Hi guys,
I got a good one!
I colorized my prompt as follow; Green for normal user, Red for root:
Root .bashrc:
PS1=”\e[0;31m[\t][\u@\h:\w][\!]\\$ \e[m"
User .bashrc:
PS1="\e[0;37m[\t][\u@\h:\w][\!]\\$ \e[m"
Which gives:
[17:53:18][root@T42:/home/netweezurd][93]#
in technicolor…
When the command I’m typing is longer than the screen, the cursor returns to the left margin but not to a new line anymore, if I continue typing it kind of overwrite the prompt on the same line. If I backup it does jump one line up and ends up on the line of the previous command… in emptiness… unworkable !
Right now I’m putting nix on a usbkey and it’s giving me:
[17:53:18][root@T42:/home/netweezurd][93]# ^C
[17:53:18][root@T42:/home/netweezurd][93]# livecd-iso-to-disk –overlay-size-mb 512 –format –reset-mbr Fedora-13-i686-Live-Security/Fedora-13-i686-Live-Security.iso /dev/sdb1weezurd][93]#
I dunno if you can figure it, the weezurd part at the end is on the same line, the cursor just wrapped around.
My normal no color prompt does not do that.
PS1=”[\t][\u@\h:\w][\!]\\$ ”

Any clues ???
I got it to work… with some help from penguiniator & David the H. over at linuxquestions.org.
I think your missing escape sequences:
This work ok: PS1=”\[\e[0;31m\][\t][\u@\h:\w][\!]\\$ \[\e[m\]”
Compared to: PS1=”\e[0;31m[\t][\u@\h:\w][\!]\\$ \e[m”
