如何将终端限制在 chroot 中的目录中？

  • 772

我想暂时将特定目录设置为顶级目录。假设我打开终端，/home/me/mychroot如何将mychroot目录设置为该终端的顶级目录？

gnome-terminal

  1. 要更改工作目录，请尝试使用以下命令

    gnome-terminal --working-directory=/path/to/dir

    您可以使用命令检查更改是否已生效pwd。

    或者，打开“~/.bashrc”，滚动到底部并添加更改目录命令 -

    cd ~/mychroot

    最接近我的问题的解决方案是proot但它没有按预期工作。例如当我运行它时

    proot -w  ~/mychroot

    当我切换到父目录时

    cd ..

    并运行

    ls

    它真的改变到父目录，它必须限制在~/mychroot目录中

    无论如何，我在其中一个论坛中找到了一个脚本并根据我的需要对其进行了修改。在原始脚本中它不起作用，/usr/sbin/chroot我将其替换为fakechroot fakeroot chroot并添加了一些新行。

    #!/bin/bash

if [ $# -ne 1 ]; then
  echo "Usage: $0 <enter_name_of_your_chroot_directory>"
