I Login / Launch Shell As Superuser Login
Launch Shell As Superuser Login
Initiate a login shell for superuser to perform administrative tasks as root.
sudo -i sudo -i #!/bin/bash
# Launch Shell As Superuser Login
sudo {{[-i|--login]}} import subprocess
# Launch Shell As Superuser Login
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"i---login",
"-i"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: i---login not found. Please install it first.")

run_command() When To Use
