I always use color, as you. The statement that prompt is more
important than command output is just plain wrong. I use the same color
as you (green for me and red for root), plus other fancy colours for
other system usernames (eg www-data). It is very important also to
remind you when you are in a chroot. Here is my prompt for root (note
the color list in the comment):
----------------------------
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
fi
# set a fancy prompt (non-color, unless we know we "want" color)
# \[\033[01;XXm\] changes the color
# with XX= 30->black-bold, 31->red, 32->green, 33->yellow, 34->blue,
35->cyan
# and \[\033[00m\] to return to the default color
case "$TERM" in
xterm*)
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$
'
;;
*)
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
;;
esac
----------------------------
Cheers.
