Thanks for the reply.

Is there a way to put a validation in the linux script which will do the following,

Quote:
find $sourcepath/*datevalue_filename* -type f -newer /tmp/start -not -newer /tmp/end > $destinationpath/wcc_cpmg_nt_bus_gs.txt
In the below FOR Loop, is there a way to put a logic to check whether the file *datevalue_filename* already exists in the $destinationpath.

Quote:
for name in `cat $destinationpath/wcc_cpmg_nt_bus_gs.txt`
do
cp $name $COMMON_INBOX
echo $name;
done
If the date_filename is available, we shouldnt copy the file again.

Thanks Much,
Freddie

ppmtopgm

ppmtopgm(1)						      General Commands Manual						       ppmtopgm(1)

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.
