Search and Replace in a new FILE.
Hi,

more data.txt
Quote:
white=black
red=green
blue=pink
more srstring.sh
Code:
input="data.txt"
while IFS= read -r var
do
startdirectory=$loc
search=$(echo $var | awk -F'=' '{print $1}')
replace=$(echo $var | awk -F'=' '{print $2}')
find "/tmp/config" -type f -exec grep -l "$search" {} + |
while read file
do if sed -e "s#$search#$replace#g" "$file" > /tmp/tmpfile.tmp
then mv /tmp/tmpfile.tmp "$file"
echo $file
printf "Modified: %s\n" "$file"
fi
done
rm -f /tmp/tmpfile.tmp
done < "$input"

srstring.sh reads data.txt line by line and replaces right side value with the left in any file found under /tmp/config folder.

So.
Quote:
more /tmp/config/myfolder/hello.txt BEFORE running the srstring.sh

I saw the following colors in the book viz white, red and blue
Quote:
more /tmp/config/myfolder/hello.txt AFTER running the srstring.sh

Now, my requirement is rather than replacing & saving the values in the the same file i would like to have the original files untouched .. rather save the replace file as <original-filename>_tmp.replace

So, after running the srstring.sh

Can you let me know how can i easily tweak my code to achieve the same ? Also, it will be great if it runs on Linux as well as Solaris.

ppmtopgm

ppmtopgm(1)						      General Commands Manual						       ppmtopgm(1)

NAME

       ppmtopgm - convert a portable pixmap into a portable graymap

SYNOPSIS

       ppmtopgm [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as  input.  Produces a portable graymap as output.  The output is a "black and white" rendering of the original
       image, as in a black and white photograph.  The quantization formula used is .299 r + .587 g + .114 b.

       Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any  ppm  program  can
       read  pgm  (and	pbm  ) files automatically.  pgmtoppm is for colorizing a pgm file.  Also, see ppmtorgb3 for a different way of converting
       color to gray.  And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate  the  original
       colors, not necessarily a way that looks like a black and white photograph.

QUOTE

       Cold-hearted orb that rules the night
       Removes the colors from our sight
       Red is gray, and yellow white
       But we decide which is right
       And which is a quantization error.
