Q. I’d like to see all the partitions on my scsi hard drives. Under Windows Disk manager shows exactly how space is allocated on the disk drivers and free space etc. How do I display hard drive partitions information?
A. You can use any one of the following command:
[a] fdisk command : Partition table manipulator for Linux
[b] GNU Parted : a partition manipulation program
fdisk -l command
To list the partition tables for the specified devices and then exit. If no devices are given, those mentioned in /proc/partitions (if that exists) are used i.e. it will try to display all partitions, enter:
$ sudo fdisk -l
OR
# fdisk -l
Output
Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000f1a3e Device Boot Start End Blocks Id System /dev/sda1 * 1 12749 102400000 7 HPFS/NTFS /dev/sda2 12750 24906 97651102+ 83 Linux /dev/sda3 24907 25149 1951897+ 82 Linux swap / Solaris /dev/sda4 25150 60802 286375936 f W95 Ext'd (LBA) /dev/sda5 25150 60802 286374912 7 HPFS/NTFS
GNU parted command
Pass print option to displays the partition table, enter:
$ sudo parted /dev/sda print
