I think I managed to break my Snow Leopard shell, but I'm not sure. Is there a way to reset all env variables to default?

  • I was trying to install Sphinx4 from src. I changed a whole bunch of env variables to use the specific java library, but in the process made some bad changes so now no java program runs.

Reset to default

Close terminal and re-open a new one. Any environments variables you set in the last session will be gone.

If the problem persists, you probably edited ~/.bashrc or ~/.bash_profile; edit them again and remove any changes (or if you want to get right back to the default OS X state, just remove them completely - a default OS X install has these files empty or non-existent).

One of the following:

  • Exit the shell and start it again.
  • Log out and log in.
  • . /etc/bash.bashrc
  • . ~/.bashrc
  • exec bash -i

The two that start with "dot" source your startup files which will reset some of your environment variables (but may make your $PATH variable longer - probably with no consequences).

  • Isn't it ~/.bashrc, not ./bashrc?
