The command "resize2fs -M ${-dev-sdXN}" is used to resize the file system to the minimum size possible on a specific partition or device.

Here's a breakdown of each part of the command:

• resize2fs: This is the command used to resize the ext2, ext3, or ext4 file systems.
• -M: This option tells the command to resize the file system to the minimum possible size.
• ${-dev-sdXN}: This is a placeholder for the actual device and partition name. You need to replace ${-dev-sdXN} with the appropriate device and partition identifier, such as /dev/sdXN. For example, if you want to resize the file system on the device /dev/sda1, the command would be "resize2fs -M /dev/sda1".

In summary, the command is used to shrink the file system of a specific device or partition to its minimum size.
