last modified the line. Optionally, start annotating from the given revision.</p>

|
</div>
|

|
<div class="paragraph">
|

<p>When specified one or more times, <code>-L</code> restricts annotation to the requested

|

<div class="paragraph">
|
||
|
<p>The origin of lines is automatically followed across whole-file
|
||
|
renames (currently there is no option to turn the rename-following
|
||
|
off). To follow lines moved from one file to another, or to follow
|
||
|
lines that were copied and pasted from another file, etc., see the
|
||
|
<code>-C</code> and <code>-M</code> options.</p>

</div>

<div class="paragraph">
|
||
|
<p>The report does not tell you anything about lines which have been deleted or
|

replaced; you need to use a tool such as <em>git diff</em> or the "pickaxe"
|
||
|
interface briefly mentioned in the following paragraph.</p>

</div>
|
||
|
<div class="paragraph">
|
||
|
<p>Apart from supporting file annotation, Git also supports searching the
|
||
|
development history for when a code snippet occurred in a change. This makes it
|
||
|
possible to track when a code snippet was added to a file, moved or copied
|
||
|
between files, and eventually deleted or replaced. It works by searching for
|
||
|
a text string in the diff. A small example of the pickaxe interface
|

that searches for <code>blame_usage</code>:</p>

<p>Detect moved or copied lines within a file. When a commit
|
||
|
moves or copies a block of lines (e.g. the original file
|
||
|
has A and then B, and the commit changes it to B and then
|
||
|
A), the traditional <em>blame</em> algorithm notices only half of
|
||
|
the movement and typically blames the lines that were moved
|
||
|
up (i.e. B) to the parent and assigns blame to the lines that
|
||
|
were moved down (i.e. A) to the child commit. With this
|
||
|
option, both groups of lines are blamed on the parent by
|
||
|
running extra passes of inspection.</p>

<div class="paragraph">

useful when you reorganize your program and move code

around across files. When this option is given twice,

the command additionally looks for copies from other

<p>When you are not interested in changes older than version

range specifiers similar to <em>git rev-list</em>:</p>

<p>When revision range specifiers are used to limit the annotation,

lines that have not changed since the range boundary (either the

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