I'm having a problem with the results of the Unix 'du' command in that I get different results when I execute the 'du' command from the Unix command line... du -sb <directory-path> and when I execute the 'du' command from a Perl script using backtic statement. my($size) = `du -sb <directory-path>`; However the differing results only occurs on some directories and not on others. So far I haven't seen a difference on files, just directories. Can anyone shed some light on this for me. Also, I get the daily digest so, I'd appreciate a direct reply. Thanks in advance Tony F.
