Hi,
I'm trying to compare the value in a field to the value in a variable using awk. This works:
awk '$7 == "101"'but this is what I want (and it doesn't work):
value=101
awk '$7 == "$value"'
Any help or insight on this would be great. Thanks in advance. (1 Reply)

wrsmconf
wrsmconf(1M) System Administration Commands wrsmconf(1M) NAME
wrsmconf - manage WCI RSM controller configurations SYNOPSIS
/usr/platform/sun4u/sbin/wrsmconf create -c controller_id -f config_file wrsmconf initial -f config_file [ -c controller_id] wrsmconf remove [ -c controller_id] wrsmconf topology [ -c controller_id] wrsmconf dump -c controller_id -f config_file DESCRIPTION
wrsmconf provides a means to create, install, retrieve, and remove configurations for WCI remote shared memory (RSM) controllers. OPTIONS
The following options are supported: create -c controller_id -f config_file Create a set of per-node configurations for the specified controller and store them to the file config_file. The created file contains a per-node configuration for each node specified in the input for the specified controller. The file has a checksum on it and cannot be modified directly. This file can be used in a wrsmconf initial call on each node to install the node's configuration into the local driver. A list of nodes and WCI devices connected to those nodes is read from standard input. For each connected pair of links, specify the nodename (uname -n), safari port id, and link number on both sides of the connection. The format of the information looks like this: <nodename>.<wrsm-portid>.<linkno>=<nodename>.<wrsm-portid>.<linkno> <nodename>.<wrsm-portid>.<linkno>=<nodename>.<wrsm-portid>.<linkno> This interface is intended for installing configurations for testing (such as for SunVTS). Only direct-connect, non-striped configura- tions for 1 to 3 nodes can be specified. FM node ids and RSM hardware addresses are assigned to the specified nodes contiguously and in order starting from 0. initial -f config_file [-c controller_id] Install the configuration for the local node stored in the file config_file into the driver as the initial configuration for the speci- fied controller. This command fails under the following circumstances: o If controller_id is specified and the configuration in the file is not for the specified controller. o If the file does not contain a valid configuration for the local node or if the checksum in the file shows it has been modified. o If a configuration has already been installed for the controller. If this happens, use wrsmconf remove to remove the existing con- figuration. remove [ -c controller_id ] Disable communication through the installed configuration for all controllers or the specified controller and remove the configura- tion(s) from the driver. topology -c controller_id For each installed controller (or for the specified controller), print to stdout the set of nodes this controller is configured to reach, including the nodename, FM node id, and RSM hardware address for each node. The following is example output: FM Node ID Node Name Controller Instance Controller HW Addr 0 hpc00 0 101 0 hpc00 1 333 1 hpc01 0 102 1 hpc01 1 54 1 hpc01 2 34 2 hpc03 0 103 2 hpc03 1 103 2 hpc03 2 103 dump -c controller-id -f config_file Fetch the installed configuration for the specified controller from the driver and store it into the file config_file along with a checksum to protect the data. This configuration can later be installed with the command wrsmconf initial. EXIT STATUS
This command returns 0 on successful completion, and a non-zero value if an error occured. ATTRIBUTES
