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

shar

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME

     shar -- create a shell archive of files

SYNOPSIS

     shar file ...

DESCRIPTION

     shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands.
     Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).

     shar is normally used for distributing files by ftp(1) or mail(1).

EXAMPLES

     To create a shell archive of the program ls(1) and mail it to Rick:

	   cd ls
	   shar `find . -print` |  mail -s "ls source" rick

     To recreate the program directory:

	   mkdir ls
	   cd ls
	   ...
	   <delete header lines and examine mailed archive>
	   ...
	   sh archive

SEE ALSO

     compress(1), mail(1), tar(1), uuencode(1)

HISTORY

     The shar command appeared in 4.4BSD.

BUGS

     shar makes no provisions for special types of files or files containing magic characters.

SECURITY CONSIDERATIONS

     It is easy to insert trojan horses into shar files.  It is strongly recommended that all shell archive files be examined before running them
     through sh(1).  Archives produced using this implementation of shar may be easily examined with the command:

	   egrep -v '^[X#]' shar.file
