Here’s another one that will probably be more interesting to administrators or multi-user system fans: logintop10.
It should be fairly obvious what’s happening there: logintop10 parses through your wtmp file (which was at /var/log/wtmp on my Arch system) and comes back with an array of login statistics. Output is to an HTML file of your choosing, with very clean formatting and with a little color here and there.
As far as I can see, there’s no way to adjust the exact output that logintop10 shows, unless you’re willing to manhandle the results. There is an option to “dump raw data,” but that really only adds on a full list of logins to the output page. If you’re on a big system that would create a file of considerable length, so I can see why it’s not enabled by default.
Either way, wtmp is in a binary format that will require some sort of tool to read, so logintop10 is doing you a favor and sifting through the data file, then arranging it in a prettified fashion.
logintop10 comes from the same author as genstats, and so perhaps the two might be useful in tandem.
In AUR, but not in Debian. There is a prebuilt .deb file on the home page though. 😉
