what we did. (Think lots of subprocess.Popen + subprocess.communicate and shredding the output of mm commands. And yes, we wrote a parser which could shred the output of either –Y or tabular format.)

I'm pretty certain Yuri told me that mmlspool was completely unsupported and didn't have -Y a couple of years ago when we did the original GPFS UG RFEs prior to 4.x. I figure that earns cookies.<br>

Perhaps in light of the mmbackup thread; "Will fix RFEs for cookies?". Name your price ;-)<br>

I must say I've not seen any headers increment above 0:1 since ... er .. 3.3(?), so they're pretty static.<br>

Now, if only mmlspool supported -Y ... or if _all_ commands supported -Y, I might even FedEX beer.<br>
