我很困惑,我应该在哪里设置环境变量?
在 .profile 中还是在 .bash_profile 中?
我同时使用 mac osx 和 ubuntu。
我很困惑在这里使用哪一个。

读http://www.gnu.org/software/bash/manual/bashref.html#Bash-Startup-Files:
When Bash is invoked as an interactive login shell, or as a
non-interactive shell with the --login option, it first reads
and executes commands from the file /etc/profile, if that file
exists. After reading that file, it looks for ~/.bash_profile,
~/.bash_login, and ~/.profile, in that order, and reads and executes
commands from the first one that exists and is readable. The
--noprofile option may be used when the shell is started to inhibit
this behavior.
其他 shell~/.profile
也会加载 (zsh、tcsh)... 所以,我会将环境内容放入其中~/.profile
。
mac osx 相关更新(感谢@Matt B):
对于 GUI 程序,请阅读http://developer.apple.com/library/mac/#qa/qa2001/qa1067.html并~/.MacOSX/environment.plist
仔细编辑。

如果你使用 bash,则在~/.bash_profile
。如果你使用其他 shell,则在~/.profile
