ln - make links
ln [ -s ] sourcename [ targetname ]
ln [ -s ] sourcename1 sourcename2 [ sourcename3 ... ] targetdirectory
A link is a directory entry referring to a file; the same file (together with its size,
all its protection information, etc.) 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 orig-
inal 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 directo-
The -s option causes ln to create symbolic links. A symbolic link contains the name of
the file to which it is linked. The referenced file is used when an open(2) operation is
performed on the link. A stat(2) on a symbolic link will return the linked-to file; an
lstat(2) must be done to obtain information about the link. The readlink(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, ln creates a link to an existing file sourcename. If target-
name is given, the link has that name; targetname 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 sourcename.
Given more than two arguments, ln makes links in targetdirectory to all the named source
files. The links made will have the same name as the files being linked to.
