$0 | means : current line |
~ | means : contains the pattern |
d1 | your variable will be interpreted so the ~ operator will try to find the contend of your d1 variable in $0 |
$0~d1 | will search for the content of variable d1 into the current line |
$0~/d1/ | with this notation, awk will parse what is inside the / / as being a regular experession (using the extended character set) so in this case, it will search for the litteral string "d1" into the current line |
This code use p as a flag. The flag is turned on and off with 1 and 0.
By default a non zero value means 'TRUE' otherwise 'FALSE', if the last awk instruction (here: p ) is true, then the current line is printed, if false, nothing is printed.
This is the default behaviour of awk for displaying stuff until another behaviours is explicitly coded with print/printf/getline/next or some other instruction that may have an influence on the output.

scha_resourcetype_get
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

-T type Is the name of a resource type that is registered for use by the RGM cluster facility.
EXIT STATUS
