.profile 或 .bash_profile

.profile 或 .bash_profile

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。

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

对于 GUI 程序,请阅读http://developer.apple.com/library/mac/#qa/qa2001/qa1067.html~/.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
