daemon process gives real time
It seems that you would be better served to create a daemon to control this process.
You could tailor it to notify you when the string you want appears and email or beep you. You should have a template of one on your system or you can copy from a simple one in a directory similar to /sbin/init.d/template.
cp template myscript
You will need to add a kill and start link in your rc directories for it to startup a boot time.
ln -s myscript /sbin/rc3.d/S400myscript
ln -s myscript /sbin/rc1.d/K400myscript
Hope this helps!

yppasswdd
yppasswdd(4) File Formats yppasswdd(4)
NAME
yppasswdd - configuration file for rpc.yppasswdd (NIS password daemon)
SYNOPSIS
/etc/default/yppasswdd
DESCRIPTION
The yppasswdd file contains a parameter that modifies the behavior of the rpc.yppasswdd(1M) daemon.
The yppasswdd file contains a single parameter:
#check_restricted_shell_name=1
By default in the current release, this line in yppasswdd is commented out. If you uncomment the line, when a user attempts to change his
default shell using `passwd -r nis -e` (see passwd(1)), the rpc.yppasswdd daemon checks whether the name of the user's current shell
begins with an 'r'. rpc.yppasswdd considers any shell whose name begins with an 'r' (for example, rcsh) to be a restricted shell. If a
user's shell does begin with 'r', his attempt to change from the default shell will fail.
If the line in the yppasswdd file is commented out (the default), the rpc.yppasswdd daemon does not perform the restricted shell check.
The yppasswdd file is editable only by root or a member of the sys group.
