file.....

my $dir = "/home/inside/DVD*";

  open (FH, "$list") || die "can't open $list $! \n";
  while (<FH>) {
    chomp;
    @list = split / /;
    $files = $list[0];
   
  if (-f $dir/$file) {  
     move ("$dir/$file","${other_dvd}/.") || die "Can't copy $dir/$file $!\n";
  }

ozo,

Your last post is giving

Modification of a read-only value attempted at test.pl line 216, <FH> line 1.

move ($_,"${other_dvd}/.") || die "Can't copy $_ $!\n" if -f; is line 216

Any ideas?

Is there anything else near line 216?

I said for( <$dir/$file> ){  not if( <$dir/$file> ){

Author

Commented:
Right, I tried both and none of them worked

for ( <$dir/$file> ){

if( <$dir/$file> ){

and still getting

Modification of a read-only value attempted at test.pl line

That's very strange, because
move ($_,"${other_dvd}/.") || die "Can't copy $_ $!\n" if -f;
does not attempt to modify anything
What else is in the program?

Commented:
Ok I figured out one way to do this.

I'm not getting Modification of a read-only value attempted at test.pl line

my $dir = "/home/inside/DVD*";

  open (FH, "$list") || die "can't open $list $! \n";
  while (<FH>) {
  $file = (split)[0];

  $new_dir = qx(ls $dir/$file);
   chomp ($new_dir);
   
  if (-f $new_dir ) {  
     move ("$new_dir","${other_dvd}/.") || die "Can't copy $new_dir $!\n";
  }
