    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}}
