Compressed Export file

Dear sir,
I'm running with Oracle 8.1.6 on RH Linux 6.2EE. My daily export dump files are very huge and my disk space fallen alarmingly low. I want to do a compressed export using gzip and split, as Linux 6.2 has a limitation in size of 2G per file. If Any one out here had already implemented the same, can you please post the script, here . Actually I wrote a small script but it is throwing errors:
ERROR:
split: /u09/mytools/expimp/expdmp.gz_: No such file or directory
LRM-00118: syntax error at '=' at the end of input
EXP-00019: failed to process parameters, type 'EXP HELP=Y' for help
EXP-00000: Export terminated unsuccessfully

Here is my Script:
====================
# -- export_dl.sh:
ORACLE_HOME=/opt/oracle/product/8.1.6
ORACLE_SID=cmsrpt1
OUTPUT_FILE=/u09/mytools/expimp/expdmp.gz_
export ORACLE_HOME ORACLE_SID OUTPUT_FILE
#
# Creation of a pipe for output of export
rm -f /u09/mytools/expimp/p
mkfifo -m 777 /u09/mytools/expimp/p
# Start export
#
cat p|gzip |split -b 1000m ${OUTPUT_FILE} &

#created an external user OPS$ORACLE inorder to protect
#user ids and passwords.

/opt/oracle/product/8.1.6/bin/exp / FILE=$p \
PARFILE=/u09/mytools/expimp/testexportparam_dl

# End export
exit

--testexportparam_dl:

# -- exportparam_dl :
LOG=/u09/mytools/logs/testexport_dl.log
CONSISTENT=Y
COMPRESS=N
#OWNER=dloader
TABLES=(d_claim,d_fintx)

It would be a great help for me if any one can correct this script or send me their script which is implemented successfully. Because i need to productionalise this script by today evening.

Many Thanks in advance

Export through a named pipe.

Just keep in mind you'll need to import via the pipe as well.

Thanks for your kind help Ken. I'll go thru that site and try to implement it.
