#!/bin/sh

LOCKFILE=/var/lock/sphinx.cron.lock
INDEXER_CONF=/usr/local/etc/sphinx.conf

# the lockfile is not meant to be perfect, it's just in case the

[ -f $LOCKFILE ] && exit 0

trap "{ rm -f $LOCKFILE ; exit 255; }" EXIT

touch $LOCKFILE

cd /usr/local/bin/ #(NOTE: this should be where indexer is located)

DELTAS_ONLY_LINE: ./indexer --config $INDEXER_CONF --rotate YOUR_POST_INDEX_DELTA YOUR_THREAD_INDEX_DELTA >/dev/null 2>&1
OR
FULL_INDEX_LINE ./indexer --all --rotate --config $INDEXER_CONF  >/dev/null 2>&1

exit 0

You could also replace ">/dev/null 2>&1" with "| mail -s "Sphinx Report" YOUR_EMAIL_HERE" to get an email of the output.

You should use lockrun instead, is way more robust then a shell script.
