is there a sleep command that works with real date time and ignores suspend?
In Linux and other Unix-like operating systems, there isn't a built-in `sleep` command that works with real date and time while ignoring system suspend or sleep states. The `sleep` command is designed to pause the execution of a script or program for a specified number of seconds, but it doesn't consider system suspend or real-time clock changes. If you need a script or program to wait until a specific date and time, you can use a scripting language like Python or Perl to calculate the time difference and implement a custom sleep mechanism that takes real-time changes into account. Here's an example using Python: ```python import time from datetime import datetime # Define the target date and time target_datetime = datetime(2023, 10, 31, 12, 0, 0) # Replace with your desired date and time # Calculate the time difference time_difference = target_datetime - datetime.now() # Ensure time_difference is positive if time_difference.total_seconds() > 0: # Sleep until the t
