You are, and beauty is in the eye of the beholder, your code may look
better to you, but to the computer it definitely doesn't. Perfect
example, given,
open(test123, ">>/home/staff/wot/public_html/perl/test.csv") or die
("File test.csv could not be opened for writing");
What do you think the following three lines do?
flock(test, 2);
seek(test, 0, 2);
close(test);
Or how about your error conditions,
or die "Error adding $file_gif: $!\n";
or die "Error adding $file_zip: $!\n";
So much for including the filename.
'strict' and 'warnings' will save you hours of headache.
