thank you
Its really working awesome.But my question is my original file1.txt and file2.txt have records in millions,so does it take huge time or efficient enough.
---------- Post updated at 11:21 PM ---------- Previous update was at 11:12 PM ----------
i need to compare the same for filed3 also.Iam java developer so no idea about shell script please help me regarding this also.I mean to say if filed3 filed2 changes i need to show both changes.
File1.txt
'393200103088';'TIM';'20060207'
File2.txt
'393200103088';'TIM';'20060208'
common.txt(Filed3 has changed for filed1)
'393200103088' '20060201' '2006208'
---------- Post updated at 11:39 PM ---------- Previous update was at 11:21 PM ----------
I had generated file3.txt by the following command.
diff file1.txt file2.txt > file3.txt
If you look into file3.txt
The records missing from file2 started with < symbol.
And the records missing from file1 started with > symbol.
And it also has coommon records(coomon first field)using this i have to generate same three files as i have mentioned in previous thread.
1.misssed_file1.txt
2.missed_file2.txt
3.common.txt
< '393200103052';'H3G';'20081204'
< '393200103059';'TIM';'20110111'
< '393200103061';'TIM';'20060206'
< '393200103064';'OPI';'20110623'
> '393200103052';'HKG';'20081204'
> '393200103056';'TIM';'20110111'
> '393200103088';'TIM';'20060206'
I think here > and < symobls are helpful to generate required files.
please help me regarding this.

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.
