we do something similar in our startup script (though I cannot claim credit
for this bash bashing). note success() and failure() are redhat-isms
# manual callout for cfagent; let it only run for upto 2min
echo -n "cfagent execute: "
/usr/sbin/cfagent -q > /dev/null 2>&1 &
RETVAL=$?; subpid=$!
if [ $RETVAL -eq 0 ]; then
maxtime=120
while kill -n 0 $subpid 2> /dev/null; do
if [ "$maxtime" -lt 1 ]; then
kill -n 9 $subpid 2> /dev/null
failure "cfagent boot timeout"
RETVAL=1
break
fi
sleep 1
maxtime=$((maxtime-1))
done
kill -n 0 $subpid 2> /dev/null || [ "$maxtime" -gt 0 ] && \
success "cfagent boottime execute"
The assumption is that a reasonable cfengine run will never take two minutes
to complete.
