Instead of the content, show the object type identified by <object>.

Instead of the content, show the object size identified by <object>. If used with --use-mailmap option, will show the size of updated object after replacing idents using the mailmap mechanism.

Exit with zero status if <object> exists and is a valid object. If <object> is of an invalid format, exit with non-zero status and emit an error on stderr.

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

Show the content as transformed by a textconv filter. In this case, <object> has to be of the form <tree-ish>:<path>, or :<path> in order to apply the filter to the content recorded in the index at <path>.

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

For use with --textconv or --filters, to allow specifying an object name and a path separately, e.g. when it is difficult to figure out the revision from which the blob came.

Print object information and contents for each object provided on stdin. May not be combined with any other options or arguments except --textconv, --filters, or --use-mailmap. •When used with --textconv or --filters, the input lines must specify the path, separated by whitespace. See the section BATCH OUTPUT below for details. •When used with --use-mailmap, for commit and tag objects, the contents part of the output shows the identities replaced using the mailmap mechanism, while the information part of the output shows the size of the object as if it actually recorded the replacement identit

Enter a command mode that reads commands and arguments from stdin. May only be combined with --buffer, --textconv, --use-mailmap or --filters. •When used with --textconv or --filters, the input lines must specify the path, separated by whitespace. See the section BATCH OUTPUT below for details. •When used with --use-mailmap, for commit and tag objects, the contents command shows the identities replaced using the mailmap mechanism, while the info command shows the size of the object as if it actually recorded the replacement identities. --batch-command recognizes the following commands: content

Instead of reading a list of objects on stdin, perform the requested batch operation on all objects in the repository and any alternate object stores (not just reachable objects). Requires --batch or --batch-check be specified. By default, the objects are visited in order sorted by their hashes; see also --unordered below. Objects are presented as-is, without respecting the "replace" mechanism of git-replace(1).

Normally batch output is flushed after each object is output, so that a process can interactively read and write from cat-file. With this option, the output uses normal stdio buffering; this is much more efficient when invoking --batch-check or --batch-command on a large number of objects.

When --batch-all-objects is in use, visit objects in an order which may be more efficient for accessing the object contents than hash order. The exact details of the order are unspecified, but if you do not require a specific order, this should generally result in faster output, especially with --batch. Note that cat-file will still show each object only once, even if it is stored multiple times in the repository.

Allow -s or -t to query broken/corrupt objects of unknown type.

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) b

Only meaningful with --batch, --batch-check, or --batch-command; input and output is NUL-delimited instead of newline-delimited.

Only meaningful with --batch, --batch-check, or --batch-command; input is NUL-delimited instead of newline-delimited. This option is deprecated in favor of -Z as the output can otherwise be ambiguous.
