tail

A drop-in replacement for the system tail command that also logs all output to the systemd journal.

Installation

cargo install --git https://github.com/worthies/tailing

Usage

# Pipe any command output through tail
some_command | tail

# View logs in journalctl
journalctl -f -t tailing

Features

• Drops in as a replacement for /usr/bin/tail
• Logs all input lines to systemd journal with identifier tail-<PPID>
• Streams input in real-time (line-by-line)
• Prints the tag to stderr for easy identification

How It Works

1. Reads stdin line by line
2. For each line:
   • Logs to systemd journal via /usr/bin/logger -t tail-<PPID>
   • Pipes to /usr/bin/tail for standard output
3. Tag is printed to stderr at startup
