Re^3: -s testing for empty file; works on local, but not on remote

in thread -s testing for empty file; works on local, but not on remote

There is one difference:

If you don't check for errors, errors (incl non-existent files) being returned by -s will be mistaken as empty file.

If you don't check for errors, errors (incl non-existent files) being returned by -z will be mistaken as non-empty file.

    What exactly do you mean by 'error'? if the -s/-z can't figure if the file has anything in it or not?

      stat can fail for a number of reasons.

      Add the following before the if (-s) line:

      use Data::Dumper; print(Dumper(-s "/home/vcg/Documents/Trial/temp")); print(Dumper("$!"));

      What's the output?
