Hi Scottn,
Thanks for ur very quick reply...
Quote:
PROGRAM_NAME=SOME_PROGRAM_NAME
is the original value.
But What I want exactly is,
The original value should be as same as before. But also some more content should be appended to it. So for that I hope it should recognize the first ) after PROGRAM_NAME=... and then append _VERY_USEFUL to that before that first occurance of the ).
And the value of the PROGRAM_NAME may vary depending on the server in which we are using.
Hope you got my question now.

Also I want to make the changes permanent in the modifying file.
Please help me...

NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
