LN(1) BSD LN(1)
NAME
ln - make links
SYNOPSIS
ln [ -s ] sourcename [ targetname ]
ln [ -s ] sourcename1 sourcename2 [ sourcename3 ... ] targetdirectory
DESCRIPTION
A link is a directory entry referring to a file; the same file (together
with its size, all its protection information,and so on) may have several
links to it. There are two kinds of links, hard links and symbolic
links.
By default ln 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 span file systems and may not refer to directories.
The -s option causes ln to create symbolic links. A symbolic link
contains the name of the file it is linked to. The referenced file is
used when an open(2) operation is performed on the link. A stat(2) on a
symbolic link returns the linked-to file; you must execute lstat(2) to
get information about the link. You can use the readlink(2) call to read
the contents of a symbolic link. Symbolic links may span file systems
and may refer to directories.
Given one or two arguments, ln creates a link to an existing file
sourcename. If targetname is given, the link has that name; targetname
can also be a directory in which to place the link; otherwise ln places
it in the current directory. If only the directory is specified, ln
makes the link to the last component of sourcename.
Given more than two arguments, ln makes links in targetdirectory to all
the named source files. The links made have the same name as the files
being linked to.
NOTE
Symbolic links in Domain/OS are implemented as soft links. These are
identical in behavior, except that soft links do not have protections
associated with the links themselves.
Domain/OS symbolic links are implemented in the parent directory object,
not in separate files. Because of this, symbolic links created in the
same directory will share the creation/modification information for the
most recently created symbolic link.
