Hello Scrutinizer,

Thanks, it works that way.

The pat2 could be in more than line, so to could use your code, intead of have 32 elements in a line I changed it to 64 with xxd command, and without spaces.

So, your first code continue working, but I don't know why is not printing all patterns even they are in the file, I got this output:
$ awk -v pat="ff44.{6,18}321456.{5}" '
  {    b=p $0  }
  match(b,pat) {    print substr(b,RSTART,RLENGTH); sub(pat,x)
  {    p=$0 FS  }' file2.txt

But the correct output should be (the patterns that have the sequence 01 and 05 are not being printed):

The input file is:

Thanks in advance for the help.

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
