在root下重构了自己的用户，然后用usermod修正了权限。
但是这个时候打开终端，发现原本应该显示
用户名@计算机名:"$
我这里显示的是$
看的别扭，这个怎么改回去。。

学习一下环境变量PS1吧。
echo $PS1
你那里显示的应该就是一个$
输入这个：
PS1="\u@"$hostname"'$' "
再输入bash，看看是不是好了，如果好了就把PS1="\u@"$hostname"'$' "写入~/.bashrc

$PS1就是管理这个事的
echo $PS1看看

明白了。。
不过我把PS1="\u@"$hostname"'$' "写入~/.bashrc文件尾，为什么不管用呢？

2ine 写了：明白了。。

重新打开终端

重新打开了，也没有出现～
我的方法是这样的：
sudo mousepad ~/.bashrc
手动加上那行，现在这个文件是这样的：

# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# update the values of LINES and COLUMNS.

PS1="\u@"$hostname"'$' "

楼上的命令，有什么意义呢？？

又小白了～
才反应过来~/就是自己的家目录。。
不过之前的家目录备份过，发现其中的.bashrc是一样的
那么二楼给的方法，很可能不成立～

顶～

2ine 写了：楼上的命令，有什么意义呢？？

你自己看看 /etc/skel 就知道

这个怎么了～和我原先的文件完全一样
替换后也是那样

你的“重构用户”什么意思？

这里已经有 PS1 的设置了

这是个问题。。。
重构用户，就是先userdel再useradd最后usermod

话说楼上那句我也看到了～但是很纳闷的，为什么不加载呢？
难道我RP不好。。

接着顶
