stat.dev_minor â fixnum Instance Public methods Returns the minor part of File_Stat#dev or nil. File.stat("/dev/fd1").dev_minor #=> 1 File.stat("/dev/tty").dev_minor #=> 0

stat.dev_major â fixnum Instance Public methods Returns the major part of File_Stat#dev or nil. File.stat("/dev/fd1").dev_major #=> 2 File.stat("/dev/tty").dev_major #=> 5

stat.dev â fixnum Instance Public methods Returns an integer representing the device on which stat resides. File.stat("testfile").dev #=> 774

stat.ctime â aTime Instance Public methods Returns the change time for stat (that is, the time directory information about the file was changed, not the file itself). Note that on Windows (NTFS), returns creation time (birth time). File.stat("testfile").ctime #=> Wed Apr 09 08:53:14 CDT 2003

stat.blocks â integer or nil Instance Public methods Returns the number of native file system blocks allocated for this file, or nil if the operating system doesn't support this feature. File.stat("testfile").blocks #=> 2

stat.blockdev? â true or false Instance Public methods Returns true if the file is a block device, false if it isn't or if the operating system doesn't support this feature. File.stat("testfile").blockdev? #=> false File.stat("/dev/hda1").blockdev? #=> true
