4. /etc/profile
/etc/profile contains Linux system wide environment and startup programs. It is used by all users with bash, ksh, sh shell. Usually used to set PATH variable, user limits, and other settings for user. It only runs for login shell. If you wanted to make large changes or application specific changes use /etc/profile.d directory.
/etc/profile 包含 Linux 系统范围的环境和启动程序。所有用户都可以通过 bash、ksh、sh shell 使用它。通常用于为用户设置 PATH 变量、用户限制和其他设置。它只运行登录 shell。如果要进行大的更改或特定于应用程序的更改，请使用 /etc/profile.d 目录。

在 /etc/profile 文件中修改环境变量，修改的内容是对所有用户起作用的。在 /etc/profile 文件末尾添加如下环境变量。
Set up the development environment by modifying the PATH and LD_LIBRARY_PATH variables.
