v1.0.0 - Fast Decompression Tail for Compressed Files

First public release of ztail — a GNU-like command-line tool designed for fast access to the last lines of compressed files.

Features

• Supports .gz, .bgz, and .zip compressed files.
• Reads only the necessary portion of the file to retrieve the last N lines — avoiding full decompression.
• Performance up to 10x faster than zcat | tail in tests with large files.
• Simple CLI interface, compatible with typical tail usage.
• Uses efficient circular buffer implementation for memory management.

Usage example

ztail large_file.gz -n 20

Build

mkdir build && cd build
cmake ..
make

Notes

• Requires zlib and libzip installed on the system.
• Tested on Linux (GCC 13.3.0).
