cryptsetup:tldr:6470f

cryptsetup: Change the LUKS volume's passphrase.
$ cryptsetup luksChangeKey ${-dev-sda1}
try on your machine

The command you provided is attempting to change the encryption key for a LUKS (Linux Unified Key Setup) device.

Here is a breakdown of the command:

  • cryptsetup: This is the command-line utility for managing encrypted devices in Linux.
  • luksChangeKey: This is a sub-command of cryptsetup used to change the encryption key for a LUKS device.
  • ${dev-sda1}: This part seems to be a placeholder for the actual device name or path to the LUKS device. It should be replaced with the correct device name or path before running the command.

Overall, this command is meant to modify the encryption key for the LUKS device specified by ${dev-sda1}. The exact method of changing the key will depend on the LUKS setup and the specific arguments passed to the cryptsetup luksChangeKey command.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
