AWK syntax question
Hi,

Have to check file names in some given directory.

SO, What is the right syntax here:
Quote:

>object_list="CUSTOMER ADDRESS TELEPHONE"
>file_list=`ls $DATA_PATH | awk -F"_" 'NF==5 && $1=="'$vendor'" && $2=="'$source'" && *$3*=="'$object_list'" {print $0}'`
*$3*=="'$object_list'" - just wanted to check if $3 is in the object_list.

And also, Do I need so many quotes around?

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.
