阅读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.
其他外壳也加载~/.profile
(zsh,tcsh)..因此,我会将环境内容放入~/.profile
。
