@girish: Thanks for the reply. I am trying to understand your logic and get back to you once done.

@danmero: I really dont know how to put forward this in posts and as i felt this is bit tedious to explain through posts, i am pasting what actually i am trying to do.
This is what i am trying to do...
I have a file(mainfile) with the below format:
Code:
Date:Warning: client clientname1, grp grpouname1, sometext
Date:Warning: client clientname2, grp grpouname2, sometext
Date:Warning: client clientname3, db dbname3,(sometext)
Date:Warning: client clientname4, db dbname4,(sometext)
.
.
.
.

I am writing a script which will run for every 5 min read the content of main file and update a file(pcfile) to contain the client name (entire name as in mainfile ) along with the count of how many times the line has been repeated.
i have divided the script into following stages
1. Check the mainfile every time the script runs and store only the updated lines in that. Say this file as tmpfile.
2.I will compare each and every line in the tmpfile with the file called failedfile. Comparison will be done with the below format:
clientname1, grp grpouname1
clientname2, db dbname2

about failedfile:
----------------
failed file contains the filtered entries of mainfile. For the first run of script it will be empty.
Comparision starts:
3.
a. If the first comparision(line1) is positive, i will assign a counter,increment it and send the line with counter to pcfile. Keep in mind that each and every line is a different comparision and requires a seperate counter. Now append the line to pcfile and failedfile. For the next time the script runs, if the script doesn't find this line in tmpfile, the counter should be reset.
b. else, append the line to pcfile and failedfile.
4. Now remove the tmpfile.
----Script ends-----


Right now i am struggling with 3rd point.

Cheers,
Sai

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.

KEYWORDS
