I guess I still don't understand what output you're trying to produce.
Everything in the second column of the output you showed us in the image you included in post #5 in this thread is identical to the data to the first column of the output in that same image with the possible exception of the filename you have in the date field (which is chopped off because you didn't show us the entire image). In the first post you said you wanted to delete output lines where everything matched, but the output you've shown us has everything matching with nothing deleted???
Please try once more to clearly explain what you are trying to do. It is hard to help you come up with a solution to your problem if we can't figure out what you're trying to do!

ximtoppm
ximtoppm(1) General Commands Manual ximtoppm(1)
NAME
ximtoppm - convert an Xim file into a portable pixmap
SYNOPSIS
ximtoppm [--alphaout={alpha-filename,-}] [ximfile]
DESCRIPTION
Reads an Xim file as input. Produces a portable pixmap as output. The Xim toolkit is included in the contrib tree of the X.V11R4 release.
OPTIONS
--alphaout=alpha-filename
ximtoppm creates a PGM (portable graymap) file containing the alpha channel values in the input image. If the input image doesn't
contain an alpha channel, the alpha-filename file contains all zero (transparent) alpha values. If you don't specify --alphaout,
ximtoppm does not generate an alpha file, and if the input image has an alpha channel, ximtoppm simply discards it.
If you specify - as the filename, ximtoppm writes the alpha output to Standard Output and discards the image.
Actually, an Xim image can contain an arbitrary fourth channel -- it need not be an Alpha channel. ximtoppm extracts any fourth
channel it finds as described above; it doesn't matter if it is an alpha channel or not.
See pnmcomp(1) for one way to use the alpha output file.
All options can be abbreviated to their shortest unique prefix.
