Screenshot of lnav

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.
