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

ssh-argv0

SSH-ARGV0(1)						    BSD General Commands Manual 					      SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.	If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES
