|
|
<p>In its first form, the command provides the content or the type of an object in
|
|
the repository. The type is required unless <code>-t</code> or <code>-p</code> is used to find the
|
|
object type, or <code>-s</code> is used to find the object size, or <code>--textconv</code> or
|
|
<code>--filters</code> is used (which imply type "blob").</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>In the second form, a list of objects (separated by linefeeds) is provided on
|
|
stdin, and the SHA-1, type, and size of each object is printed on stdout. The
|
|
output format can be overridden using the optional <code><format></code> argument. If
|
|
either <code>--textconv</code> or <code>--filters</code> was specified, the input is expected to
|
|
list the object names followed by the path name, separated by a single
|
|
whitespace, so that the appropriate drivers can be determined.</p>

the linked-to object. If a symlink points outside the
