Just provisioned a new Rackspace instance with Ubuntu 12.04 and pulled down rbenv from their github and installed it.

I'm getting the following errors when executing . ./~bashrc

$ . ~/.bashrc
sh: 18: /home/deployer/.bashrc: shopt: not found
sh: 26: /home/deployer/.bashrc: shopt: not found
sh: 110: /home/deployer/.bashrc: shopt: not found
sh: 28: /etc/bash_completion: [[: not found
sh: 34: /etc/bash_completion: [[: not found

Here is my .bashrc (for user deployer), the only thing I added was the rbenv bit at the top.

$ cat .bashrc

case "$TERM" in

    # We have color support; assume it's compliant with Ecma-48

    # a case would tend to support setf rather than setaf.)

if [ "$color_prompt" = yes ]; then

    Are you actually running bash as your shell? – womble Jul 22 '12 at 5:14
  • Agree with @womble. Even the error messages say sh. What does cat /proc/$$/cmdline show? – glenn jackman Jul 22 '12 at 5:35
  • 1
    Or even echo $SHELL... – womble Jul 22 '12 at 5:36
  • I find that's not always accurate (may depend on one's rc files). From bash, try /bin/sh -c 'echo $SHELL' -- for me that returns "/bin/bash" even though my /bin/sh is a symlink to dash. – glenn jackman Jul 22 '12 at 5:41
  • @glennjackman I added the results of those commands in the question. All seem to point sh. How can I get bash? – Chris Jul 23 '12 at 2:45

The output you just posted indicates that you aren't actually running bash. This is why you are getting errors sourcing .bashrc.

To fix this problem, you need to check your login shell to make sure it's actually set to bash:

chsh -l

will list the available shells, and

chsh -s /path/to/bash

will change your login shell to bash.

Then logout and log back in.

    chsh -l gives chsh: invalid option -- 'l' – Chris Jul 23 '12 at 3:15
  • well I checked on root for the path (/bin/bash) and it's all good now. Thanks for the help! – Chris Jul 23 '12 at 3:16

shopt is a bash builtin, not a standalone executable, so source won't work. That's why you're getting that error. What are you trying to accomplish?

  • I didn't write that part. I just need to add the first couple of executable lines about RBENV so that it can run in non-interactive mode (since the [ -z "$PS1" ] && return) will stop that from happening – Chris Jul 22 '12 at 4:02
  • Also by source I am doing . ~/.bashrc, will fix in question – Chris Jul 22 '12 at 4:02

This problem occurs when you source your bashrc file from other shells (like zsh). Make sure this line is not present in your current shell's rc file

source ~/.bashrc

To check current shell, execute:

echo $SHELL

    there is in my opinion no new information posted in this answer, which wasn't already in other answers, to a 6 year old question. – Dennis Nolte May 3 '18 at 11:13
