hg bisect [-gbsr] [-U] [-c CMD] [REV]

subdivision search of changesets

    This command helps to find changesets which introduce problems. To use,
    mark the earliest changeset you know exhibits the problem as bad, then
    mark the latest changeset which is free from the problem as good. Bisect
    will update your working directory to a revision for testing (unless the
    -U/--noupdate option is specified). Once you have performed tests, mark
    the working directory as good or bad, and bisect will either update to
    another candidate changeset or announce that it has found the bad

    As a shortcut, you can also use the revision argument to mark a revision
    as good or bad without checking it out first.

    If you supply a command, it will be used for automatic bisection. Its exit
    status will be used to mark revisions as good or bad: status 0 means good,
    125 means to skip the revision, 127 (command not found) will abort the
    bisection, and any other non-zero exit status means the revision is bad.

    Returns 0 on success.
