Here's something for you...

Code:
#! /bin/sh

# This is the log that will be monitored. 
# If any changes occur to this, then take appropriate action.
MONITORED_LOG=/tmp/goreb.log

# We will need this log to see whether any changes occured to /tmp/goreb.log
TEMP_LOG=/tmp/.goreb.log.1

# This is a 1-time command i.e. create the log file if it does nto exist.
[ ! -f $TEMP_LOG ] && touch -r $MONITORED_LOG $TEMP_LOG

[ $MONITORED_LOG -nt $TEMP_LOG ] && echo "$MONITORED_LOG is newer than $TEMP_LOG. Carry out your required operations"

# Update $TEMP_LOG with the new modified date of $MONITORED_LOG
touch -r $MONITORED_LOG $TEMP_LOG

torrus_monitor

TORRUS_MONITOR(8)						      torrus							 TORRUS_MONITOR(8)

NAME

       monitor - Torrus Monitor.

SYNOPSIS

       torrus monitor --tree=TREENAME [options...]

DESCRIPTION

       This command starts the Monitor process for the tree TREENAME. By default it forks into a daemon, sets the log output file to
       /var/log/torrus/monitor.TREENAME.log, performs one monitoring cycle, and sleeps until the next cycle is scheduled. In daemon mode the log
       file can be reopened by sending it a SIGHUP signal.

OPTIONS

       --nodaemon
	   Prevents the process from becoming a daemon and sets the log to STDERR.

       --runonce
	   Instructs the script to run once and exit. Implies --nodaemon.

       --delay=N
	   Makes the daemon sleep for N minutes before starting the first cycle.  This would happen on the daemon startup and also after each
	   configuration recompilation.  For example, when monitor and collector start simultaneously, the collector needs some time to retrieve
	   the data being monitored.

       --debug
	   Sets the log level to debug.

       --verbose
	   Sets the debug level to info.

       --help
	   Displays a help message.

FILES

       /etc/torrus/conf/torrus-siteconfig.pl
	   Torrus site configuration script.

       /var/log/torrus/monitor.TREENAME.log
	   Monitor's log for the tree TREENAME.
