Documentation / blame-options.txton commit Emit a whole line in one go (2efcc97)
   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        Annotate only the given line range.  <start> and <end> can take
  14        one of these forms:
  15
  16        - number
  17+
  18If <start> or <end> is a number, it specifies an
  19absolute line number (lines count from 1).
  20+
  21
  22- /regex/
  23+
  24This form will use the first line matching the given
  25POSIX regex.  If <end> is a regex, it will search
  26starting at the line given by <start>.
  27+
  28
  29- +offset or -offset
  30+
  31This is only valid for <end> and will specify a number
  32of lines before or after the line given by <start>.
  33+
  34
  35-l::
  36        Show long rev (Default: off).
  37
  38-t::
  39        Show raw timestamp (Default: off).
  40
  41-S <revs-file>::
  42        Use revisions from revs-file instead of calling linkgit:git-rev-list[1].
  43
  44--reverse::
  45        Walk history forward instead of backward. Instead of showing
  46        the revision in which a line appeared, this shows the last
  47        revision in which a line has existed. This requires a range of
  48        revision like START..END where the path to blame exists in
  49        START.
  50
  51-p::
  52--porcelain::
  53        Show in a format designed for machine consumption.
  54
  55--incremental::
  56        Show the result incrementally in a format designed for
  57        machine consumption.
  58
  59--encoding=<encoding>::
  60        Specifies the encoding used to output author names
  61        and commit summaries. Setting it to `none` makes blame
  62        output unconverted data. For more information see the
  63        discussion about encoding in the linkgit:git-log[1]
  64        manual page.
  65
  66--contents <file>::
  67        When <rev> is not specified, the command annotates the
  68        changes starting backwards from the working tree copy.
  69        This flag makes the command pretend as if the working
  70        tree copy has the contents of the named file (specify
  71        `-` to make the command read from the standard input).
  72
  73--date <format>::
  74        The value is one of the following alternatives:
  75        {relative,local,default,iso,rfc,short}. If --date is not
  76        provided, the value of the blame.date config variable is
  77        used. If the blame.date config variable is also not set, the
  78        iso format is used. For more information, See the discussion
  79        of the --date option at linkgit:git-log[1].
  80
  81-M|<num>|::
  82        Detect moved or copied lines within a file. When a commit
  83        moves or copies a block of lines (e.g. the original file
  84        has A and then B, and the commit changes it to B and then
  85        A), the traditional 'blame' algorithm notices only half of
  86        the movement and typically blames the lines that were moved
  87        up (i.e. B) to the parent and assigns blame to the lines that
  88        were moved down (i.e. A) to the child commit.  With this
  89        option, both groups of lines are blamed on the parent by
  90        running extra passes of inspection.
  91+
  92<num> is optional but it is the lower bound on the number of
  93alphanumeric characters that git must detect as moving/copying
  94within a file for it to associate those lines with the parent
  95commit. The default value is 20.
  96
  97-C|<num>|::
  98        In addition to `-M`, detect lines moved or copied from other
  99        files that were modified in the same commit.  This is
 100        useful when you reorganize your program and move code
 101        around across files.  When this option is given twice,
 102        the command additionally looks for copies from other
 103        files in the commit that creates the file. When this
 104        option is given three times, the command additionally
 105        looks for copies from other files in any commit.
 106+
 107<num> is optional but it is the lower bound on the number of
 108alphanumeric characters that git must detect as moving/copying
 109between files for it to associate those lines with the parent
 110commit. And the default value is 40. If there are more than one
 111`-C` options given, the <num> argument of the last `-C` will
 112take effect.
 113
 114-h::
 115--help::
 116        Show help message.
