So if your file has several fields that you can create an expression for, then that should do it.
If the separator is , then an ignored field is .*, meaning zero or more (*) of any character (.) followed by the field separator (,)
So, to count from the beginnig of the line your expression starts as ^.*,.*, to signify start of record (^) the ignore two fields. You can then tag on 1,1,1, to specify your requirements and the rest doesn't matter if it matches or not.
I think you can end up with:-
Code:
egrep "^.*,.*,1,1,1," input_file
From your sample input, I get one less line because the one starting jkhu does not have the correct field separator between fields 2 & 3.
Is there a way to grep for something and then print out 10 lines after it.
for example if I want to grep for a word, then output the following 10 or whatever number of lines after the word. (5 Replies)
Using shell scripts, I use grep to find the word “error” in a log file:
grep error this.log.
How can I print or get the line 3 lines below the line that word “error” is located?
Thanks in advance for your response. (9 Replies)

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.
