I don't think snmp tables have any defined order. I don't even know if the index for a particular resource is guaranteed to be stable across filesystem dismount/remounts. Something like this should work: snmptable -Cf : blue hrStorageTable | grep :/var: | awk -F : '{print $4 * $5}' I use something similar in a script to graph disk usage in mrtg. It sould be really nice if snmptable had a built-in flag to print a particular cell from a table, though. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
