etc/profile:此文件爲系統的每個用戶設置環境信息,當用戶第一次登錄時,該文件被執行.
並從/etc/profile.d目錄的配置文件中搜集shell的設置.
/etc/bashrc:爲每一個運行bash shell的用戶執行此文件.當bash shell被打開時,該文件被讀取.
~/.bash_profile:每個用戶都可使用該文件輸入專用於自己使用的shell信息,當用戶登錄時,該
文件僅僅執行一次!默認情況下,他設置一些環境變量,執行用戶的.bashrc文件.
~/.bashrc:該文件包含專用於你的bash shell的bash信息,當登錄時以及每次打開新的shell時,該
該文件被讀取.
~/.bash_logout:當每次退出系統(退出bash shell)時,執行該文件.
另外,/etc/profile中設定的變量(全局)的可以作用於任何用戶,而~/.bashrc等中設定的變量(局部)只能繼承/etc/profile中的變量,他們是"父子"關係.
~/.bash_profile 是交互式、login 方式進入 bash 運行的
~/.bashrc 是交互式 non-login 方式進入 bash 運行的
