When you bpsh to a slave node, it will automatically put you in the
same directory on the slave node that you are in on the master node. If
you're in a directory that doesn't exist on the slave node, it will just
change your directory to be / on the slave node.
If you're trying to just do ls, you can also try telling ls which
directory to looks at, ie:
bpsh 0 ls -l /usr
