in reply to Error in script

Use -s test:

#!/bin/perl # To remove all 0 byte file in a folder my $dir = "/home/bob/mytemp"; while (<$dir/*>) {unlink $_ unless (-s)}

Update: first line fixed. When testing I had #!/home/edi/perl but I know our installation is unusual, so I just copied the line from the OP to match his environment .. I thought it looked strange!

I leave the parentheses around conditions deliberately. It helps the less perl-literate of my co-workers.

My solution will only delete files in $dir; in the OP it mentions directory and below. find .. -exec rm is the tool to use in that case.

    Though fix your first line. #! makes us all happy. :)

    (And I don't bother with parens around the -s, but both work fine...)
