If you are using unix, you can do the following (syntax assumes HP-UX):
# create named pipe
mkfifo expdat.dmp
# compress the output from the named pipe
cat expdat.dmp | compress > expdata.dmp.Z &
exp .....
# Wait for background process to complete compression of export file
wait
You can also use the same technique with either gzip or the zip/unzip shareware utilities, of course with different syntax for those commands. FYI - zip will provide much better compression than compress. I use it where I work for this purpose (as well as others).
Hope this helps,
