Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Export log to html file

Logtool is a nice tool that can export log file to various format, but its strength lies in the capacity of colorize logs. This command take a log as input and colorize it, then export it to an html file for a more confortable view. Logtool is part of logtool package.Tested on Debian.


There is 1 alternative - vote for the best!

Terminal - Alternatives
x="/tmp/auth.html";sudo cat /var/log/auth.log | logtool -o HTML >$x;xdg-open $x;rm $x

Functions: cat rm sudo

similar to previous except this exports to a temporary file, opens that file with your default web browser, then deletes it.

Know a better way?
