In this section of the tool, I added the utility functions that we will reuse throughout the source code. These functions are shown in the following bullet list:

• For printing the separators lines, use the following:

separator_single_line = '------------------------------------------------------------'
separator_double_line = '============================================================'

• For printing the colored texts on the Terminal window, use the following:

# Printing Red Text for errors
def print_red(text): print("33[91m {}33[00m".format (text))


# Printing Green Text for messages
def print_green(text): print("33[92m {}33[00m".format (text))


# Printing Yellow Text for warnings
def print_yellow(text): print("33[93m {}33[00m".format (text))

• For saving the report results to a file, use the following:

def save_results(results, folder_name, file_name):
    try:
        # Save the results to a folder/file
        file_name_path = folder_name + "/" + file_name

        # If the folder does not exist then create it
        if not os.path.isdir (folder_name):
            os.mkdir (folder_name)

        # Create the file object
        file_to_save = open (file_name_path, 'w')
        # Make sure the output is correctly encoded
        results = results.encode ('utf-8')
        # Write the changes
        file_to_save.write (results)
        # Close file object
        file_to_save.close ()
    except Exception, e:
        exception_message = str (e)
        print_red ('[!] Error: Cannot save the results to a file! Reason:
' + exception_message)

• To execute a Terminal window command, use the following:

def execute_cmd(tool_name, cmd):
    start_msg = "[+] Starting %s ..." % tool_name
    print_green (start_msg)
    # The output variable that stores the output from the command line
    output = ''

    try:
        # Cleanup the command string
        cmd = cmd.rstrip()
        # Execute the command
        output += subprocess.check_output(cmd, shell=True, stderr=subprocess.STDOUT)
        # Add a new line
        output += '
'
    except Exception, e:
        exception_message = str (e)
        output += exception_message
        print_red ("[!] Error executing the command: " + cmd + " Reason:
" + exception_message)
        output += '
'

    output += separator_single_line + '
'

    end_msg = "[+] Finished %s ..." % tool_name
    print_green (end_msg)
    return output

• To print error messages after the command's execution, use the following:

def error_execution(tool_name): print_red ("Error Executing " + tool_name)
