In Windows I could easily do this by navigating the directory tree and looking at the sizes. But in Linux, you need to run a command and, what's worse, it takes a lot of time:
$ du -sh /some/dir
I'm using a disk of 1 TB, but for some reason I only have like 50 GB left, and I can't seem to find what's taking so much space.
I remember that in Ubuntu I had to manually remove old kernel images. But now I'm on Fedora and dpkg -l | grep linux-image
doesn't work, and I guess Fedora removes them automatically anyway.
Any ideas?
