Getting Information on a File

    

The stat function gets a host of information about a file: 

($dev, $inode, $mode, $nlink, $uid, $gid, $rdev, $size, $atime,$mtime, $ctime, $blksize, $blocks) = stat(file);

The file can be either a file handle referring to a file you've opened or a file name. 
The stat function returns a list. 
The values returned from the stat function are listed in the following table.
The time values are returned as seconds from January 1, 1970.
If you don't have permission to read the file, lstat and stat will return an empty list.
