Try this script on for size, it's working for me, anyway...
#!/bin/csh -f
#
# check for program and start it if it is not found
#
echo "Check/starting process"
#
# program name should be $1
#
if ($1 == "") then
echo "usage: $0 program-to-check"
exit
endif
set STR = $1
echo " -- starting "$STR
#
# see if it is running and start it if needed
#
if (`ps -aux|grep -v grep|grep -c $STR` == 0) then
echo " -- starting process"
$STR >>& /dev/null &
else
echo " -- process already running"
endif
#
# done
