The "redo" command:

Usage: fossil undo ?OPTIONS? ?FILENAME...?
   or: fossil redo ?OPTIONS? ?FILENAME...?

Undo the changes to the working checkout caused by the most recent
of the following operations:

   (1) fossil update             (5) fossil stash apply
   (2) fossil merge              (6) fossil stash drop
   (3) fossil revert             (7) fossil stash goto
   (4) fossil stash pop

The "fossil clean" operation can also be undone; however, this is
currently limited to files that are less than 10MiB in size.

If FILENAME is specified then restore the content of the named
file(s) but otherwise leave the update or merge or revert in effect.
The redo command undoes the effect of the most recent undo.

If the -n|--dry-run option is present, no changes are made and instead
the undo or redo command explains what actions the undo or redo would
have done had the -n|--dry-run been omitted.

A single level of undo/redo is supported.  The undo/redo stack
is cleared by the commit and checkout commands.

Options:
  -n|--dry-run   do not make changes but show what would be done
