The command "sudo e2fsck ${-dev-sdXN}" is used to run the e2fsck command with administrative privileges to check and repair the filesystem on a specific Linux partition.

Here's a breakdown of the command:

• "sudo" is a command in Linux that allows a user to run programs with the security privileges of another user, usually the superuser (root). In this case, it grants administrative privileges to run the subsequent command.

• "e2fsck" is a command-line utility in Linux used to check and repair ext2, ext3, and ext4 filesystems. It scans the specified partition for errors and attempts to fix them.

• "${-dev-sdXN}" is a placeholder that represents the device node for the specific partition you want to check. Replace it with the actual path of the target partition. The format typically follows the pattern "/dev/sdXN", where "X" denotes the specific drive letter (e.g., a, b, c) and "N" represents the partition number.

So, when you run the command with the appropriate device node, for example, "sudo e2fsck /dev/sda1", it will check and repair the filesystem on the specified partition using administrative privileges.
