[etch-users] When running a script, how to properly indicate an error

[Johnston, N. <Nat...@ca...>]

The Powers That Etch,

I have a configuration I am working on that will set up /etc/snmpd.conf on some of my hosts.  In order for me to properly set the SNMP trap destinations using the "trapsink" directive, I need to call out to an external resource.  In the event that the external resource call fails for whatever reason, I do not want Etch to take action for that run.  What is the proper way in my script to indicate "An error occurred, do not etch this particular /etc/snmpd.conf" in a graceful manner?
