If I am reading your post correctly then you are looking for the attributes to a string/character at any random part of an echo to a terminal.
This can't be done so you have no choice but to do it manually.
The terminal emulator has no concept of BIOS interrupt (0x)10, subcommand (0x)08, IIRC, so you will have to hard code each line of your listing yourself.

I am not sure how much easier it would be to hard code each complete line listing in the corresponding colour(s) but could be an alternative to look at something like this...

Thanks wisecracker for your reply,the actual requirement in our project is that we have a java program that prints text to the terminal when manually run and red when printed in all instances is an error,our requirement is that we need to send an email whenever red is outputted.
Now this check is being done manually we are planning to convert to cron tab and divert this output to a file and mail in cases only when file has anything in red color.But the problem here is when I redirect I am lossing the colors

---------- Post updated at 08:12 PM ---------- Previous update was at 08:10 PM ----------

In short the question is how do the retain color when text is redirected to a file.

ls -l --color|less -R would retain color

but how to I retain color when

someunixcommandwhich prints colored text>filename

You can add other conditions and use below
Code:
ls -l | awk '{if($1 ~ /^d/) {$9 = ("<FONT COLOR=\"GREEN\">" $9 "</FONT>")}
  else if($1 ~ /^l/) {$9 = ("<FONT COLOR=\"BLUE\">" $9 "</FONT>")}
  else if($1 ~ /x/) {$9 = ("<FONT COLOR=\"PURPLE\">" $9 "</FONT>")}
  else if($9 ~ /.gz$/ || $9 ~ /.Z$/) {$9 = ("<FONT COLOR=\"RED\">" $9 "</FONT>")}
  else {$9 = ("<FONT COLOR=\"WHITE\">" $9 "</FONT>")}; print}'

or use below and save the output to sample.html and open the html file to see colors

Code:
ls -l | awk '{if($1 ~ /^d/) {$9 = ("<FONT COLOR=\"BLUE\">" $9 "</FONT>")}
  else if($1 ~ /^l/) {$9 = ("<FONT COLOR=\"PURPLE\">" $9 "</FONT>")}
  else if($1 ~ /x/) {$9 = ("<FONT COLOR=\"GREEN\">" $9 "</FONT>")}
  else if($9 ~ /.gz$/ || $9 ~ /.Z$/) {$9 = ("<FONT COLOR=\"RED\">" $9 "</FONT>")}
  else {$9 = ("<FONT COLOR=\"BLACK\">" $9 "</FONT>")}; print $0 "<BR>"}' > sample.html

I can recommend pixelbeat's ansi2html.sh

Code:
ls -rlt --color | ansi2html.sh > king.html

Thanks mate for your reply,however the shell script I am executing does not have --color option,its a custom script written which is printing colors using awk and echo

Since ls has --color options that works fine but what if a custom script does not have color option,Thanks

Code:
ls -rlt --color | ansi2html.sh > king.html

Well using ls was just an example, the reason --color is needed for the ls command is that it normally detects that the output isn't a terminal and avoids outputting any color escape sequences. This is probably to simplify scripts that process the ls output.

Now unless your custom script has a similar feature i.e checking stdout and only outputting plain text when it's not a terminal this should all be fine.

Checking this script ansi2html.sh script it does require python, however it should be a pretty trivial exercise to change it to use awk instead.

Edit: Re-reading your posts I'm guessing your script does check the output type and only print the color escape sequences if the output is a terminal. It's probably checking [-t 1] or something similar. I've encountered this issue before myself and found using ssh is a nice workaround.

Say your script is called output_color then you could call it like this:

Code:
$ ssh -t localhost /usr/local/bin/output_color | ansi2html.sh > king.html

or using ls and an example:

Code:
$ ssh -t localhost "cd $PWD; ls" | ansi2html.sh > king.html
