How to modify the partition format and size in Linux?

To modify the format and size of a Linux partition, you can follow these steps:

1. Firstly, open a command line terminal using tools such as fdisk or parted.
2. Use the fdisk -l or parted -l command to check the current partition status and locate the partition you want to modify.
3. Use the appropriate tool (such as fdisk or parted) to delete the partition you want to modify. For example, use the command fdisk /dev/sda to open the disk device, and use the d command to delete the specified partition.
4. Create a new partition by using the “n” command to specify the starting sector and size as prompted.
5. Save and exit using the w command.
6. Now, use the mkfs command to create a filesystem for the new partition. For example, use the mkfs.ext4 /dev/sda1 command to create an ext4 filesystem.
7. Use the mount command to mount the new partition to the appropriate directory. For example, use the command “mount /dev/sda1 /mnt/new_partition” to mount the new partition to the /mnt/new_partition directory.
8. Confirm that the partition has been successfully mounted; you can use the df -h command to check the usage of the partition.

Before performing any partition modification operations, be sure to back up important data to prevent data loss.
