Sorry for the confusion

Let me give you a complete example what I am trying to achieve.

1. Below is the log file structure where I need 2,5 and 14th column of the logs after grepping through the linkId=1ddoic.

Log file structure:-

abc.com 20120829001415 127.0.0.1 app none11111 sas 0 0 N clk Mozilla/5.0 id=82c6a15ca06b2372c3b3ec2133fc8b14 referrer=google.com linkId=1ddoic

abc.com 20120829001416 127.0.0.1 dyn UD3BSAp8appncXlZ UD3BSAp8app4xHbz 0 0 N page Mozilla/5.0 id=82c6a15ca06b2372c3b3ec2133fc8b14 segments=

2. Now for the 1st log you can see I have invalid(none11111) 5th column. So I have to look for the actual 5th column value. 'id' column will help you to find that. So you have to run another grep based on the 'id' value so that you can find the actual 5th column in the same log file.
3. If you see the second log it has the exact matching 'id' value. So what I have to do I have to take the 5th column(UD3BSAp8appncXlZ) from the second log instead of the invalid one(none11111).

Output:-

20120829001415, UD3BSAp8appncXlZ, linkId=1ddoic

Note:- I have bunch of log files where I have to perform the above procedure. But I have to come up with a single file as output after grepping through all the log files.
It has a format like abc-2012-10-01_00000,abc-2012-10-01_00001.... etc.



Hope this time it makes clear.Smilie
Thanks for looking into it.

WATCHGNUPG(1)							 GNU Privacy Guard						     WATCHGNUPG(1)

NAME
watchgnupg - Read and print logs from a socket SYNOPSIS
watchgnupg [--force] [--verbose] socketname DESCRIPTION
Most of the main utilities are able to write their log files to a Unix Domain socket if configured that way. watchgnupg is a simple lis- tener for such a socket. It ameliorates the output with a time stamp and makes sure that long lines are not interspersed with log output from other utilities. This tool is not available for Windows. watchgnupg is commonly invoked as watchgnupg --force ~/.gnupg/S.log OPTIONS
watchgnupg understands these options: --force Delete an already existing socket file. --tcp n Instead of reading from a local socket, listen for connects on TCP port n. --verbose Enable extra informational output. --version Print version of the program and exit. --help Display a brief help page and exit. EXAMPLES
$ watchgnupg --force /home/foo/.gnupg/S.log This waits for connections on the local socket '/home/foo/.gnupg/S.log' and shows all log entries. To make this work the option log-file needs to be used with all modules which logs are to be shown. The value for that option must be given with a special prefix (e.g. in the conf file): log-file socket:///home/foo/.gnupg/S.log For debugging purposes it is also possible to do remote logging. Take care if you use this feature because the information is send in the clear over the network. Use this syntax in the conf files: log-file tcp://192.168.1.1:4711 You may use any port and not just 4711 as shown above; only IP addresses are supported (v4 and v6) and no host names. You need to start watchgnupg with the tcp option. Note that under Windows the registry entry HKCUSoftwareGNUGnuPG:DefaultLogFile can be used to change the default log output from stderr to whatever is given by that entry. However the only useful entry is a TCP name for remote debugging. SEE ALSO
gpg(1), gpgsm(1), gpg-agent(1), scdaemon(1) The full documentation for this tool is maintained as a Texinfo manual. If GnuPG and the info program are properly installed at your site, the command info gnupg should give you access to the complete manual including a menu structure and an index.
