Hello!
I read in the Configuration HOWTO that RedHat & Slackware Linux can use
Escape control codes to add color support (and some default settings;
like LESS as a default pager) to the prompt line, see below:
_____
# /etc/profile
# System wide environment and startup programs
# Functions and aliases go in /etc/bashrc
# This file sets up the following features:
#
# o path
# o prompts
# o a few environment variables
# o colour ls
# o less
#
# Users can override these settings and/or add others in their
# $HOME/.bash_profile
# set a decent path
echo $PATH | grep X11R6 > /dev/null
if [ $? = 1 ] ; then # add entries to the path
PATH="$PATH:/usr/X11R6/bin:$HOME/bin:."
fi
# notify the user: login or non-login shell. If login, the prompt is
# coloured in blue; otherwise in magenta. Root's prompt is red.
USER=`whoami`
if [ $LOGNAME = $USER ] ; then
COLOUR=44
else
COLOUR=45
fi
if [ $USER = 'root' ] ; then
COLOUR=41
fi
# put a real escape character instead of ^[. To do this:
# emacs: ^Q ESC vi: ^V ESC joe: ` 0 2 7 jed: ` ESC
# Remove `;1' if you don't like the `bold' attribute.
ESC=^[
PS1='$ESC[$COLOUR;37;1m$USER:$ESC[37;40;1m\w\$ '
PS2="Continue> "
# no core dumps, please
ulimit -c 0
# set umask
if [ `id -gn` = `id -un` -a `id -u` -gt 14 ]; then
umask 002
else
umask 022
fi
# a few variables
USER=`id -un`
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
EDITOR=jed
HOSTNAME=`/bin/hostname`
HISTSIZE=1000
HISTFILESIZE=1000
export PATH PS1 PS2 USER LOGNAME MAIL EDITOR HOSTNAME HISTSIZE
HISTFILESIZE
# enable colour ls
eval `dircolors /etc/DIR_COLORS -b`
export LS_OPTIONS='-F -s -T 0 --color=tty'
# customise less
LESS='-M-Q'
LESSEDIT="%E ?lt+%lt. %f"
LESSOPEN="| lesspipe.sh %s"
VISUAL=jed
LESSCHARSET=latin1
export LESS LESSEDIT LESSOPEN VISUAL LESSCHARSET
for i in /etc/profile.d/*.sh ; do
if [ -x $i ]; then
. $i
fi
done
___
The important part is:
# notify the user: login or non-login shell. If login, the prompt is
# coloured in blue; otherwise in magenta. Root's prompt is red.
USER=`whoami`
if [ $LOGNAME = $USER ] ; then
COLOUR=44
else
COLOUR=45
fi
if [ $USER = 'root' ] ; then
COLOUR=41
fi
# put a real escape character instead of ^[. To do this:
# emacs: ^Q ESC vi: ^V ESC joe: ` 0 2 7 jed: ` ESC
# Remove `;1' if you don't like the `bold' attribute.
ESC=^[
PS1='$ESC[$COLOUR;37;1m$USER:$ESC[37;40;1m\w\$ '
PS2="Continue> "
I tried to make this work, so the prompt is in color, but instead it
outputs the PS1= line almost verbatim for a prompt. Can this work in
debian? Do I need to change something?
Thanks for any feedback
Dave Jones
