[GE users] Qsub - o behavior

  Please forgive what I'm sure is a newbie question, but I am a 
newbie, and I've been unable to track down the answer to this via web 

  While no one including the developers appears to discuss this (and 
as far as I can tell it's not in the documentation), it appears that 
the 'qsub -o" command in SGE 6 appends to the output file rather than 
overwriting the output file if it exists. At least, that appears to 
be true for my setup (installed SGE binaries on TRU64 5.1A). So, is 
this true? And if so, is there any way to override this behavior? I 
have several scripts that rely on "qsub -o" being able to overwrite a 
file if that file already exists, and I would not enjoy changing them.

  All comments welcome and appreciated.
