   1-b::
   2        Show blank SHA-1 for boundary commits.  This can also
   3        be controlled via the `blame.blankboundary` config option.
   4
   5--root::
   6        Do not treat root commits as boundaries.  This can also be
   7        controlled via the `blame.showroot` config option.
   8
   9--show-stats::
  10        Include additional statistics at the end of blame output.
  11
  12-L <start>,<end>::
  13-L :<regex>::
  14        Annotate only the given line range. May be specified multiple times.
  15        Overlapping ranges are allowed.
  16+
  17<start> and <end> are optional. ``-L <start>'' or ``-L <start>,'' spans from
  18<start> to end of file. ``-L ,<end>'' spans from start of file to <end>.

  21
  22-l::
  23        Show long rev (Default: off).
  24
  25-t::
  26        Show raw timestamp (Default: off).
  27
  28-S <revs-file>::
  29        Use revisions from revs-file instead of calling linkgit:git-rev-list[1].
  30
  31--reverse::
  32        Walk history forward instead of backward. Instead of showing
  33        the revision in which a line appeared, this shows the last
  34        revision in which a line has existed. This requires a range of
  35        revision like START..END where the path to blame exists in
  36        START.
  37
  38-p::
  39--porcelain::
  40        Show in a format designed for machine consumption.
  41
  42--line-porcelain::
  43        Show the porcelain format, but output commit information for
  44        each line, not just the first time a commit is referenced.
  45        Implies --porcelain.
  46
  47--incremental::
  48        Show the result incrementally in a format designed for
  49        machine consumption.
  50
  51--encoding=<encoding>::
  52        Specifies the encoding used to output author names
  53        and commit summaries. Setting it to `none` makes blame
  54        output unconverted data. For more information see the
  55        discussion about encoding in the linkgit:git-log[1]
  56        manual page.
  57
  58--contents <file>::
  59        When <rev> is not specified, the command annotates the
  60        changes starting backwards from the working tree copy.
  61        This flag makes the command pretend as if the working
  62        tree copy has the contents of the named file (specify
  63        `-` to make the command read from the standard input).
  64
  65--date <format>::
  66        The value is one of the following alternatives:
  67        {relative,local,default,iso,rfc,short}. If --date is not
  68        provided, the value of the blame.date config variable is
  69        used. If the blame.date config variable is also not set, the
  70        iso format is used. For more information, See the discussion
  71        of the --date option at linkgit:git-log[1].
  72
  73-M|<num>|::
  74        Detect moved or copied lines within a file. When a commit
  75        moves or copies a block of lines (e.g. the original file
  76        has A and then B, and the commit changes it to B and then
  77        A), the traditional 'blame' algorithm notices only half of
  78        the movement and typically blames the lines that were moved
  79        up (i.e. B) to the parent and assigns blame to the lines that
  80        were moved down (i.e. A) to the child commit.  With this
  81        option, both groups of lines are blamed on the parent by
  82        running extra passes of inspection.
  83+
  84<num> is optional but it is the lower bound on the number of
  85alphanumeric characters that Git must detect as moving/copying
  86within a file for it to associate those lines with the parent
  87commit. The default value is 20.
  88
  89-C|<num>|::
  90        In addition to `-M`, detect lines moved or copied from other
  91        files that were modified in the same commit.  This is
  92        useful when you reorganize your program and move code
  93        around across files.  When this option is given twice,
  94        the command additionally looks for copies from other
  95        files in the commit that creates the file. When this
  96        option is given three times, the command additionally
  97        looks for copies from other files in any commit.
  98+
  99<num> is optional but it is the lower bound on the number of
 100alphanumeric characters that Git must detect as moving/copying
 101between files for it to associate those lines with the parent
 102commit. And the default value is 40. If there are more than one
 103`-C` options given, the <num> argument of the last `-C` will
 104take effect.
