Might I pose a little question here, being a total IT noob?
I run Kubuntu (Ubuntu with the KDE desktop) on an old pc and all works well, but I noticed that the amount of free hard drive space is slowly declining;
Last week there was 333.4 GB free, and currently there is still 331.2 GB left? It should be noted I haven't installed any packages/games since then, so I'm assuming that space is being slowly eaten away by updates on stuff I have installed?
So I was wondering if that was indeed the case, (because 2 GB in a week's time is a bit big for just updates on like 30 packages methinks), and if there is some sort of "cleanup" method just in case older obsolete stuff is still about and clogging the pc up?
It is nothing drastic, of course, as 331 GB of free disc space is still like 3/4 of the drive, but I got me wondering as too what was eating that tidbit of free space?
Could be updates, could be runaway logging. I once had an app go crazy and balloon the .xsession-errors
file in my home directory up to over a gigabyte in size before I noticed. (Keep in mind that files won't actually be deleted if they're still in use, so you have to delete the log file and
kill the application to free any such space)
If you don't mind installing a KDE application, I recommend Filelight for identifying what's using up your space. It draws a very nice interactive radial graph. (GNOME added an inferior clone of it to Baobab, but it really is inferior. For example, Filelight makes heavy use of caching and selective re-scan to make itself a more viable solution for scanning and pruning really large swathes of files.)
Another good tool for that sort of thing is ncdu, which gives you a terminal-based view in the form of a sorted-by-size listing which you can navigate and drill down into using the arrow keys.
