How to change bash prompt for arch32 bundled system.

I recommend that you use a custom bash prompt inside your 32bit chroot installation to know where you are (i.e. inside the 32bit chroot). You can, for example, add a ARCH32 string to your PS1 string that you may have defined in .bashrc or other config file.

Taken from:
http://wiki.archlinux.org/index.php/Arc … bit_system

But no explanation for n00bs like me on how to do that!!

Do I have to edit the .bashrc in the home folder under /opt/arch32/ ? (can I do that from normal root, or do I have to be chrooted?)

And what exactly should the .bashrc look like to give me a reploid@archcomputer-inside32 prompt?

#PS1='[\u@\h \W]\$ '

What has to be edited here in order to give me a separate bash when chrooting into arch32?

Can anybody help me out here before I break my system..?

Add "-inside32" after "h" in that PS1 in /opt/arch32/.bashrc, shouldn't matter whether you make it before running "chroot" or after.

Re: How to change bash prompt for arch32 bundled system.

Thank you, I can change the name of the bashprompt now.

Problem is that it doesn't seem like it is applied to only the prompt I get when chrooting to arch32. It seems like by editing .bashrc in /opt/arch32/home/reploid, the file is universally changed. Very strange.

Am I still logged in as root in other terminals after having chrooted into arch32 in one of them? How do I get out of chroot and into my normal 64 system to see if bash looks different there?

Your /opt/arch32 chroot shares the same /home/user dir, You need to change the prompt in the opt/arch32/root/.bashrc file.

mine looks like this...

PS1='\[\e[1;35m\]arch32 ch\u\[\e[m\] \[\e[1;36m\]\w\[\e[m\] \[\e[1;32m\]> \[\e[m\]\[\e[0;37m\]'
PS2='>'

my normal prompt in  /home/user/.bashrc  and in  /root/.bashrc looks like this...

PS1='\[\e[1;35m\]\u\[\e[m\] \[\e[1;36m\]\w\[\e[m\] \[\e[1;32m\]> \[\e[m\]\[\e[0;37m\]'
PS2='>'

to exit the chroot, at the prompt just type exit
