MacOSX 如何在 su - root 后自动运行脚本? [英] MacOSX how to autorun a script after su - root?

问题描述

假设我是普通用户，我将切换到 root:

Lets assume i am normal user, the i will switch to root:

user ~ $ su - root
Password: 
root ~ #

因此，一旦我以 root 身份登录，我希望 自动运行以下命令:

So once i logged in as root, i want to run following command automatically:

source .bash_profile

我怎样才能让上面的命令自动运行?

How can i have that above command run automatically please?

推荐答案

根据 bash 手册页，.bash_profile 是针对登录 shell 执行的，而 .bashrc 是为交互式非登录 shell 执行.

According to the bash man page, .bash_profile is executed for login shells, while .bashrc is executed for interactive non-login shells.

在您的情况下，您不需要像这样获取 .bash_profile .

In your case, you don't need to source .bash_profile like this.

您只需要将 source .bash_profile 放在根目录的 .bashrc 文件中

You just need to put source .bash_profile in your root's .bashrc file

if [ -f ~/.bash_profile ]; then
   source ~/.bash_profile
fi

echo "Testing .bashrc for a stack query"
[root@sgeorge-ld ~]# exit

[sgeorge@sgeorge-ld ~]$ su - root
Password: 
Testing .bashrc for a stack query
[root@sgeorge-ld ~]#
