Editor to share with you how to use the disk space management tools of the Linux system. I hope you will get something after reading this article. Let's discuss it together.

1.fdisk-l

Disk / dev/sda: 120.0 GB, 120034123776 bytes = > 120g hard disk capacity

14593 heads, 63 sectors/track, 14593 cylinders = > 255 heads, 63 sectors, 14593 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes = > the capacity of each cylinder is 8225280

= > Storage capacity = number of tracks (cylinder) × number of heads × number of sectors x bytes per sector

14593 × 255x63 × 5129111.788G

Cylindrical capacity = number of heads × number of sectors x bytes per sector 255 × 63 × 512 8225280 B

In fact, hard disk manufacturers usually calculate according to 1G=1000.

Disk identifier: 0xc3ffc3ff

A partition represented by Device Boot Start End Blocks Id System = > start starts with X cylinder

/ dev/sda1 * 1 3824 30716248 + 7 HPFS/NTFS

/ dev/sda2 3825 10199 51200000 7 HPFS/NTFS

/ dev/sda3 10200 12596 19253902 + 5 Extended

/ dev/sda4 12597 14593 16040902 + 12 Compaq diagnostics

/ dev/sda5 10200 10211 96358 + 83 Linux

/ dev/sda6 10212 10454 1951866 82 Linux swap / Solaris

/ dev/sda7 10455 11548 8787523 + 83 Linux

/ dev/sda8 11549 12596 8418028 + 83 Linux

2.df: you can check the disk usage and where the file system is mounted through this command

Filesystem 1K-blocks Used Available Use% Mounted on

/ dev/sda7 8649544 1986948 6223220 25 /

Tmpfs 1033648 0 1033648 / lib/init/rw

Udev 10240 136 10104 / dev

Tmpfs 1033648 0 1033648 / dev/shm

/ dev/sda5 93307 19997 68493 23% / boot
