sudo chmod 700 /bin && sudo chmod 700 /bin

sudo chmod 700 /bin && sudo chmod 700 /bin

would only change the permissions on the /bin directory itself, or if it’s a symlink, the directory it points to. This would make the contents of the directory inaccessible to non-root users, but the damage is limited.

You can recover by logging in as root, or booting into a rescue environment (both of these require knowing the root password), or booting from a rescue device, and then running

chmod 755 /bin

You don’t need to re-install.
