you can use tools like md5sum, cksum, sha1 etc to monitor your file. an alternative in Perl
Code:
#!/usr/bin/perl
use Digest::MD5 ;
my $file2monitor = "file";
sub getmd5 {
    my $file = $_[0];    
    open(FH,"<",$file) or die "Cannot open file: $!\n";    
    binmode(FH);
    my $md5 = Digest::MD5->new;
    return $md5->addfile(*FH)->hexdigest;    
    close(FH);
}
my $original_sum = getmd5 $file2monitor;
while (1){
    my $getcksum = getmd5 $file2monitor;
    if ( $getcksum ne $original_sum ){
       print "File $file2monitor changed:\n";
    }

dbus-monitor(1) 					      General Commands Manual						   dbus-monitor(1)

NAME
dbus-monitor - debug probe to print message bus messages SYNOPSIS
dbus-monitor [--system | --session | --address ADDRESS] [--profile | --monitor] [watch expressions] DESCRIPTION
The dbus-monitor command is used to monitor messages going through a D-Bus message bus. See http://www.freedesktop.org/software/dbus/ for more information about the big picture. There are two well-known message buses: the systemwide message bus (installed on many systems as the "messagebus" service) and the per-user-login-session message bus (started each time a user logs in). The --system and --session options direct dbus-monitor to monitor the system or session buses respectively. If neither is specified, dbus-monitor monitors the session bus. dbus-monitor has two different output modes, the 'classic'-style monitoring mode and profiling mode. The profiling format is a compact for- mat with a single line per message and microsecond-resolution timing information. The --profile and --monitor options select the profiling and monitoring output format respectively. If neither is specified, dbus-monitor uses the monitoring output format. In order to get dbus-monitor to see the messages you are interested in, you should specify a set of watch expressions as you would expect to be passed to the dbus_bus_add_match function. The message bus configuration may keep dbus-monitor from seeing all messages, especially if you run the monitor as a non-root user. OPTIONS
--system Monitor the system message bus. --session Monitor the session message bus. (This is the default.) --address ADDRESS Monitor an arbitrary message bus given at ADDRESS. --profile Use the profiling output format. --monitor Use the monitoring output format. (This is the default.) EXAMPLE
Here is an example of using dbus-monitor to watch for the gnome typing monitor to say things dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'" AUTHOR
dbus-monitor was written by Philip Blundell. The profiling output mode was added by Olli Salli. BUGS
Please send bug reports to the D-Bus mailing list or bug tracker, see http://www.freedesktop.org/software/dbus/ dbus-monitor(1)
