Commands to check hard disk partitions and disk space on Ubuntu

Here we are going to check some command that can be used to check up the partitions on your system.

The commands would check what partitions there are on each disk and other details like the total size, used up space and file system etc.

Commands like fdisk, sfdisk and cfdisk are general partitioning tools that can not only display the partition information, but also modify them.

1. fdisk

Fdisk is the most commonly used command to check the partitions on a disk. The fdisk command can display the partitions and details like file system type

Each device is reported separately with details about size, seconds, id and individual partitions.

2. sfdisk

Sfdisk is another utility with a purpose similar to fdisk, but with more features.

3. cfdisk

Cfdisk is a linux partition editor with an interactive user interface based on ncurses. It can be used to list out the existing partitions as well as create or modify them.

4. parted

Parted is yet another command line utility to list out partitions and modify them if needed.
Here is an example that lists out the partition details.

5. df

Df is not a partitioning utility but prints out details about only mounted file systems. The list generated by df even includes file systems that are not real disk partitions.

6. pydf

Improved version of df, written in python. Prints out all the hard disk partitions in a easy to read manner.

pydf is limited to showing only the mounted file systems.
