I took this a little over-the-top, but it was a fun excersize. Here's
my adaptations to set_prompt():
set_prompt ()
{
local EUID=$1;
local NORMAL=`tput sgr0 2> /dev/null`;
local BOLD=`tput bold 2> /dev/null`;
# local DIM=`tput dim 2> /dev/null`;
local BLINK=`tput blink 2> /dev/null`;
# local REVERSE=`tput rev 2> /dev/null`;
# local STANDOUT=`tput smso 2> /dev/null`;
# local UNDERLINE=`tput smul 2> /dev/null`;
# local INVISIBLE=`tput invis 2> /dev/null`;
# local BEEP=`tput bel 2> /dev/null`;
# local HOME=`tput home 2> /dev/null`;
# local CLEAR=`tput clear 2> /dev/null`;
# local FG_BLACK=`tput setaf 0 2> /dev/null`;
local FG_RED=`tput setaf 1 2> /dev/null`;
# local FG_GREEN=`tput setaf 2 2> /dev/null`;
local FG_YELLOW=`tput setaf 3 2> /dev/null`;
# local FG_BLUE=`tput setaf 4 2> /dev/null`;
# local FG_MAGENTA=`tput setaf 5 2> /dev/null`;
local FG_CYAN=`tput setaf 6 2> /dev/null`;
local FG_WHITE=`tput setaf 7 2> /dev/null`;
# local BG_BLACK=`tput setab 0 2> /dev/null`;
# local BG_RED=`tput setab 1 2> /dev/null`;
# local BG_GREEN=`tput setab 2 2> /dev/null`;
# local BG_YELLOW=`tput setab 3 2> /dev/null`;
# local BG_BLUE=`tput setab 4 2> /dev/null`;
# local BG_MAGENTA=`tput setab 5 2> /dev/null`;
# local BG_CYAN=`tput setab 6 2> /dev/null`;
# local BG_WHITE=`tput setab 7 2> /dev/null`;
if [ "$EUID" == "0" ]; then
PS1="\[${NORMAL}${BOLD}${BLINK}${FG_RED}\]\u\[${NORMAL}${BOLD} \
[EMAIL PROTECTED]: ";
else
PS1="[EMAIL PROTECTED]
${FG_CYAN}\]\h\[${NORMAL}\]: ";
fi;
PS2="\[${NORMAL}${BOLD}${FG_YELLOW}\]continue\[${NORMAL}\]> ";
return
}
set_prompt $EUID
For root the username is in blinking, bright red - to help remind you of
your login. For Regular Users the username is bright yellow. From there
it's a bright white '@' and then the hostname in bright cyan. Oh, yeah, I
almost forgot the ": " in bright white at the end. [Too much time waiting
for downloads...]
Use it if you want.
Chuck
PS. Don't forget to put the set_prompt() function somewhere where it
will get executed for those times you `su` or `su -`.
