in reply to Reading command output buffer

Are you certain there's at least 4096 bytes in the SQL dump? The read would return an undef if that's not the case. Then the while block wouldn't get executed.

Revised: As per Fletch I had it wrong.

I'd still test the error return, though...

    Erm, no. read will try to read up to 4096 and will return the number actually read (0 on eof, or undef if there's an error like trying to read when there's no data on a non-blocking handle).
