[c-nsp] EEM applets and conditional statements

[Justin Shore]

I'm having trouble figuring out how to use the conditional capabilities 
of EEM applets to do something fairly simple.  I'd like to check for 
DHCP conflicts on a schedule and if any exist I'd like to generate a 
syslog message and send an email.  What I can't figure out how to do is 
parse the output of 'sh ip dh con' and if then perform an action if 
there are any conflicts (ie, more than just the single header line in 
the output).  I've gone through some of the EEM community scripts but 
they all seem to be full blown TCL scripts.  I'm thinking that I can 
handle this with a simple applet.  The applets have if, for, and while 
capabilities but I haven't figured out how to apply them to parsing 
command output?

Any suggestions or pointers?  Example scripts that demonstrate how to 
use the EEM logic capabilities would be fine too.  I can build off that 
to do what I need.

Thanks
