Path To New Root / Run Command As New Root

Executes a specified command within a defined chroot environment for strict isolation.
sudo chroot <path/to/new_root> <command> sudo chroot <path/to/new_root> <command> #!/bin/bash
# Run Command As New Root
sudo chroot {{path/to/new_root}} {{command}} import subprocess
# Run Command As New Root
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"path-to-new_root",
"chroot",
"<path/to/new_root>",
"<command>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: path-to-new_root not found. Please install it first.")

run_command() When To Use
When executing specific commands in a segregated environment to prevent interaction with the main file system.
Pro Tip
Set the environment variables inside chroot to avoid unexpected behavior; `env -i` can help in certain contexts.
