I installed Ubuntu in Virtualbox in a MacBook Pro laptop. In ~/.bash_profile, I added some directories to PATH. But after I reboot the guest Ubuntu, the added directories are not in PATH. I wonder why ~/.bash_profile isn't executed after the guest Ubuntu starts. Thanks.

  • Are you sure you're running bash? `/bin/sh` links to `dash` in recent Ubuntu. – choroba Jun 27 '16 at 11:56
  • Right. It links to dash, which I didn't know. (1) Shall I put the change to `PATH` in `~/.profile`? (2) How does one find out what the current running shell is, e.g. bash, dash, zsh? – Tim Jun 27 '16 at 12:06

You should put your environment variables in ~/.profile.

In this file you can also place environment variable assignments, since it gets executed automatically by the DisplayManager during the start-up process desktop session as well as by the login shell when one logs in from the textual console.
