BASH and/or .BASHRC not working properly after SU or SSH login unless run “bash” command

Question

I have an Amazon EC2 Machine running Ubuntu 10.04.

The default user, ubuntu's .bashrc seems to be behaving properly, but if I ssh or su to the second user, Kunsan, it doesn't display properly until I run bash:

Ex 1.) Changing user with su

kunsan@home ~$ ssh ubuntu@EC2

ubuntu@EC2:~$

ubuntu@EC2:~$ su kunsan

$ 

$ bash

kunsan@EC2: $

Ex 2.) SSH-ing indirectly as the user

kunsan@home ~$ ssh mikey@EC2

/home/kunsan/.bashrc: 13: shopt: not found

/home/kunsan/.bashrc: 21: shopt: not found

/home/kunsan/.bashrc: 99: shopt: not found

/etc/bash_completion: 33: [[: not found

/etc/bash_completion: 39: [[: not found

/etc/bash_completion: 52: Bad substitution

\[\e]0;\u@\h: \w\a\]\u@\h:\w$

\[\e]0;\u@\h: \w\a\]\u@\h:\w$ bash

kunsan@EC2:~$

I've tried playing around with ~/.profile and ~/.bash_login to include

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

Fi

but so far, nothing has seemed to do the trick.

You can try to change it with this command, where /bin/bash is the location of bash

usermod -s /bin/bash kunsan
