how about in a case like the below:

Code:
HOST-RESOURCES-MIB::hrSWRunPath.18121 = STRING: "/usr/local/lib/sa/sadc" ---- HOST-RESOURCES-MIB::hrSWRunPath.18144 = STRING: "/usr/vendor/jdk15/bin/java" ---- HOST-RESOURCES-MIB::hrSWRunPath.20634 = STRING: "/usr/local/bin/ntpd" ---- HOST-RESOURCES-MIB::hrSWRunPath.21659 = STRING: "//usr/sbin/asterisk" ---- HOST-RESOURCES-MIB::hrSWRunPath.29595 = STRING: "/usr/bin/perl"

in the above, the fields are separated by "----".

what if I want to grep out just the field that has the entire string HOST-RESOURCES-MIB::hrSWRunPath.18144 = STRING: "/usr/vendor/jdk15/bin/java in it?

reason why i'm asking is that, the value /usr/vendor/jdk15/bin/java is not always known. what is known is the "HOST-RESOURCES-MIB::hrSWRunPath.18144". So i run into problems trying to grab the entire string associated with that before the ---- delimiter.

snmpdf

SNMPDF(1)							     Net-SNMP								 SNMPDF(1)

NAME

       snmpdf - display disk space usage on a network entity via SNMP

SYNOPSIS

       snmpdf [COMMON OPTIONS] [-Cu] AGENT

DESCRIPTION

       snmpdf  is  simply  a  networked  version  of  the  typical  df	command.   It checks the disk space on the remote machine by examining the
       HOST-RESOURCES-MIB's hrStorageTable or the UCD-SNMP-MIB's dskTable.  By default, the hrStorageTable is preferred as it  typically  contains
       more information.  However, the -Cu argument can be passed to snmpdf to force the usage of the dskTable.

       AGENT  identifies  a  target SNMP agent, which is instrumented to monitor the gievn objects.  At its simplest, the AGENT specification will
       consist of a hostname or an IPv4 address.  In this situation, the command will attempt communication with the agent, using UDP/IPv4 to port
       161 of the given target host. See the snmpcmd(1) manual page for a full list of the possible formats for AGENT.

       See the snmpd.conf(5) manual page on setting up the dskTable using the disk directive in the snmpd.conf file.

OPTIONS

       COMMON OPTIONS
	       Please see snmpcmd(1) for a list of possible values for COMMON OPTIONS as well as their descriptions.

       -Cu     Forces  the command to use dskTable in mib UCD-SNMP-MIB instead of the default to determine the storage information. Generally, the
	       default use of hrStorageTable in mib HOST-RESOURCES-MIB is preferred because it typically contains more information.

EXAMPLES

       % snmpdf -v 2c -c public localhost
