If you plan on adding a new disk in the future, learning how to partition will come in handy. Linux supports the following partitioning tools:
Fdisk Tools – This is composed of the text-based tools: fdisk, cfdisk, and sfdisk. These tools are great for use in partitioning. However, it could be a bit overwhelming for beginners who are not yet familiar with partitioning.
libparted Tools – The libparted library presents both GUI and text-based partitioning tools. One particular example is GParted as shown in the screenshot below. The interface makes it easier to use for beginners.
GPT fdisk Tools – These are tools created for GPT (Globally Unique Identifier Partition Table) disks using the fdisk tools.

Here are some commands that you can use to check the existing disk space on your computer:
| Commands | What it does |
| df -h | This command displays the disk space usage in all of the mounted devices. The -h option presents the results in a human-readable output, using G for gigabytes or M for megabytes sizes. |
| du /home/edulaney/files/ | This command displays all the files inside the specified directory and their corresponding file sizes. You can also specify a filename. |
| du -s /home/edulaney/files/ | The –s option provides the total file size of the specified directory |
