git-cat-file - Provide content or type information for repository objects
git-cat-file [-t | -s | -e | -p | <type>] <object>
Provides content or type of objects 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.
The sha1 identifier of the object.
Instead of the content, show the object type identified by <object>.
Instead of the content, show the object size identified by <object>.
Suppress all output; instead exit with zero status if <object> exists and is a valid object.
Pretty-print the contents of <object> based on its 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.
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.
Otherwise the raw (though uncompressed) contents of the <object> will be returned.
