bash.bashrc文件改坏了,shell无法用,有方法改过来不

[wanxiu]

不小心执行sudo gedit /etc/bash.bashrc
在bash.bashrc文档末尾添加了
PATH=/opt/arm/bin:

未加全，直接保存退出后.打开终端发现bash不好使了
出现如下信息
$ ls
bash: ls：找不到命令

sudo也不好使了
而且root用户被没有设置允许登入，只有usr用户.
无法改/etc/bash.bashrc文件

有方法改过来不

[JiangHui]

/usr/bin/sudo /usr/bin/gedit /etc/bash.bashrc

程序 'i' 尚未安装。 您可以通过输入以下命令安装：
sudo apt-get install iprint

请问你是想把bash.bashrc改回来吗?
