Manage Old Log Files

Description​

The manage_old_files function manages log files in a specified folder by deleting the oldest files, keeping only the most recent ones. This is useful for log file rotation or limiting disk space usage.

Function Signature:​

def manage_old_files(folder_path: str, files_to_keep: int = 20, file_extension: str = '.log') -> None:

Parameters​

  • folder_path (str): The folder where the log files are stored.
  • files_to_keep (int): The number of most recent log files to keep. Default is 20.
  • file_extension (str): The file extension of the logs to manage. Default is .log.

Returns​

  • None: The function does not return any value.

Example Usage​

manage_old_files("/path/to/logs", files_to_keep=30, file_extension='.txt')

Notes​

  • The function lists all log files (by default .log files) in the specified folder.
  • Files are sorted by modification time, and the oldest ones are deleted until only the most recent files_to_keep are retained.

Error Handling​

  • If any error occurs (e.g., permission issues, failure to read the directory), the function will print the error message.
