If I understand what you're trying to do, and I'm not sure that I do (since you didn't supply any sample input that would cause anything to be output), you might want to try the following:
If you really want the leading space before the list of arguments passed to prying.sh remove the + 1 from the substr().
One might guess that you're using an Ubuntu Linux distribution from your command prompt, but you haven't given us any indication of what shell you're using. Although written and tested using a Korn shell, the above should work with any POSIX-conforming shell. If you're using a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.
does anyone know how to combine 2 lines? this is what im playing around with.

I'm using korn shell to connect to oracle, retrieve certain values, put them in a list, and iterate through them. While this method works, I can't help but think there is an easier method.
If you know of one, please suggest a shorter, more efficient method.

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
