Replace values in a file with values from another file
Hi,

I have 2 input files:

File 1:

Code:
echo Name > create_Name.txt 
echo Group /dir/group, Name >> create_Name.txt

File 2:

Code:
Name AAA BBB CCC
group A B C
dir A1 B1 C1

................................

Need to replace the contents of File 1 with column 2, 3 & 4 values of File 2 where ever column 1 of File 2 matches with the words in File 1. The number of output files would be number of columns in File 2 minus 1. In this case it would be 3.

ie., Contents of Output File1 (cre_AAA.sh) would be:

Code:
echo AAA > create_AAA.txt
echo Group /A1/A, AAA >> create_AAA.txt

Contents of Output File2 (cre_BBB.sh) would be:

Code:
echo BBB > create_BBB.txt
echo Group /B1/B, BBB >> create_BBB.txt

Contents of Output File3 (cre_CCC.sh) would be:

Code:
echo CCC > create_CCC.txt
echo Group /C1/C, CCC >> create_CCC.txt

and so on ...

File 1 is static but File 2 would be dynamic. There could be many columns (AAA, BBB,...FFF) and parameters (Name, dir, group, ... location) in it.

Can someone please help me with this?

Thanx

-Gc

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.
