Okay, what you're going to need is a list of structures. (You *could*
cheat and say list[0] is the RTR and the rest are the OID's, which is
how it would get stored in memory anyway, but you're still going to need
a list of lists.) BASH doesn't do this well. Especially when you're
trying to write it as a stream; this is NOT a one-pass operation.
You did:
for i in $RTR
do
for n in $oid
do echo $i,`$snmp $i $n|cut -f2 -d:` >> $LOG
done
done
Thankfully, your output is text, so I can cheat. (Bash IS good at
mucking about with strings, especially aided by newer versions of
grep(1) with the -o option... but that's not even necessary here.)
for i in $RTR
do
RESULT=$RTR
for i in $oid
do
RESULT="${RESULT},`$snmp $i $n|cut -f2 -d:`"
done
echo $RESULT >> $LOG
done
Essentially, stuff comma-then-next-item onto the end of $RTR until we
run out of OID's, then output that line.
Hopefully all values are unique, otherwise you're back to square one...
Hope this helps,
