while using chroot - want custom prompt

dalingrin · 2009-03-18 04:03:41

I just created a 32bit chroot which is working great but, I want an easy way to tell if I am using 64bit or 32bit root at the console.
I had the great idea of using .bashrc but then I realized I would need to script a way to differentiate between 32 and 64 bit. My first thought was uname -m but stupid me, didn't think about the fact that I am still using the same kernel so that won't work.
Any help is appreciated.

btw, first post as an Arch user, yay!

[Edit] - wait...just realized since it lists the user(root), that is probably enough for me to know the difference.
Looks like my first post is for not.

Hi,

use this command when you enter to 32 bit chroot:

linux32 chroot /path/to/chroot

So all programs see that are in 32 bit env

Good Luck!

This is what I use for bash. Make a file inside the root of your 32-bit chroot called inside-choot.
Then you add the following to your .bashrc:

if [[ -f /inside-chroot ]]; then
PS1='\[\e[1;35m\]arch32 ch \u\[\e[m\] \[\e[1;36m\]\w\[\e[m\] \[\e[1;32m\]> \[\e[m\]\[\e[0;37m\]'
fi

Change the PS1 line to whatever you like, I think i found this from another thread in this forum. Anyway good luck:)

Thanks, I was wondering why applications were reporting x86_64
