Python: Archive Old Logs by Compressing Gzip by Age
A Python script that finds .log files older than a specified age and compresses them into .gz archives while removing the originals.
import gzip
import os
import shutil
from pathlib import Path
def archive_logs(log_dir: str, max_age_days: int) -> list[str]:
"""Compress log files older than max_age_days into .gz archives.
Returns a list of compressed file paths.
"""
cutoff = time.time() - max_age_days * 86400

This script restricts a secrets file to 0600 permissions, rotates it to a dated backup, and creates a fresh protected file for secure automation workflows.
import os
import sys
import stat
from pathlib import Path
def restrict_secrets_file(filepath: str) -> None:
"""Set restrictive permissions (0600) on a secrets file."""
path = Path(filepath).expanduser()
if not path.is_file():
raise FileNotFoundError(f"Secrets file not found: {path}")
