Use the below said script in your shell script it will export files greater 
than 2 gb.



echo "FULL EXPORT OF BLINK ON FOX HAS STARTED" |mailx 8774472907_at_skytel.com
. /export/home/oracle/aruns_data/oracle_env
ORACLE_SID=BLINK



export ORACLE_SID


cd $EXPORT_DIR


#

#  set maximum file size for each chunk of the export file

#



MAXFILESIZE=2000m


export MAXFILESIZE


#

# create filenames for the parts of the backup... for now let's go to 3

#


FILENAME1=$EXPORT_DIR/fullexport/backup1_$ORACLE_SID.dmp
FILENAME2=$EXPORT_DIR/fullexport/backup2_$ORACLE_SID.dmp
FILENAME3=$EXPORT_DIR/fullexport/backup3_$ORACLE_SID.dmp


LOGFILE=$LOGS/backup_$ORACLE_SID.log


#

#

#  create the pipes

#



mkfifo exportpipeaa


mkfifo exportpipeab


mkfifo exportpipeac


mkfifo wrkpipe


umask 000


#

# start the readers from the pipes to create the export files

#


dd if=exportpipeaa of=$FILENAME1 &
dd if=exportpipeab of=$FILENAME2 &
dd if=exportpipeac of=$FILENAME3 &




#

# start the reader from the wrkpipe to compress and split the export

#



dd if=wrkpipe|compress|split -b $MAXFILESIZE - exportpipe &


#

# start the export for real

#



exp "/" file=wrkpipe full=y compress=n buffer=4096000 LOG=$LOGFILE


#

# clean up after ourselves

#



rm exportpipeaa exportpipeab exportpipeac wrkpipe


#

#  if you haven't used all the pipes, the dd may still linger on

#    make sure to REALLY clean up

#



ps -ef|grep exportpipe|grep -vi grep|awk '{printf ("kill -9 %d; 
\n",$2)}'>kill.lst


chmod u+x kill.lst


sh kill.lst


rm kill.lst
