awk: too many output files 10
 record number 610

Hi - thanks for responding quickly

Tried that but same error. It creates output files from 0 to 9 with some output but fails with error above.

Any ideas?

Hi - Found some error - as I was using solaris version of awk - so now using the POSIX awk


This works
Code:
$ /usr/xpg4/bin/awk '/CP START/{close(x);x="F"++i;}{print > x;}' inputfile

however this fails:
Code:
$ /usr/xpg4/bin/awk '/CP START ACCOUNT/{close(x);x="F"++i;}{print > x;}' inputfile 
/usr/xpg4/bin/awk: line 0 (NR=1): output file "": No such file or directory


How can I get the above to succeed
Also - can I get the split to only split the file after say 20 matches of "CP START ACCOUNT" ?

ppmtosixel

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.
