# Script: 06 - Bash in Python
# Author: Robert Gregor
# Date of latest revision: 152030FMAR23

# Objectives
    # Create a Python script that executes a few bash commands successfully
        # Indicate in comments how you achieved this
    # Requirements:
        # Python module “os” must be utilized
        # At least three variables must be declared in Python that contain results of bash operations
        # Python function print() must be used at least three times
    # Include execution of the following bash commands inside your Python script:
        # whoami / ip a / lshw -short

# Stretch Goals
    # Instead of the os module, utilize the subprocess module instead
        # Refer to python.org for how this can be achieved

# Import subprocess module for shell command functionality
# Import click module for python screen clearing function () click.clear()

import subprocess
import click

# Main

# Declare variables equal to the output of running the subprocess.run command on specific bash commands
# capture_output=True ensures the capture of the output of the bash commands
# text=true ensures output is given as a string

who_am_i = subprocess.run(["whoami"], capture_output=True, text=True)
ip_a = subprocess.run(["ip", "a"], capture_output=True, text=True)
lshw_short = subprocess.run(["lshw", "-short"], capture_output=True, text=True)

# Clears screen

click.clear()

# Request user press the ENTER key to execute commands
# Prints the results of each command to the screen using stdout

input("Press Enter to run bash whoami command...\n")
print(who_am_i.stdout)

input("Press Enter to run bash ip a command...\n")

input("Press Enter to run bash lshw -short command...\n")

print("Script Complete!")
