Stat (S)

A Stat is a collection of attributes associated with an Inode--or, from the user's point of view, a virtual file.

The following have their usual POSIX or Unix meanings:

• gid (numeric)
• link count (this may not be physically stored, but implied by other data)
• mtime, atime, ctime
• uid (numeric)
• mode (only the portable bits: $07777$)
• size (in bytes, 64 bits)
• type (file, directory, pipe, socket, character, block, or symlink)
• major, minor (for device special files only)
• target name (for symlink special files only)

In addition, a Stat contains the following attribute:

• hash (Hash of contents of the file, if it is non-zero size)
