arch-chroot:tldr:4e854

The command arch-chroot ${path-to-new-root} ${zsh} is used in Arch Linux to create a new chroot environment using the specified path as the new root directory, and then execute the zsh shell within that environment.

Let's break it down:

1. arch-chroot: It is a utility in Arch Linux used to change the root directory temporarily, creating a minimal environment similar to a complete Linux distribution. It allows running commands as if you were in a different system while still interacting with the host system.

2. ${path-to-new-root}: This is the placeholder for the actual path to the directory that will become the new root. It specifies the location where the chroot environment will be set up. For example, it might be /mnt if you are setting up a chroot environment for a mounted partition.

3. ${zsh}: Similarly, this is a placeholder representing the shell that will be executed within the chroot environment. In this case, zsh refers to the Z Shell, which is an alternative to the default bash shell.

So, when you run the command arch-chroot ${path-to-new-root} ${zsh}, it will create a new chroot environment using the specified path as the root. Then, it will launch the zsh shell within that environment, allowing you to execute commands and interact with the chrooted system.
