Linux 查看磁盘分区、文件系统、使用情况的命令和相关工具介绍df（国外英文资料） See the hard disk usage under Linux One, the df-l command The df comes from the coreutils package and comes with the system installation. This command allows you to view the use of the disk and the location of the file system mount; [root @localhost ~] # df-l File system capacity already available already use % mount point / dev/sda3 4956316 35635650881135396 / TMPFS 24132012241308 1/dev/SHM / dev/sda6 4806904, 2523708 2039012 56% / media/disk / dev/sda1 4956284 3529796 796 76 / media / _ / dev/sda5 4845056 2581484 / media/disk -1 You can see that the system hangs on sda3 and also hangs the sda6 / sda1 / sda5 system. Two, fdisk -l commands Fdisk is a powerful disk operating tool, from the util-linux package, where we only say how he views the disk partition table and the partition structure. Through the -l parameter, you can obtain the partition of all the hard disks in the machine; [root @localhost ~] # fdisk - l Disk/dev/sda: 40.0 GB, 40000000000 bytes 255 heads, the 63 sectors/track, 63 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0 x62a9f8d0 Device Boot End Blocks Id System / dev/sda1 * 1 637 5116671 83 Linux /dev/sda2 638 891 2040255 82 Linux swap/Solaris / dev/sda3 892 1528 5116702 + 83 Linux / dev/sda4 1529 2744 9767520 5 Extended /dev/sda5 1529 2136 4883728 + 83 Linux /dev/sda62137 2744 4883728 + 83 Linux Sda1 is the partition of the MBR (master boot record); Sda2 is the swap partition; Sda4 is an extended partition, including sda5, sda6 logical partitions. Dividing partition system can only be divided into four primary partitions (Extended partition is also the primary partition), I in the above points, the three primary partition + 1 Extended partition, 5.6 is a logical partition. So there will be sda1.2.3.4.5.6. If you have only one primary partition + 1 extension partition, the logical partition starts with sda5, sda1.2.5.6... Third, cfdisk - Ps command (note that P is uppercase)
