-#!/bin/sh
-# This script is designed to be used by Nagios. It checks for the availability of both Microsoft SQL Server 7 and 2000.
-#
-# Requirements:
-#
-# FreeTDS 6.0+ (http://www.freetds.org/)
-#
-# It was written by Tom De Blende (tom.deblende@village.uunet.be) in 2003.
-#
-# Version 1.0.
-# Version 1.1: Rewritten the initial script so that it not only works from the CLI but also from within Nagios. Always helpful...
-# Version 1.2: Grouped output so things look a bit better.
-# Version 2.0: Rewritten the plugin to support version 6.0+ of FreeTDS.
-# Removed sqsh requirement as version 6.0+ of FreeTDS now offers its own CLI client: tsql.
-# Older versions of FreeTDS are no longer supported.
-#
-#
-# You might want to change these values:
-
-tsqlcmd=`which tsql`
-catcmd=`which cat`
-grepcmd=`which grep`
-rmcmd=`which rm`
-mktempcmd=`which mktemp`
-wccmd=`which wc`
-sedcmd=`which sed`
-trcmd=`which tr`
-uniqcmd=`which uniq`
