Change Log

2023-04-28: Version 23.04.28

• Cleaned up the output.

2022-06-14: Version 22.05.30

• Added checks and balances to help with configuration as I'm very aware that the initial configuration can be troublesome. Running the utility manually is a lot more friendly and step-by-step now.
• Added -Help to give usage instructions in the terminal. Running the script with no options will also trigger the -help switch.
• Cleaned user entered paths so that trailing slashes no longer break things or have otherwise unintended results.
• Added -LogRotate [days] to removed old logs created by the utility.
• Streamlined config report so non configured options are not shown.
• Added donation link to the ASCII banner.
• Cleaned up code, removed unneeded log noise.

2021-12-08: Version 21.12.08

• Configured logs path now is created, if it does not exist.
• Added OS version info.
• Added Utility version info.
