 464 <div class="sectionbody">
 465 <div class="paragraph">
 466 <p>Annotates each line in the given file with information from the revision which
 467 last modified the line. Optionally, start annotating from the given revision.</p>
 468 </div>
 469 <div class="paragraph">
 470 <p>When specified one or more times, <code>-L</code> restricts annotation to the requested
 471 lines.</p>
 472 </div>
 473 <div class="paragraph">
 474 <p>The origin of lines is automatically followed across whole-file
 475 renames (currently there is no option to turn the rename-following
 476 off). To follow lines moved from one file to another, or to follow
 477 lines that were copied and pasted from another file, etc., see the
 478 <code>-C</code> and <code>-M</code> options.</p>
 479 </div>
 480 <div class="paragraph">
 481 <p>The report does not tell you anything about lines which have been deleted or
 482 replaced; you need to use a tool such as <em>git diff</em> or the "pickaxe"
 483 interface briefly mentioned in the following paragraph.</p>
 484 </div>
 485 <div class="paragraph">
 486 <p>Apart from supporting file annotation, Git also supports searching the
 487 development history for when a code snippet occurred in a change. This makes it
 488 possible to track when a code snippet was added to a file, moved or copied
 489 between files, and eventually deleted or replaced. It works by searching for
 490 a text string in the diff. A small example of the pickaxe interface
 491 that searches for <code>blame_usage</code>:</p>

 875 <p>Unlike <em>git blame</em> and <em>git annotate</em> in older versions of git, the extent
 876 of the annotation can be limited to both line ranges and revision
 877 ranges. The <code>-L</code> option, which limits annotation to a range of lines, may be
 878 specified multiple times.</p>
 879 </div>
 880 <div class="paragraph">
 881 <p>When you are interested in finding the origin for
 882 lines 40-60 for file <code>foo</code>, you can use the <code>-L</code> option like so

 889 git blame -L 40,+21 foo</pre>

 892 <div class="paragraph">

 895 <div class="literalblock">
 896 <div class="content">
 897 <pre>git blame -L '/^sub hello {/,/^}$/' foo</pre>
 898 </div>

 900 <div class="paragraph">
 901 <p>which limits the annotation to the body of the <code>hello</code> subroutine.</p>
 902 </div>
 903 <div class="paragraph">
 904 <p>When you are not interested in changes older than version
 905 v2.6.18, or changes older than 3 weeks, you can use revision
 906 range specifiers similar to <em>git rev-list</em>:</p>
 907 </div>
 908 <div class="literalblock">
 909 <div class="content">
 910 <pre>git blame v2.6.18.. -- foo

 915 <p>When revision range specifiers are used to limit the annotation,
 916 lines that have not changed since the range boundary (either the
 917 commit v2.6.18 or the most recent commit that is more than 3
 918 weeks old in the above example) are blamed for that range
 919 boundary commit.</p>

 922 <p>A particularly useful way is to see if an added file has lines
