Silent Clusterware Installation Question

Question

Hello -
I am attempting to run a silent installation of Clusterware. I am installing on Linux, and here is part of my script:
/oracle_software/11g_clusterware/clusterware/runInstaller -silent -responseFile \
$ORA_SCRIPTS/RAC_installation_pckg/crs.rsp
However, I want the above process to finish in the script before going to the part of my script that runs the root commands for the installation. Currrently, the call to the command itself completes, and then the script goes to the part to run the root commands, while the above installation is still running. How can I get it to only call the root commands after the Clusterware installation has completed? Can I make use of wait command in my Linux script?
Any help or insight is greatyly appreciated!
Thanks,
Mike

1. make SSH user equivalance for root user on RAC1 and RAC2 hosts
2.
login as root
root@RAC1 #./run.sh

./search.sh &
####END############

/oracle_software/11g_clusterware/clusterware/runInstaller -silent -responseFile $ORA_SCRIPTS/RAC_installation_pckg/crs.rsp >>/tmp/out
###END ###################
######### search.sh #########
#!/bin/bash
for ((a=1 ; a <= 1000 ; a++ ))
do
egrep '/u01/crs/oracle/product/10.2.0/cr/root.sh' /tmp/out>dev/null
if [ $? -eq 0 ]
then
/u01/app/oracle/oraInventory/orainstRoot.sh
ssh RAC2
/u01/app/oracle/oraInventory/orainstRoot.sh
exit
/u01/crs/oracle/product/10.2.0/cr/root.sh
ssh RAC2
