Well, "file" is the well-known established word, it is just linux that
forces you to use ls/readdir() instead of cat/read() on directories
which works for other unices (at least used to work, I havn't checked
reasently).

What do you want to use it for ?

              File is of type c:
              b      block (buffered) special
              c      character (unbuffered) special

              l      symbolic link; this is never true if the -L option or the
                     -follow  option is in effect, unless the symbolic link is
                     broken.  If you want to search for symbolic links when -L
                     is in effect, use -xtype.
