  • Display information about a specific undo file:
    e2undo -h path/to/undo_file /dev/sdXN
  • Perform a dry-run and display the candidate blocks for replaying:
    e2undo -nv path/to/undo_file /dev/sdXN
  • Perform an undo operation:
    e2undo path/to/undo_file /dev/sdXN
  • Perform an undo operation and display verbose information:
    e2undo -v path/to/undo_file /dev/sdXN
  • Write the old contents of the block to an undo file before overwriting a file system block:
    e2undo -z path/to/file.e2undo path/to/undo_file /dev/sdXN
