hg resolve [OPTION]... [FILE]...

redo merges or set/view the merge status of files

    Merges with unresolved conflicts are often the result of non-interactive
    merging using the "internal:merge" configuration setting, or a command-
    line merge tool like "diff3". The resolve command is used to manage the
    files involved in a merge, after "hg merge" has been run, and before "hg
    commit" is run (i.e. the working directory must have two parents). See "hg
    help merge-tools" for information on configuring merge tools.

    The resolve command can be used in the following ways:

    - "hg resolve [--tool TOOL] FILE...": attempt to re-merge the specified
      files, discarding any previous merge attempts. Re-merging is not
      performed for files already marked as resolved. Use "--all/-a" to select
      all unresolved files. "--tool" can be used to specify the merge tool
      used for the given files. It overrides the HGMERGE environment variable
      and your configuration files.  Previous file contents are saved with a
      ".orig" suffix.
    - "hg resolve -m [FILE]": mark a file as having been resolved (e.g. after
      having manually fixed-up the files). The default is to mark all
      unresolved files.
    - "hg resolve -u [FILE]...": mark a file as unresolved. The default is to
      mark all resolved files.
    - "hg resolve -l": list files which had or still have conflicts. In the
      printed list, "U" = unresolved and "R" = resolved.

    Note that Mercurial will not let you commit files with unresolved merge
    conflicts. You must use "hg resolve -m ..." before you can commit after a
    conflicting merge.

    Returns 0 on success, 1 if any files fail a resolve attempt.
