258 Part III . Choosing and Installing a Linux Distribution The following procedures are performed from the command line as root user. Remember that any partition commands can easily erase your disk or make it inaccessible. Back up critical data before using any tool to change partitions! Then be very careful about the changes you do make. Keeping an emergency boot disk handy is a good idea, too. The fdisk command is one that is available on many different operating systems (although it looks and behaves differently on each). In Linux, fdisk is a menu-based command. To use fdisk to list all your partitions, type the following (as root user): # fdisk l Disk /dev/hda: 40.0 GB, 40020664320 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 4833 38716650 83 Linux /dev/hda3 4834 4865 257040 82 Linux swap To see how each partition is being used on your current system, type the following: # df h Filesystem Size Used Avail Use% Mounted on /dev/hda2 37G 5.4G 30G 16% / /dev/hda1 99M 8.6M 86M 10% /boot none 61M 0 61M 0% /dev/shm From the output of df, you can see that the root of your Linux system (/) is on the /dev/hda2 partition and that the /dev/hda1 partition is used for /boot. If this had been a dual-boot system (with Windows 98), you might have seen a Windows partition from fdisk that looked like the following: /dev/hda1 * 1 83 666666+ b Win95 FAT32 You could mount that partition in Linux (to get to your Windows files when Linux is booted) by typing: # mkdir /mnt/win # mount -t vfat /dev/hda1 /mnt/win Before using fdisk to change your partitions, I strongly recommend running the df h command to see how your partitions are currently being defined. This will help reduce the risk of changing or deleting the wrong partition. Caution Note Caution
