Dave, I know how to check for free disk space on Windows XP, but how do I check for the amount of free disk space available on a machine running Linux (CentOS, Fedora, Red Hat, Ubuntu, etc.)?

I'm perpetually running out of disk space on my computers. If you follow me on Twitter (I'm @DaveTaylor), you've probably seen me every so often send out a message asking about this, that or the other upgrade path for one of my computers because things are filling up.

That's why when I saw that TechRestore was offering a 500GB internal drive upgrade path for my trusty MacBook Pro, I was quite interested. My existing drive at the time was only 149GB in size (that's actual usable size) and it was about 90% full, and that was with me sporadically pruning everything.

I contacted Shannon Jean at TechRestore and asked if they'd run an upgrade for me so I could see how the process worked, in return for me sharing the experience with you, my readers, and they agreed.

Here's how it went...
