Merging between streams in Perforce using Command line rather than P4V

I need to merge the streams using commands in P4. can anyone help me with this? the two streams are parent child streams. I need to merge down from parent to child.

I'm typing this from memory, without actually trying it, but I think this is pretty close:

1. Switch your client workspace to the child stream, since that is the target of the merge: p4 client -s -S child
2. Sync your client, to make sure you're building and testing with the latest files: p4 sync
3. Merge the parent stream's changes into your child stream: p4 merge
4. Resolve any conflicts: p4 resolve
5. Build and test, to confirm that you're happy with the results
6. Submit the merged code to the child stream: p4 submit

Of course, make sure that you're working with the correct client workspace, as the correct user, etc., by running p4 set before you start this process, to look at your P4CLIENT, P4USER, etc. settings.
