I am trying to remove whitespaces from a file containing sample data as:
. Basically these files are delimited extracted files from a database with the delimiters as <EOFD>
I am using the below command to remove the whitespace perl -pi -e 's/[[:space:]]*\<EOFD\>[[:space:]]*/\<EOFD\>/g' sample.dat
The above command is part of shell scripts t.ksh which is being invoked on the command line and internally runs the perl command.
It is working fine for moderately huge files but once the file reaches a conderable huge size, say 2.2 -3 GB, it empties the file content and the scripts exist with the below error:
./t.ksh[249]: 700492 Memory fault(coredump)
Server Message: <my unix machine name>- Msg 208, Level 16, State 1:
[249] - this points to my perl command. Also, I see a huge coredump file getting created in the directory from where I am invoking the shell script t.ksh. The file system has adequate space.
Can someone advise whats wrong here or any workaround?
Regards

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.
