Stat (Unix)

(Redirected from Rdev)

stat() is a Unix system call that returns useful data about an i-node. The semantics of stat() vary between Operating Systems. In the platform-independent scripting tool Perl, stat() returns a thirteen-element array. From the Perl documentation:

Not all fields are supported on all filesystem types.  Here are the
meaning of the fields:

 0 dev      device number of filesystem
 1 ino      inode number
 2 mode     file mode  (type and permissions)
 3 nlink    number of (hard) links to the file
 4 uid      numeric user ID of file's owner
 5 gid      numeric group ID of file's owner
 6 rdev     the device identifier (special files only)
 7 size     total size of file, in bytes
 8 atime    last access time in Unix time format
 9 mtime    last modify time in Unix time format
10 ctime    inode change time (NOT creation time!) in Unix time format
11 blksize  preferred block size for file system I/O
12 blocks   actual number of blocks allocated
