tail
nxadm/tail is a Go package that emulates the BSD tail program, enabling applications to read from continuously updated files (tail -f). It supports file truncation and movement detection, making it suitable for use with log rotation tools. The library works across all Go-supported operating systems, including Linux, BSD, macOS, and Windows, and requires Go 1.12 or newer. It is an actively maintained drop-in replacement for the abandoned hpcloud/tail library, continuing development with updated dependencies, improved documentation, and bug fixes. Users install it via go get and can easily follow log files by leveraging APIs for tailing files, reading new lines as they appear, and reopening files after rotation. Example usage includes monitoring log files such as nginx access or error logs.
