ESC=$(printf '\33') export MANCOLORS="LESS_TERMCAP_md=$ESC[31m LESS_TERMCAP_me=$ESC[0m" export MANPAGER='sh -c "eval $MANCOLORS less"' man ls git help git At least on Linux, $MANPAGER is some weird limbo that is not run with the shell, but not just a simple command. Hence the extra layer of "sh". If I were actually planning to use this myself, I'd probably put it in a "manpager" script in my $PATH and just do MANPAGER=manpager. -Peff
