- 'git cat-file' (--batch | --batch-check) < <list-of-objects>
+ 'git cat-file' (--batch | --batch-check) [--follow-symlinks] < <list-of-objects>
DESCRIPTION
-----------
not be combined with any other options or arguments. See the
section `BATCH OUTPUT` below for details.
+--allow-unknown-type::
+ Allow -s or -t to query broken/corrupt objects of unknown type.
+
+ --follow-symlinks::
+ With --batch or --batch-check, follow symlinks inside the
+ repository when requesting objects with extended SHA-1
+ expressions of the form tree-ish:path-in-tree. Instead of
+ providing output about the link itself, provide output about
+ the linked-to object. If a symlink points outside the
+ tree-ish (e.g. a link to /foo or a root-level link to ../foo),
+ the portion of the link which is outside the tree will be
+ printed.
+ +
+ This option does not (currently) work correctly when an object in the
+ index is specified (e.g. `:link` instead of `HEAD:link`) rather than
+ one in the tree.
+ +
+ This option cannot (currently) be used unless `--batch` or
+ `--batch-check` is used.
+ +
+ For example, consider a git repository containing:
+ +
+ --
+ f: a file containing "hello\n"
+ link: a symlink to f
+ dir/link: a symlink to ../f
+ plink: a symlink to ../f
+ alink: a symlink to /etc/passwd
+ --
+ +
+ For a regular file `f`, `echo HEAD:f | git cat-file --batch` would print
+ +
+ --
+ ce013625030ba8dba906f756967f9e9ca394464a blob 6
+ --
+ +
+ And `echo HEAD:link | git cat-file --batch --follow-symlinks` would
+ print the same thing, as would `HEAD:dir/link`, as they both point at
+ `HEAD:f`.
+ +
+ Without `--follow-symlinks`, these would print data about the symlink
+ itself. In the case of `HEAD:link`, you would see
+ +
+ --
+ 4d1ae35ba2c8ec712fa2a379db44ad639ca277bd blob 1
+ --
+ +
+ Both `plink` and `alink` point outside the tree, so they would
+ respectively print:
+ +
+ --
+ symlink 4
+ ../f
+
+ symlink 11
+ /etc/passwd
+ --
+
+
OUTPUT
------
If '-t' is specified, one of the <type>.
<object> SP missing LF
------------
+ If --follow-symlinks is used, and a symlink in the repository points
+ outside the repository, then `cat-file` will ignore any custom format
+ and print:
+
+ ------------
+ symlink SP <size> LF
+ <symlink> LF
+ ------------
+
+ The symlink will either be absolute (beginning with a /), or relative
+ to the tree root. For instance, if dir/link points to ../../foo, then
+ <symlink> will be ../foo. <size> is the size of the symlink in bytes.
+
+ If --follow-symlinks is used, the following error messages will be
+ displayed:
+
+ ------------
+ <object> SP missing LF
+ ------------
+ is printed when the initial symlink requested does not exist.
+
+ ------------
+ dangling SP <size> LF
+ <object> LF
+ ------------
+ is printed when the initial symlink exists, but something that
+ it (transitive-of) points to does not.
+
+ ------------
+ loop SP <size> LF
+ <object> LF
+ ------------
+ is printed for symlink loops (or any symlinks that
+ require more than 40 link resolutions to resolve).
+
+ ------------
+ notdir SP <size> LF
+ <object> LF
+ ------------
+ is printed when, during symlink resolution, a file is used as a
+ directory name.
