I know what is happening hopefully you can help me now:

-Two times a day the receiver from where I'm getting the data stops sending for a couple of seconds due to an internal cron job.

-Because of this my entire all the process of getting AIS sentences stops:
Code:
nc -ul -p 56045 -q -1 | awk -F: 'NF > 1 {print strftime("%d-%m-%Y %H:%M:%S"),$0;fflush();  }' > awk.txt 2>&1 &


but I'm listening forever in my nc sentences, so what is happeningż?

All the best

Name
       style - analyze surface characteristics of a document

Syntax
       style [-ml] [-mm] [-a] [-e] [-l num] [-r num] [-p] [-P] file...

Description
       The command analyzes the surface characteristics of the writing style of a document.  It reports on readability, sentence length and struc-
       ture, word length and usage, verb type, and sentence openers.  Because runs before looking at the text, formatting header files	should	be
       included  as  part  of  the  input.  The default macro package -ms may be overridden with the flag -mm.	The flag -ml, which causes to skip
       lists, should be used if the document contains many lists of non-sentences.  The other options are used to locate  sentences  with  certain
       characteristics.

Options
       -a Displays all sentences with their length and readability index.

       -e Displays all sentences that begin with an expletive.

       -l num
	  Displays all sentences longer than num.

       -ml
	  Skips lists in document.

       -mm
	  Overrides the default macro package -ms.

       -P Displays parts of speech of the words in the document.

       -p Displays all sentences that contain a passive verb.

       -r num
	  Displays all sentences whose readability index is greater than num.

Restrictions
       Use of non-standard formatting macros may cause incorrect sentence breaks.
