Today I needed to partition an additional hard disk and format the partitions. I used
cfdisk which is installed by default on Ubuntu to have a nice text GUI and not the plain old
fdisk. But after changing the partition table and exiting cfdisk you’ll see that the entries in
/dev/ are still missing for the new partitions. Sure you can reboot or reconnect hot plug devices like the onces connected via USB. But thats not elegant nor in the best Unix tradition. 😉
partprobe for discovering new partitions, just enter it as user with root privileges and the devices will be created and you can use
mkfs.[ext3|vfat|..] to format the partitions. If your system is missing it you can easily install it (on Ubuntu/Debian) like this:
apt-get install parted. I’ll guess the package is named similar on other distributions.
