Dear Hans-Bernhard:

Many thanks for the hint with the -r command! This does work perfectly
under Linux. I can even issue the command 
ls --color=yes -l | less -r 
and get the colors.

However, in DJGPP bash the -r command changes the ESC into a single
character (little arrow pointing left), i.e. the output looks like
 <-[00m_bashrc<-[00m
where the <- is just one character.

I wonder whether this is a non implemented feature in DJGPP bash, or a
misconfiguration of some kind on my side.

Any advice?

Thanks a lot,


Wolfgang
