@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

gllinestipple

GLLINESTIPPLE(3G)						   OpenGL Manual						 GLLINESTIPPLE(3G)

NAME

       glLineStipple - specify the line stipple pattern

C SPECIFICATION

       void glLineStipple(GLint factor, GLushort pattern);

PARAMETERS

       factor
	   Specifies a multiplier for each bit in the line stipple pattern. If factor is 3, for example, each bit in the pattern is used three
	   times before the next bit in the pattern is used.  factor is clamped to the range [1, 256] and defaults to 1.

       pattern
	   Specifies a 16-bit integer whose bit pattern determines which fragments of a line will be drawn when the line is rasterized. Bit zero
	   is used first; the default pattern is all 1's.

DESCRIPTION

       Line stippling masks out certain fragments produced by rasterization; those fragments will not be drawn. The masking is achieved by using
       three parameters: the 16-bit line stipple pattern pattern, the repeat count factor, and an integer stipple counter s.

       Counter s is reset to 0 whenever glBegin() is called and before each line segment of a glBegin()(GL_LINES)/glEnd() sequence is generated.
       It is incremented after each fragment of a unit width aliased line segment is generated or after each i fragments of an i width line
       segment are generated. The i fragments associated with count s are masked out if

       pattern bit s factor % 16

       is 0, otherwise these fragments are sent to the frame buffer. Bit zero of pattern is the least significant bit.

       Antialiased lines are treated as a sequence of 1 x width rectangles for purposes of stippling. Whether rectangle s is rasterized or not
       depends on the fragment rule described for aliased lines, counting rectangles rather than groups of fragments.

       To enable and disable line stippling, call glEnable() and glDisable() with argument GL_LINE_STIPPLE. When enabled, the line stipple pattern
       is applied as described above. When disabled, it is as if the pattern were all 1's. Initially, line stippling is disabled.

ERRORS

       GL_INVALID_OPERATION is generated if glLineStipple is executed between the execution of glBegin() and the corresponding execution of
       glEnd().

ASSOCIATED GETS

       glGet() with argument GL_LINE_STIPPLE_PATTERN

       glGet() with argument GL_LINE_STIPPLE_REPEAT

       glIsEnabled() with argument GL_LINE_STIPPLE
