<object>

<p>
The name of the object to show.
For a more complete list of ways to spell object names, see
the "SPECIFYING REVISIONS" section in <a href="gitrevisions.html">gitrevisions(7)</a>.
</p>
</dd>
<dt class="hdlist1">
-t
</dt>
<dd>
<p>
Instead of the content, show the object type identified by
<code><object></code>.
</p>
</dd>
<dt class="hdlist1">
-s
</dt>
<dd>
<p>
Instead of the content, show the object size identified by
<code><object></code>. If used with <code>--use-mailmap</code> option, will show
the size of updated object after replacing idents using the
mailmap mechanism.
</p>
</dd>
<dt class="hdlist1">
-e
</dt>
<dd>
<p>
Exit with zero status if <code><object></code> exists and is a valid
object. If <code><object></code> is of an invalid format, exit with non-zero
status and emit an error on stderr.
</p>
</dd>
<dt class="hdlist1">

<p>
Pretty-print the contents of <code><object></code> based on its type.

</dd>
<dt class="hdlist1">
<type>
</dt>
<dd>
<p>
Typically this matches the real type of <code><object></code> but asking
for a type that can trivially be dereferenced from the given
<code><object></code> is also permitted. An example is to ask for a
"tree" with <code><object></code> being a commit object that contains it,
or to ask for a "blob" with <code><object></code> being a tag object that
points at it.

<dt class="hdlist1">

See <a href="git-shortlog.html">git-shortlog(1)</a>.

</dd>
<dt class="hdlist1">

Show the content as transformed by a textconv filter. In this case,

order to apply the filter to the content recorded in the index at
<code><path></code>.

--filters
</dt>
<dd>
<p>
Show the content as converted by the filters configured in
the current working tree for the given <code><path></code> (i.e. smudge filters,
end-of-line conversion, etc). In this case, <code><object></code> has to be of
the form <code><tree-ish>:<path></code>, or <code>:<path></code>.
</p>
</dd>
<dt class="hdlist1">
--path=<path>
</dt>

the revision from which the blob came.
