Display file or file system status. Mandatory arguments to long options are mandatory for short options too.

       stat [OPTION]... FILE...

    -L, --dereference
              follow links

    -f, --file-system
              display file system status instead of file status

    -c  --format=FORMAT
              use the specified FORMAT instead of the default; output a
              newline after each use of FORMAT

              like --format, but interpret backslash escapes, and do not
              output a mandatory trailing newline; if you want a newline,
              include \n in FORMAT

    -t, --terse
              print the information in terse form

    --help display this help and exit

              output version information and exit

The valid format sequences for files (without --file-system):

    %a     Access rights in octal
    %A     Access rights in human readable form

    %G     Group name of owner
    %h     Number of hard links

    %o     Optimal I/O transfer size hint
    %s     Total size, in bytes
    %t     Major device type in hex, for character/block device special files
    %T     Minor device type in hex, for character/block device special files

    %Y     Time of last data modification, seconds since Epoch
    %z     Time of last status change, human-readable

    %a     Free blocks available to non-superuser
    %b     Total data blocks in file system
    %c     Total file nodes in file system
    %d     Free file nodes in file system
    %f     Free blocks in file system
    %i     File system ID in hex
    %l     Maximum length of filenames
    %n     File name
    %s     Block size (for faster transfers)
    %S     Fundamental block size (for block counts)
    %t     File system type in hex
    %T     File system type in human readable form

Your shell can have its own version of stat, which usually supersedes the version described here. Please refer to your shell’s documentation for details about the options it supports.
