logmux

Logmux tails multiple log files, labels their lines and outputs everything in one stream - Much like docker-compose, but simply for local log files!

Installation

pip install logmux

Usage

logmux first.log second.log test/third.log

This will tail all three log files. New lines will be prefixed with the name of the log file it came from, e.g. first: for the first log file and third: for the last one.

You can customize the labels by providing them as a query parameter for each file:

logmux "first.log?label=custom" second.log test/third.log

This will prefix all lines from the first file with custom: . You'll need to quote the argument like in this example to make sure that your shell is not going to split it.

It's also possible to set the color of the label:

logmux "first.log?label=custom&color=blue" "second.log?color=red" test/third.log
