NEWBIE: posible sintax error

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, just trying to print the size of a ftp'd file.

 for $file (@files) {
      $ftp->get($file) and $ftp->delete($file);
      $remotesize = $ftp->size($file);
      $localssize=(stat ($file))[7];
      print "$file $localsize $remotesize $theGMTime"; #<-line 25
     }
[download]

but it throws " Use of uninitialized value in concatenation (.) or string at -e line 25" and the remotesize and localsize has no value

`$localssize=(stat ($file))[7]; # ^^ print "$file $localsize $remotesize $theGMTime"; #<-line 25 # ^` [download] Of course `use strict; use warnings;` [download] would have found that for you!	[reply] [d/l] [select]

That's exactly why strict and warnings are so important. Use them, and they'll find errors for you!	[reply]

The first thing that strikes me is that you `get` the file then `delete` it from the remote host and, only after it has been deleted, then try to `size` a file that no longer exists. Cheers, JohnGG	[reply] [d/l] [select]

More information would be useful. What module are you using for the ftp interface? Also the line `$ftp->get($file) and $ftp->delete($file);` struck me as odd. Again as I do not know what module you are using I can't say for sure but it seems like you wouldnt want to get and delete the file before you do anything. Also for future reference, please spend five seconds doing a simple proofreading of your post. When 50% of your title is misspelled and 25% is all capitalized many monks will answer other people's questions first.	[reply] [d/l]
