在我的Fedora 14开发人员计算机上,我可以将一个sharedAliases.sh文件添加到/etc/profile.d – 我的用户和root用户都可以访问共享别名.
切换到远程CentOS 5.7机器,看起来完全相同的配置,没有骰子,root用户无法访问共享别名.
这可能是因为我通过SSH进入CentOS盒子,不确定.无论如何,蹩脚的解决方法是将共享别名复制到root用户的.bashrc中,因为这是我能够获得所需的prefs到root的唯一方法(是的,我知道我应该sudo,但是一直在用su滚动年份).
赞赏的想法,如果可能的话,宁愿不必复制别名.
解决方法
Must have to do with diff between su-ing over ssh vs when logged
directly into machine
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
$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 total 226540 -rw-rw-r-- 1 root root 60148987 Apr 1 2011 3241948.flv
