getting stderr & stdout output lively modified
This is about getting all output to stderr and stdout localized. Nothing to do with redirecting output to a file (there already are some interesting threads about that issue on this forum).

What I intend to do is capturing all lines of text sent to the screen, compare them with an array of stored lines and replace the matching ones in the screen for their translated equivalents.

I'm aware of TEXTDOMAIN and alike, but unfortunately many scripts are not prepared for localization, so I want to try a different approach, tryng to translate everything carelessly if the script uses $"" or not for calling gettext.

I have been trying 2 ways:

1: Getting many commands that generate writen output intercepted. After editing etc/profile, ~/bashrc, setting aliases, expand_aliases and lots of things, I can get them catched only in interactive mode, but when running a script, no alias at all is keept (nor other settings). F.i., if I type "enable" in the shell, I see that echo has dissapeared (I replace it for my own). But running a script that contents the same command, echo is enabled again!. Should not expand_aliases have avoided this?

2: Some kind of daemon that could replace the standard output and give back the translated messages (or the original ones if not matched). Even it could be enough to append the translated lines to the already shown in english. I guess that I would have to redirect /dev/fd/? , /dev/tty? or something like that but i lack the knowledge to do it, if it can be done. Some tries done with no succes.

Could anybody point a solution, advise, whatever could help?

Thank you in advance.

gettext

GETTEXT(1)								GNU								GETTEXT(1)

NAME

       gettext - translate message

SYNOPSIS

       gettext [OPTION] [[TEXTDOMAIN] MSGID]
       gettext [OPTION] -s [MSGID]...

DESCRIPTION

       The gettext program translates a natural language message into the user's language, by looking up the translation in a message catalog.

       Display native language translation of a textual message.

       -d, --domain=TEXTDOMAIN
	      retrieve translated messages from TEXTDOMAIN

       -e     enable expansion of some escape sequences

       -E     (ignored for compatibility)

       -h, --help
	      display this help and exit

       -n     suppress trailing newline

       -V, --version
	      display version information and exit

       [TEXTDOMAIN] MSGID
	      retrieve translated message corresponding to MSGID from TEXTDOMAIN

       If the TEXTDOMAIN parameter is not given, the domain is determined from the environment variable TEXTDOMAIN.  If the message catalog is not
       found in the regular directory, another location can be specified with the environment variable	TEXTDOMAINDIR.	 When  used  with  the	-s
       option  the program behaves like the 'echo' command.  But it does not simply copy its arguments to stdout.  Instead those messages found in
       the selected catalog are translated.  Standard search directory: /usr/share/locale
