The status (the NOERROR in this case) actually serves the purpose of saying that the connection to the DNS server is ok. I wanted a way to correctly split this ressource record so i could extract every field if i wanted to.... I could then use this to extract every DNS message NOERROR, NXDOMAIN, SERVFAIL, etc treat them accordingly.
What if i could keep my RS the same BUT use an empty line as a split delimiter?
That way i could have block[1] like this:
And so on and so on so i would know that if block[4] exist i have a failed update?
I have a file that contains the output of the ls -iR command, something like this:
./results:
2504641011 result_1410 2500957642 result_525
2504641012 result_1425 2500957643 result_540
./tests/1:
2500788755 1 2500788743 1000
./tests/2:
2500788759 3 2500788758 999

I need to parse the following out put and determine if the USB is a DISK and whether or not it's External.
If an HBA line contains "USB" then does the next line contain
"DISK" and "External".

tsig-keygen
DDNS-CONFGEN(8) BIND9 DDNS-CONFGEN(8)NAME
ddns-confgen - ddns key generation tool
SYNOPSIS
tsig-keygen [-a algorithm] [-h] [-r randomfile] [name]
ddns-confgen [-a algorithm] [-h] [-k keyname] [-q] [-r randomfile] [-s name | -z zone]
DESCRIPTION
tsig-keygen and ddns-confgen are invocation methods for a utility that generates keys for use in TSIG signing. The resulting keys can be
used, for example, to secure dynamic DNS updates to a zone or for the rndc command channel.
When run as tsig-keygen, a domain name can be specified on the command line which will be used as the name of the generated key. If no name
is specified, the default is tsig-key.
When run as ddns-confgen, the generated key is accompanied by configuration text and instructions that can be used with nsupdate and named
when setting up dynamic DNS, including an example update-policy statement. (This usage similar to the rndc-confgen command for setting up
command channel security.)
Note that named itself can configure a local DDNS key for use with nsupdate -l: it does this when a zone is configured with update-policy
local;. ddns-confgen is only needed when a more elaborate configuration is required: for instance, if nsupdate is to be used from a remote
system.
OPTIONS -a algorithm
Specifies the algorithm to use for the TSIG key. Available choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384 and
hmac-sha512. The default is hmac-sha256. Options are case-insensitive, and the "hmac-" prefix may be omitted.
-h
Prints a short summary of options and arguments.
-k keyname
Specifies the key name of the DDNS authentication key. The default is ddns-key when neither the -s nor -z option is specified;
otherwise, the default is ddns-key as a separate label followed by the argument of the option, e.g., ddns-key.example.com. The key
name must have the format of a valid domain name, consisting of letters, digits, hyphens and periods.
-q
(ddns-confgen only.) Quiet mode: Print only the key, with no explanatory text or usage examples; This is essentially identical to
tsig-keygen.
-r randomfile
Specifies a source of random data for generating the authorization. If the operating system does not provide a /dev/random or
equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file
containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used.
-s name
(ddns-confgen only.) Generate configuration example to allow dynamic updates of a single hostname. The example named.conf text shows
how to set an update policy for the specified name using the "name" nametype. The default key name is ddns-key.name. Note that the
"self" nametype cannot be used, since the name to be updated may differ from the key name. This option cannot be used with the -z
option.
-z zone
(ddns-confgen only.) Generate configuration example to allow dynamic updates of a zone: The example named.conf text shows how to set an
update policy for the specified zone using the "zonesub" nametype, allowing updates to all subdomain names within that zone. This
option cannot be used with the -s option.
