What does filestat function modeoct value mean?

[craigcomstock]

I was confused about this modeoct return value for the filestat command returning 6-digit octal values, seemingly always prefixing the normal 4-digit values with '10'.

After some research I found in man inode(7) that this '10' prefix as it were indicates "regular file"

       The following mask values are defined for the file type:

           S_IFMT     0170000   bit mask for the file type bit field

           S_IFSOCK   0140000   socket
           S_IFLNK    0120000   symbolic link
           S_IFREG    0100000   regular file
           S_IFBLK    0060000   block device
           S_IFDIR    0040000   directory
           S_IFCHR    0020000   character device
           S_IFIFO    0010000   FIFO
