Top Forums Shell Programming and Scripting Match text to lines in a file, iterate backwards until text or text substring matches, print to file Post 303038410 by Chubler_XL on Tuesday 3rd of September 2019 12:07:41 AM

Apart from showing us your attempts at this problem, could you also indicate if the order of records in the output file is important?

The problem description seems to indicate that a direct match record, when available, should be listed first and then other matches should be displayed in the same order as they appear in file1.txt.

However if the order of records in the output file is unimportant, the solution can be simplified a fair bit.

Name
       trpt - transliterate protocol trace

Syntax
       trpt [ -a ] [ -s ]  [ -t ] [ -j ] [ -p hex-address ] [ system [ core ] ]

Description
       The command interrogates the buffer of TCP trace records created when a socket is marked for debugging and prints a readable description of
       these records.

Options
       When no options are supplied, prints all the trace records found in the system grouped according to TCP connection protocol  control  block
       (PCB).  The following options may be used to alter this behavior:

       -s     In addition to the normal output, prints a detailed description of the packet sequencing information.

       -t     In addition to the normal output, prints the values for all timers at each point in the trace.

       -j     Gives a list of the protocol control block addresses for which there are trace records.

       -p     Shows only trace records associated with the protocol control block whose address follows.

       -a     In addition to the normal output, prints the values of the source and destination addresses for each packet recorded.

       The recommended use of is to isolate the problem and enable debugging on the socket(s) involved in the connection.  Find the address of the
       protocol control blocks associated with the sockets using the -A option to Then run with the -p option, supplying the  associated  protocol
       control block addresses.  If there are many sockets using the debugging option, the -j option may be useful in checking to see if any trace
       records are present for the socket in question.

       If debugging is being performed on a system or core file other than the default, the last  two  arguments  may  be  used  to  supplant  the
       defaults.

Diagnostics
       no namelist
       The system image does not contain the proper symbols to find the trace buffer.

       Other diagnostic messages are self-explanatory.
