• Planning for future storage needs: df can be used to plan for future storage needs. By tracking disk space usage over time, you can identify trends and forecast future storage requirements. This information can be used to make informed decisions about when to purchase additional storage.
• Troubleshooting disk space issues: df can be used to troubleshoot disk space issues. If you are experiencing problems with disk space, df can help you identify the root cause of the problem. For example, if you are unable to save a file to a particular file system, df can help you determine if the file system is full.

Overall, the df command is a valuable tool for checking hard disk size in Linux. It is easy to use and provides a wealth of information that can be used for a variety of purposes.

2. du – Estimates the amount of disk space used by files and directories.

The du command is a powerful tool for checking hard disk size in Linux. It provides a detailed breakdown of disk space usage by files and directories, making it easy to identify which files and directories are consuming the most space.

• Identifying space hogs: du can be used to identify files and directories that are consuming the most disk space. This information can be useful for a variety of purposes, such as freeing up disk space or migrating data to a larger storage device.
• Planning for future storage needs: du can be used to plan for future storage needs. By tracking disk space usage over time, you can identify trends and forecast future storage requirements. This information can be used to make informed decisions about when to purchase additional storage.
• Troubleshooting disk space issues: du can be used to troubleshoot disk space issues. If you are experiencing problems with disk space, du can help you identify the root cause of the problem. For example, if you are unable to save a file to a particular directory, du can help you determine if the directory is full.

Overall, the du command is a valuable tool for checking hard disk size in Linux. It is easy to use and provides a wealth of information that can be used for a variety of purposes.

3. fdisk – Displays information about disk partitions and their sizes.

The fdisk command is a powerful tool for checking hard disk size in Linux. It provides detailed information about disk partitions, including their size, type, and location on the disk. This information can be useful for a variety of purposes, such as:

• Identifying disk partitions: fdisk can be used to identify the different disk partitions on a system. This information can be useful for a variety of purposes, such as troubleshooting boot problems or recovering data from a damaged partition.
• Checking partition sizes: fdisk can be used to check the size of disk partitions. This information can be useful for planning for future storage needs or troubleshooting disk space issues.
• Creating and deleting partitions: fdisk can be used to create and delete disk partitions. This can be useful for a variety of purposes, such as resizing partitions or creating new partitions for different purposes.
• Changing partition types: fdisk can be used to change the type of a disk partition. This can be useful for a variety of purposes, such as converting a primary partition to a logical partition or vice versa.

Overall, the fdisk command is a valuable tool for checking hard disk size in Linux. It provides a wealth of information about disk partitions that can be used for a variety of purposes.
