If not, they won't see that change. My guess is that you started the IDEs from your GUI in some way (the Applications menu or something). If that's the case, they'll inherit their environment from your GUI. You _may_ be able to have them "notice" your change to .bashrc by logging out and in again, or rebooting; it depends how your system is configured. ChrisA
