logwriter

logwriter

A Go-based log management utility that wraps command execution, captures output to log files, and automatically manages log retention based on time and disk space constraints.

Features

• Wraps any command and captures stdout/stderr to dated log files
• Automatic log rotation based on age or disk space
• Flexible log naming patterns (flat or hierarchical)
• Cron-based scheduled cleanup
• Zero application changes required
