Right.  When you run it from the Nagios user's shell, you have a bunch
of environment variables set, but when NRPE runs it it's probably pretty
environmentless, like a script run by crond.  


`env - [commands]` simulates how crond or nrpe or xinetd will run your
script so it's a good trick for problems like this.

The problem was that xinetd has its own environment vars that were not 
being passed until I told it to do so. Now I can run './check_nrpe -H -c check_db' with nrpe config alias as:

check_db=/usr/local/nagios/libexec/check_oracle --db DBPRD

but I cannot have the alias as:

check_db=/usr/local/nagios/libexec/check_oracle --db $ORACLE_SID

it passes an empty variable to the program. but only if it's run 
remotely from nagios very strange. It works when logged in as nagios 
running locally. I'm not even attempting to pass any $ARGS$.
