i.e. Jochen needs to find a way to get e.g. echo to actually print an ESC
where it is apropriate. NOTE, for bash:
$ /bin/echo -e "\033[36;7m Reversed colors \033[m Standard colors"
Reversed colors Standard colors
$ type -a echo
echo is a shell builtin
echo is /usr/bin/echo
echo is /bin/echo
$ echo -e "\e[36;7m Reversed colors \e[m Standard colors"
Reversed colors Standard colors

Help for checking; $ man od
e.g: $ echo TEST | od -t x1z
Example of color code use from bash/rxvt:
$ echo -e "\e[7m Reversed colors \e[m Standard colors"
-- fgtab --
#!/bin/bash
echo "Foreground/Background table"
for (( f=0; f<8 ; f++ ));do
for (( b=0; b<8 ; b++ ));do
echo -en "\e[3${f};4${b}m $f/$b \e[m";
done;
echo -e "\e[m";
done
-- eof --
I'm not sure this works in anything else than a rxvt and cmd/command
*window* (ANSI.SYS activates the same for old "DOS").
I believe the codes are for some sort of ANSI terminal (I learnt them on the
Amiga
where they work in the Shell/CON window and at least in part for the
printer).
