A log file viewer for the terminal

Merge, tail, search, filter, and query log files with ease.

No server. No setup. Still featureful.

Try it out:

$ ssh playground@demo.lnav.org

In Your Terminal

Many logging tools, like Splunk, provide great features but are optimized for large-scale deployments. They require installing and configuring servers before they can be effectively used. There is still a need for a robust log file analyzer for the terminal.

Easy to Use

Just point lnav to a directory and it will take care of the rest. File formats are automatically detected and compressed files are unpacked on the fly.

Improved Presentation

Log files are a wealth of information, lnav can help highlight the parts that are important and filter out the noise.
