How can I use system variables in my scripts?

You can access system variables in your scripts by using the appropriate syntax for your scripting language. For example, in Python, you can use the os module to access environment variables.

Can you give me an example of how to do that in Python?

Sure! Here's a simple example:

import os

# Get the value of the 'HOME' environment variable
home_directory = os.getenv('HOME')
print(f'Home Directory: {home_directory}')

What if I want to set a system variable in my script?

You can set environment variables in your script using the os.environ dictionary. For example:

import os
os.environ['MY_VAR'] = 'some_value'

Are there any limitations to using system variables?

Yes, system variables can vary between different operating systems, and some may not be accessible due to permissions or security settings.
