I find it interesting that we are able to push shell commands directly into awk.
Is there any documentation around how this works? Is this only supported with the 'print' statement?

Once I extract... (4 Replies)
How can I direct awk output to go nowhere? I can write the data to a file easy enough or print it on the screen. But for this particular command I don't actually want the data and I don't want to create a file. I just want the data discarded.

Hello everyone, I've suddenly gotten very interested in sed and awk (and enjoying it quite a bit too) because of a large conversion project that we're working on.

In the awk below the first sample MEV45 gets extracted from the html, but the subsequent MEV46 and MEV47 do not as they are not part of parse. I can not seem to add them to the code. Thank you very much @RudiC your awk is very nice :).

scha_resourcetype_get(1HA) Sun Cluster Commands scha_resourcetype_get(1HA)NAME
scha_resourcetype_get - access resource type information
SYNOPSIS
scha_resourcetype_get -O optag -T type
DESCRIPTION
The scha_resourcetype_get command accesses information about a resource type that is registered with the Resource Group Manager (RGM).
Use this command in shell script implementations of the callback methods for resource types that represent services that are controlled by
the RGM. This command provides the same information as the scha_resourcetype_get(3HA) C function.
Information is output by this command to the standard output (stdout) in formatted strings, as described in the scha_cmds(1HA) man page.
Output is a string or several strings that are output on separate lines. You can store the output in shell variables. You can also parse
the output by using the awk(1) command or other shell commands for further use by the script.
You need solaris.cluster.resource.read RBAC authorization to use this command. See the rbac(5) man page.
Authorized users can issue privileged Sun Cluster commands on the command line from the pfsh(1), pfcsh(1), or pfksh(1) profile shell. A
profile shell is a special kind of shell that enables you to access privileged Sun Cluster commands that are assigned to the Sun Cluster
Commands rights profile. A profile shell is launched when you run su(1M) to assume a role. You can also use pfexec(1) to issue privileged
Sun Cluster commands.
OPTIONS
The following options are supported:
-O optag Indicates the information to be accessed.
Note -
optag options, such as API_VERSION and BOOT, are not case sensitive. You can use any combination of uppercase and lowercase
letters when you specify optag options.
The following optag values retrieve the corresponding resource type properties. The value of the named property of the
resource's type is output.
API_VERSION
BOOT

IS_LOGICAL_HOSTNAME
