accidentally deleted /usr/bin can't chroot back

my typos finally caught up with me what was meant to be a forward slash turned to a space and now I am stuck on live enviroment with no idea what to do

mount /dev/nvme0n1p3.    (ext4)
arch-chroot /mnt

failed to run command "/bin/bash" no such file or directory

bash really doesn't exist on the system anymore
any help is appreciated

You're not posting the actual output…

Also the command there will NOT re-install all packages… bbs botched the link a bit but that's not an excuse to do random stuff.

Re: accidentally deleted /usr/bin can't chroot back

I am unable to post actual output because I don't have an available computer to ssh into the live install I am writing this on my phone

with these flags and arguments it seems to go Much further but alas still fails

> pacman -S --sysroot /mnt $(pacman -Qnq)

Re: accidentally deleted /usr/bin can't chroot back

"foobar 2>&1 | tee /tmp/whatamidoing.txt", then see the 1st link below.

Did you

See Chroot#Using chroot on how to mount the necessary filesystems required by --sysroot.

(pacman --sysroot might still fail because of the lost /bin on the chroot in which case you'll have to use --root)

Sanity check (just occurred to me that you've probably not checked that)

stat /mnt/usr/bin/bash

Re: accidentally deleted /usr/bin can't chroot back

Have you tried just doing another pacstrap  to install the core system again?
