Hammer & Screwdriver What is currently working

Thanks for your suggestion, what I am looking for now is to loop through the list.

I have just modified the code to:
Code:
cat $filename2 | sed '/Email/d;/Web/d' > temp.1

Code:
mv temp.1 $filename2

This works for one file.

I was looking for a way to handle errors (what if it runs and has no files?)
and what if more than one files comes in?

As mentioned, I can create a file that has the list.

Hi,

I tried the FILE code with multiple files

the message I got back was;
/bin/fix2.sh[3]: FILE: not found and it keep the editor open needed to ctrl 'c' to get prompt back.

Is the code you suggested exactly what I should type? or is FILE something I needed to change?

I am very new to this scripting.

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. SEE ALSO
