hg backout [OPTION]... [-r] REV

reverse effect of earlier changeset

Prepare a new changeset with the effect of REV undone in the current working directory.

If REV is the parent of the working directory, then this new changeset is committed automatically. Otherwise, hg needs to merge the changes and the merged result is left uncommitted.


backout cannot be used to fix either an unwanted or incorrect merge.

By default, the pending changeset will have one parent, maintaining a linear history. With --merge, the pending changeset will instead have two parents: the old parent of the working directory and a new child of REV that simply undoes REV.

Before version 1.7, the behavior without --merge was equivalent to specifying --merge followed by "hg update --clean ." to cancel the merge and leave the child of REV as a head to be merged separately.

See "hg help dates" for a list of formats valid for -d/--date.

Returns 0 on success, 1 if nothing to backout or there are unresolved files.
