shell commands and awk

Hi RudiC,

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?

e.g.
Code:
awk 'NR==1 {print; next} {print | "sort -Vrk5"}'

Thanks.

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 FAILOVER FINI INIT INIT_NODES INSTALLED_NODES IS_LOGICAL_HOSTNAME IS_SHARED_ADDRESS MONITOR_CHECK MONITOR_START MONITOR_STOP PKGLIST POSTNET_STOP PRENET_START RESOURCE_LIST RT_BASEDIR RT_DESCRIPTION RT_SYSTEM RT_VERSION SINGLE_INSTANCE START STOP UPDATE VALIDATE -T type Is the name of a resource type that is registered for use by the RGM cluster facility. EXIT STATUS
The following exit values are returned: 0 The command completed successfully. nonzero An error occurred. Failure error codes are described scha_calls(3HA). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscdev | +-----------------------------+-----------------------------+ |Interface Stability |Stable | +-----------------------------+-----------------------------+ SEE ALSO
