fdisk on my list of applications to include, and I suppose it warrants inclusion, even if I have a personal reason for writing about it. This is out of util-linux, not coreutils, which is a change … over the past few days, anyway.
Or maybe not.
fdisk is a tool for “creating and manipulating partition tables,” which means two things — first, it doesn’t belong in coreutils ; and second, it has the potential to completely destroy your system if you use it wrong.
Of course, you could say that about a lot of things. That doesn’t mean
fdisk is something you should avoid. Live a little. Don’t be afraid to try something new. If you need a completely sterile, padded and antiseptic existence, I hear Windows 8.1 is a lot like a child’s pull toy.
The easiest and probably most popular use for
fdisk is checking what hard drives are connected to your computer. As you can see in the screenshot, if you tack on the
-l flag, you’ll get a neatly formatted list of drives and partitions, along with sensitive and personal information for each.
fdisk can also manipulate or create partitions, and if you start it and aim it at a device label, you’ll have the option to delete, create, modify or adjust partitions on that device.
I suppose it should go without saying that you’ll need superuser permissions or root account access to do any real damage to your system. And for goodness sake and all that is holy, don’t use
fdisk lightly. And don’t complain to me if you destroy your collection of family photos by tinkering with the partitions on your external drive.
There’s more you can do with
fdisk, but I should probably admit that when it comes time to arrange partitions, on a new drive or at installation time. I usually rely on
cfdisk, which is also part of util-linux.
I know there are hard-core Linux geeks out there who wouldn’t dream of using anything but
fdisk to set up a drive, just like they wouldn’t dream of using anything but ed to edit a text file.
I just prefer the arrangement and the dialogs. It’s more intuitive for me.
So what’s my personal reason for including
fdisk here? Well, you see,
fdisk got something lately — in version 2.24 in Arch — that I really like. And if you looked at the screenshot you probably already know what it is. …
P.S., sorry, Debian fans. You’re still stuck at 2.20 in Wheezy. …
