Hello looney,

One more query, there will be around 10 million records in source file
Yes, you could do division by int(NR/1000000) to make only 10 files as per your requirement. You could double check it as I don't have 10 million line Input_file with me, so logic is simple like if you wanted to make 10 files just divide the total number of lines by the number of files which you need and you will get per file total number of lines then.

Do i need to close it also. ?
Yes, we do need to close the files for example close(f) where f is a variable for the filename.
I hope this helps you.

Thanks,
R. Singh

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
