arsdb in batch, how can I control where it writes the exported file?

export DSNAOINI=/path/to/cli.ini;                     
export STEPLIB=DB2.V11R1M0.SDSNLOD2:DB2.V11R1M0.SDSNLOAD; 
cd /directory/to/write/to;                                     
/usr/lpp/ars/V9R0M0/bin/arsdb -I ARCH900 -vx ARSHOLD;     
/usr/lpp/ars/V9R0M0/bin/arsdb -I ARCH900 -vx ARSHOLDMAP;

The output will be written to /directory/to/write/to
