in thread df sometimes hangs in Win32 OS

So, what I think is being said is that the script this is in needs an OS checker so it can load a Win32 specific utility to do the job?

The script needs to be cross-platform. 95%+ of the installations are on *nix. Maybe 5% of the Win installs come up with this problem. So it's a pretty rare issue.

    I have a df utility on my windows system -- part of the UnxUtils package though it segfaults on my 64-bit OS -- but generally most windows systems will not have it, and expecting users to find and install one is naive.

    Far simpler I think to use something like:

    sub freespace { if( $^O eq 'MSWin32' ) { `fsutil volume diskfree .` =~ m[avail free bytes : (\d+)]; return ( $1 // die $! ) / 1024; } elsif( $^O eq ... ) { ... } else { `df -k .` =~ m[...]; return $1 // die $! } } ... my $free = freespace();

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

      Thank you - this is exactly what I need.
