files can be sorted on name and stat() attributes, ascending and descending:
name file name
dev device number
ino inode number
mode inode protection mode
nlink number of links
uid userid of owner
gid groupid of owner
rdev device type, if inode device *
size size in bytes
atime time of last access (Unix timestamp)
mtime time of last modification (Unix timestamp)
ctime time of last inode change (Unix timestamp)
blksize blocksize of filesystem IO *
blocks number of blocks allocated
