I've written an awk one-liner to parse a stream of real-time data. I invoke a program that gives me output from which I extract a few columns, perform some simple calculations, and then stream that data into a portal using an http string. It's tricky because I have to run it every second to parse the data I need, but it works.
My question is about adding in an if/then statement. I need to check if the output of Ntripclient2.py actually has the data I need. If it doesn't I need to move on, not parse it, and run the awk one-liner again until I actually get the data I need. The problem is I end up parsing an error message, and it bogs down my portal.
I need to check NR==13, if($5==0) skip the parse step and keep going. Does that make sense?
I have limited bandwidth in my apartment and no cable TV service. I was wondering if it is possible to write a script that would download the video data from my favorite TV shows (legally... many networks post their videos online for free) while I sleep, so that later I can watch them on my TV...

I need to parse some continuous output from a program (i.e. aScript.py) into a portal that uses curl. I've written a simple awk one-liner to parse the information that is output from aScript.py, but I'm not able to execute it. I can succeed with just one line of the output from aScript.py: echo...

mailq
mailq(1) User Commands mailq(1)NAME
mailq - print the mail queue
SYNOPSIS
/usr/bin/mailq [-Ac] [-q subarg] [-v]
DESCRIPTION
The mailq utility displays a summary of the mail messages queued for future delivery.
The first line displayed for each mail message shows the internal identifier used on this host for the message, the size of the message in
bytes, the date and time the message was accepted into the queue, and the envelope sender of the message. The second line of the display
shows the error message that caused this message to be retained in the queue. This line will not be displayed if the message is being pro-
cessed for the first time.
The mailq utility used to be identical to sendmail -bp. Now it checks for the authorization attribute, solaris.mail.mailq. If the check for
the invoking user succeeds, sendmail -bp is executed with the remaining argument vector. Otherwise, an error message is printed. This
authorization attribute is by default enabled for all users. It can be disabled by modifying the Basic Solaris User entry in prof_attr(4).
OPTIONS
The following options are supported:
-Ac Like sendmail(1M), this flag tells mailq to use submit.cf rather than sendmail.cf even if the operation mode does
not indicate an initial mail submission. This will result in the client queue /var/spool/clientmqueue being displayed
rather than the default server queue /var/spool/mqueue.
-qp[time] Similar to -qtime, except that instead of periodically forking a child to process the queue, sendmail forks a single per-
sistent child for each queue that alternates between processing the queue and sleeping. The sleep time is given as the
argument. The sleep time default is 1 second. The process will always sleep at least 5 seconds if the queue was empty in
the previous queue run.
-qf Processes saved messages in the queue once and does not fork(), but runs in the foreground.
-qG name Processes jobs in the queue group called name only.
-q[!]I substr Limits processed jobs to those containing substr as a substring of the queue id, or not when ! is specified.
-q[!]R substr Limits processed jobs to those containing substr as a substring of one of the recipients, or not when ! is specified.
-q[!]S substr Limits processed jobs to those containing substr as a substring of the sender, or not when ! is specified.
-v Prints verbose information. This adds the priority of the message and a single character indicator (+ or blank) indicating
whether a warning message has been sent on the first line of the message. Additionally, extra lines may be intermixed with
the recipients that indicate the "controlling user" information. This shows who will own any programs that are executed on
behalf of this message and the name of the alias this command is expanded from, if any.
EXIT STATUS
0 Successful completion.
>0 An error occurred.
