Documentation / diff-options.txton commit git-svn: bugfix and optimize the 'log' command (c0d4822)
   1-p::
   2        Generate patch (see section on generating patches)
   3
   4-u::
   5        Synonym for "-p".
   6
   7--patch-with-raw::
   8        Generate patch but keep also the default raw diff output.
   9
  10--stat::
  11        Generate a diffstat instead of a patch.
  12
  13--summary::
  14        Output a condensed summary of extended header information
  15        such as creations, renames and mode changes.
  16
  17--patch-with-stat::
  18        Generate patch and prepend its diffstat.
  19
  20-z::
  21        \0 line termination on output
  22
  23--name-only::
  24        Show only names of changed files.
  25
  26--name-status::
  27        Show only names and status of changed files.
  28
  29--full-index::
  30        Instead of the first handful characters, show full
  31        object name of pre- and post-image blob on the "index"
  32        line when generating a patch format output.     
  33
  34--abbrev[=<n>]::
  35        Instead of showing the full 40-byte hexadecimal object
  36        name in diff-raw format output and diff-tree header
  37        lines, show only handful hexdigits prefix.  This is
  38        independent of --full-index option above, which controls
  39        the diff-patch output format.  Non default number of
  40        digits can be specified with --abbrev=<n>.
  41
  42-B::
  43        Break complete rewrite changes into pairs of delete and create.
  44
  45-M::
  46        Detect renames.
  47
  48-C::
  49        Detect copies as well as renames.
  50
  51--diff-filter=[ACDMRTUXB*]::
  52        Select only files that are Added (`A`), Copied (`C`),
  53        Deleted (`D`), Modified (`M`), Renamed (`R`), have their
  54        type (mode) changed (`T`), are Unmerged (`U`), are
  55        Unknown (`X`), or have had their pairing Broken (`B`).
  56        Any combination of the filter characters may be used.
  57        When `*` (All-or-none) is added to the combination, all
  58        paths are selected if there is any file that matches
  59        other criteria in the comparison; if there is no file
  60        that matches other criteria, nothing is selected.
  61
  62--find-copies-harder::
  63        For performance reasons, by default, -C option finds copies only 
  64        if the original file of the copy was modified in the same 
  65        changeset.  This flag makes the command
  66        inspect unmodified files as candidates for the source of
  67        copy.  This is a very expensive operation for large
  68        projects, so use it with caution.
  69
  70-l<num>::
  71        -M and -C options require O(n^2) processing time where n
  72        is the number of potential rename/copy targets.  This
  73        option prevents rename/copy detection from running if
  74        the number of rename/copy targets exceeds the specified
  75        number.
  76
  77-S<string>::
  78        Look for differences that contain the change in <string>.
  79
  80--pickaxe-all::
  81        When -S finds a change, show all the changes in that
  82        changeset, not just the files that contain the change
  83        in <string>.
  84
  85--pickaxe-regex::
  86        Make the <string> not a plain string but an extended POSIX
  87        regex to match.
  88
  89-O<orderfile>::
  90        Output the patch in the order specified in the
  91        <orderfile>, which has one shell glob pattern per line.
  92
  93-R::
  94        Swap two inputs; that is, show differences from index or
  95        on-disk file to tree contents.
