Let's back up a moment and ask why you are doing this from scripts, because this feels like an XY problem, see: http://people.apache.org/~hossman/#xyproblem <http://people.apache.org/~hossman/#xyproblem> What are you trying to accomplish by swapping cores on the master and slave?
Solr 1.4 has configuration-based replication, are you using 1.4? This version of Solr automatically, upon replication, switches to the updated index. You can trigger a replication either by configuring the polling interval on the slave or by sending the proper HTTP request to the slave. See: http://wiki.apache.org/solr/SolrReplication#HTTP_API So, it seems like taking charge of swapping cores may be more work than you really need to do. Of course, if you're on a different version of Solr, this is irrelevant.
