"The Bash-Prompt HOWTO" @ tldp.org
is a good one. Just to give you an idea about how crazy this all can
get, take a look at this prompt (for zsh). Note that ^[ means the
real ESC character, not caret + left bracket. Sorry about the long lines:
PS1='%{^[[1;34m%}--[ %{^[[1;36m%}$(pwd), $(ls -1 | wc -l | tr -d " ") files / ${SIZE}%{^[[1;34m%} ]-- --[ %{^[[1;36m%}$(date "+%I:%M %p")%{^[[1;34m%} ]-- --[ %{^[[1;36m%}%n @ %M[$(jobs | wc -l | tr -d " ")] / $(tty | sed "s:/dev/pts/:ttyp:g;s:/dev/::g")%{^[[1;34m%} ]--
--[ %{^[[1;36m%}$(ps ax | wc -l | tr -d " ") processes%{^[[1;34m%} ]-- --[ %{^[[1;36m%}$(who | wc -l | tr -d " ") users%{^[[1;34m%} ]--
--[ %{^[[1;36m%}%# %{^[[1;34m%}]-- %{^[[0m%}'
PS2='%{^[[1;34m%}--[ %{^[[1;36m%}%_ > %{^[[1;34m%}]-- %{^[[0m%}'
function precmd () {
let TotalBytes=0
for Bytes in $(command ls -l | grep "^-" | awk '{ print $5 }')
do
let TotalBytes=$TotalBytes+$Bytes
done
if [ $TotalBytes -lt 1024 ]; then
TotalSize=$(echo -e "scale=0 \n$TotalBytes \nquit" | bc | tr -d '\n')
suffix=" bytes"
elif [ $TotalBytes -lt 1048576 ]; then
TotalSize=$(echo -e "scale=0 \n$TotalBytes/1024 \nquit" | bc | tr -d '\n')
suffix="K"
elif [ $TotalBytes -lt 1073741824 ]; then
TotalSize=$(echo -e "scale=0 \n$TotalBytes/1048576 \nquit" | bc | tr -d '\n')
suffix="M"
else
TotalSize=$(echo -e "scale=0 \n$TotalBytes/1073741824 \nquit" | bc | tr -d '\n')
suffix="G"
fi
SIZE="${TotalSize}${suffix}"
UPTIME="`uptime | sed -e 's/.* \(.* days,\)\? \(.*:..,\) .*/\1 \2/' \
-e 's/,//g' -e 's/ up //'`"
}
It makes a prompt like this, but in color:
--[ /, 33 files / 10M ]-- --[ 10:23 AM ]-- --[ oremanj @ webserver.get-linux.org[0] / ttyv1 ]--
--[ 136 processes ]-- --[ 4 users ]--
--[ % ]-- <command-goes-here>
-- Josh
P.S. Of course I don't use that prompt!
