not sure exactly what you want here, but here an example which might help:

  find / > out &
  pid=$!
  sleep 4; kill $pid

this will find as many files as it can in about ~ 4 seconds,
then kill the find process.

The bash "info" doc is helpful, I always forget which funny variable is which,
you can type:

  info bash var

to list all the variables, this one $! is one of the "special parameters" at
the top.

You may need to install the "bash-doc" package first.

hope this helps,
