I rewrote the bash installation script quite a bit. The main points are:
- default all users install is to /usr/local
- moved AUTOJUMP_DATA_DIR to ~/.autojump
- for OS X all users install, it doesn't prompt for permission creating /etc/profile.d/
- single user install is to ~/.autojump
- single user install tests for ~/.autojump/bin within .bashrc PATH command and adds it if necessary
One last note, one of the earlier commit says I combined cd and ls in the j command but I took that back out.
I tested all users and single user install on Ubuntu 10.04 Server, Ubuntu 10.10, OS X 10.6, and Debian 5.
