Sergey,
Thanks for the mkfifo idea. I've also come across "mknod myfifo p;compess < myinfo > myinfo.Z"
I'm looking at the two options, yet to ascertain whether second method works with gzip.
Do you know of any known troubles (Block/File corruption) with first method ? Do I have to "rm yourinfo" or I can re-use the piping file ( as in ascript) ?

Thanks once again,
Simon

Hello Simon,

You can make it like this:

mkfifo yourfifo
gzip <yourfifo >outfile.dmp.gz &
exp ... file=yourfifo
rm yourfifo
