The strip command removes the specified changesets and all their

descendants. If the working directory has uncommitted changes, the
|
|
|
operation is aborted unless the --force flag is supplied, in which
|
|
|
case changes will be discarded.

If a parent of the working directory is stripped, then the working

directory will automatically be updated to the most recent

|
available ancestor of the stripped parent after the operation
|
|
|
completes.
|
|
|
|
|
|
Any stripped changesets are stored in ``.hg/strip-backup`` as a
|
|
|
bundle (see :hg:`help bundle` and :hg:`help unbundle`). They can
|
|
|
be restored by running :hg:`unbundle .hg/strip-backup/BUNDLE`,
|
|
|
where BUNDLE is the bundle file created by the strip. Note that
|
|
|
the local revision numbers will in general be different after the
|
|
|
restore.
|
|
|
|
|
|
Use the --no-backup option to discard the backup bundle once the
|
|
|
operation completes.
|
|
|
|
|
|
Strip is not a history-rewriting operation and can be used on
|
|

changesets in the public phase. But if the stripped changesets have
|
|
|
been pushed to a remote repository you will likely pull them again.
