The chroot
command in Linux/Unix allows you to change the root directory for a process and its child processes. This can be useful in several scenarios, such as system recovery, testing, or sandboxing.
Here are some examples of using the chroot
command:
- Change the root directory to a new location: The following command changes the root directory to
/newroot
:
sudo chroot /newroot
- Change the root directory and start a shell: The following command changes the root directory to
/newroot
and starts a new shell:
sudo chroot /newroot /bin/bash
- Change the root directory and run a command: The following command changes the root directory to
/newroot
and runs thels
command:
sudo chroot /newroot ls
Note: To use the chroot
command, you need to have root privileges. Also, make sure that the target root directory contains all the necessary files and directories, such as /bin
, /lib
, and /dev
, for the process to run properly.
