Question

我尝试将PATH导出到/etc/bash.bashrc文件，但我添加了一些无效的标识符。现在我无法从终端访问诸如ls，nano，vi，gedit等程序，这就是为什么无法更正/etc/bash.bashrc文件的原因。在这种情况下如何编辑它？谢谢！

Answer 1

在我的Ubuntu上， nano 和 vi 程序存在于 / usr / bin 中。所以你可以试试

$ sudo /usr/bin/nano /etc/bash.bashrc
$ sudo /usr/bin/vi /etc/bash.bashrc

Answer 2

你可以做以下两件事之一：

1）使用vi的完整路径编辑/etc/bash.bashrc文件：

/usr/bin/vi /etc/bash.bashrc

2）更正命令行上的路径然后修复：

export PATH=...
vi /etc/bash.bashrc

$ cat /etc/bash.bashrc 
# System-wide .bashrc file for interactive bash(1) shells.

# To enable the settings / commands in this file for login shells as well,
# this file has to be sourced in /etc/profile.

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.

Answer 4

您可以在命令行中指定完整路径，例如

$ /usr/bin/nano /etc/bash.bashrc

这样你可以拉起纳米并编辑它。

Answer 5

您还可以尝试运行/bin/sh以获得“标准”shell。

搞砸了“/etc/bash.bashrc”无法再次编辑它
