ztail

Like the linux tail command but for gzip compressed files

Usage

Tail a file

By default the functionality of -f is emulated

./ztail ~/test.log.gz

Stop following a file:

Ctrl+C

Build

• Install Crystal
• Checkout this repo
• Build with: crystal build --static --release ztail.cr
• Or with docker/podman docker run --rm -it -v $(pwd):/workspace -w /workspace crystallang/crystal:latest-alpine crystal build --static --release ztail.cr

Known issues

• High CPU usage as it needs to re-read the gzip file in every iteration (this is because plain gzip do not support random access)
