Linux :: /etc/profile.d中的共享别名未应用于root用户,为什么？

我怀疑你执行没有破折号( – )的su命令,如果是这样,它将调用一个交互式非登录shell.与你结合只有在/root/.bashrc中关注：

# Test for an interactive sHell.  There is no need to set anything
# past this point for scp and rcp,and it's important to refrain from
# outputTing anything in those cases.
if [[ $- != *i* ]] ; then
    # SHell is non-interactive.  Be done Now!
    return
fi

(不是源/ etc / bashrC)

而如果您直接登录或使用su –,它将调用登录sHell,读取/ etc / profile并执行sharedAliases.sh.

要查看使用不同sHell读取的文件,请通过以root身份执行以下命令将日志添加到所有这些文件：

echo "echo 'running /etc/bashrc'" >> /etc/bashrc
echo "echo 'running /etc/profile'" >> /etc/profile
echo "echo 'running /root/.bashrc'" >> ~/.bashrc

创建测试别名：

# echo "alias list='ls'" > /etc/profile.d/test.sh

现在,以普通用户身份登录并使用su,您将看到如下内容：

$su
password: 
running /root/.bashrc
bash-3.2# list
bash: list: command not found

和su – ：

$su -
password: 
running /etc/profile
running /root/.bashrc
# list
