cat-file with an object on the command line requires an option to tell it what to output (type, size, pretty-print, etc). However, the square brackets in the usage imply that those options are not required. This patch switches them to parentheses to indicate "required but grouped-OR" (curly braces might also work, but this follows the convention used already by "git stash"). While we're at it, let's change the <sha1> specifier in the usage to <object>. That's what the documentation uses, and it does actually use the regular object lookup.

NAME
|
|
----
|
|
git-cat-file - Provide content or type and size information for repository objects
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git cat-file' (-t | -s | -e | -p | <type>) <object>
|
|
'git cat-file' (--batch | --batch-check) < <list-of-objects>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
In its first form, the command provides the content or the type of an object in
|
|
the repository. The type is required unless '-t' or '-p' is used to find the
|
|
object type, or '-s' is used to find the object size.
|
|
|
|
In the second form, a list of objects (separated by linefeeds) is provided on
|
|
stdin, and the SHA1, type, and size of each object is printed on stdout.
|
|
|
|
OPTIONS
|
|
-------
|
|
<object>::
|
|
The name of the object to show.
|
|
For a more complete list of ways to spell object names, see
|
|
the "SPECIFYING REVISIONS" section in linkgit:git-rev-parse[1].
|
|
|
|
-t::
|
|
Instead of the content, show the object type identified by
|
|
<object>.
|
|
|
|
-s::
|
|
Instead of the content, show the object size identified by
|
|
<object>.
|
|
|
|
-e::
|
|
Suppress all output; instead exit with zero status if <object>
|
|
exists and is a valid object.
|
|
|
|
-p::
|
|
Pretty-print the contents of <object> based on its type.
|
|
|
|
<type>::
|
|
Typically this matches the real type of <object> but asking
|
|
for a type that can trivially be dereferenced from the given
|
|
<object> is also permitted. An example is to ask for a
|
|
"tree" with <object> being a commit object that contains it,
|
|
or to ask for a "blob" with <object> being a tag object that
|
|
points at it.
|
|
|
|
--batch::
|
|
Print the SHA1, type, size, and contents of each object provided on
|
|
stdin. May not be combined with any other options or arguments.
|
|
|
|
--batch-check::
|
|
Print the SHA1, type, and size of each object provided on stdin. May not
|
|
be combined with any other options or arguments.
|
|
|
|
OUTPUT
|
|
------
|
|
If '-t' is specified, one of the <type>.
|
|
|
|
If '-s' is specified, the size of the <object> in bytes.
|
|
|
|
If '-e' is specified, no output.
|
|
|
|
If '-p' is specified, the contents of <object> are pretty-printed.
|
|
|
|
If <type> is specified, the raw (though uncompressed) contents of the <object>
|
|
will be returned.
|
|
|
|
If '--batch' is specified, output of the following form is printed for each
|
|
object specified on stdin:
|
|
|
|
------------
|
|
<sha1> SP <type> SP <size> LF
|
|
<contents> LF
|
|
------------
|
|
|
|
If '--batch-check' is specified, output of the following form is printed for
|
|
each object specified on stdin:
|
|
|
|
------------
|
|
<sha1> SP <type> SP <size> LF
|
|
------------
|
|
|
|
For both '--batch' and '--batch-check', output of the following form is printed
|
|
for each object specified on stdin that does not exist in the repository:
|
|
|
|
------------
|
|
<object> SP missing LF
|
|
------------
