- A link is a directory entry referring to a file; the same
- file (together with its size, all its protection informa-
- tion, etc.) may have several links to it. There are three
- kinds of links: hard links, symbolic links, and remote
- links.
-
- By default _l_n makes hard links. A hard link to a file is
- indistinguishable from the original directory entry; any
- changes to a file are effective independent of the name used
- to reference the file. Hard links may not refer to direc-
- tories (unless the proper incantations are supplied) and may
- not span file systems.
-
- The --ss option causes _l_n to create symbolic links. A sym-
- bolic link contains the name of the file to which it is
- linked. The referenced file is used when an _o_p_e_n(2) opera-
- tion is performed on the link. A _s_t_a_t(2) on a symbolic link
- will return the linked-to file; an _l_s_t_a_t(2) must be done to
- obtain information about the link. The _r_e_a_d_l_i_n_k(2) call may
- be used to read the contents of a symbolic link. Symbolic
- links may span file systems and may refer to directories.
-
- Given one or two arguments, _l_n creates a link to an existing
- file _s_o_u_r_c_e_n_a_m_e. If _t_a_r_g_e_t_n_a_m_e is given, the link has that
- name; _t_a_r_g_e_t_n_a_m_e may also be a directory in which to place
- the link; otherwise it is placed in the current directory.
- If only the directory is specified, the link will be made to
- the last component of _s_o_u_r_c_e_n_a_m_e.
-
- Given more than two arguments, _l_n makes links in _t_a_r_g_e_t_-
- _d_i_r_e_c_t_o_r_y to all the named source files. The links made
- will have the same name as the files being linked to.
-
- The --rr option causes _l_n to create remote links at the given
- location. Remote links are special files that identify
- places in Sprite where file system domains are attached to
- their parent domains. The source of a remote link must be
- an absolute path. In the normal case the source and target
- should be the same, ie. "ln -r /foo /foo".
