I've also used `jobs' under /bin/sh to do this as follows:
#!/bin/sh
some_command &
echo " some_command run "
job_pids `jobs`
echo ${job_pids} | awk -- '{ print $2; }' > /tmp/some_command.pid
kill -9 `cat /tmp/some_command.pid
Or I guess you could replace the last two lines with:
pid=`echo ${job_pids} | awk -- '{ print $2; }'`
kill -9 $pid
