ln
LN(1) BSD General Commands Manual LN(1)NAME
ln -- make links
SYNOPSIS
ln [-fhinsv] source_file [target_file]
ln [-fhinsv] source_file ... target_dir
DESCRIPTION
The ln utility creates a new directory entry (linked file) which has the same modes as the original file. It is useful for maintaining mul-
tiple copies of a file in many places at once without using up storage for the ``copies''; instead, a link ``points'' to the original copy.
There are two types of links: hard links and symbolic links. How a link ``points'' to a file is one of the differences between a hard or
symbolic link.
The options are as follows:
-f Unlink any already existing file, permitting the link to occur.
-h If the target_file or target_dir is a symbolic link, do not follow it. This is most useful with the -f option, to replace a symlink
which may point to a directory.
-i Cause ln to write a prompt to standard error if the target file exists. If the response from the standard input begins with the char-
acter 'y' or 'Y', then unlink the target file so that the link may occur. Otherwise, do not attempt the link. (The -i option over-
rides any previous -f options.)
-n Same as -h, for compatibility with other ln implementations, namely GNU coreutils.
-s Create a symbolic link.
-v Cause ln to be verbose, showing files as they are processed.
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 normally refer to directories and may not span file sys-
tems.
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 source_file. If target_file is given, the link has that name; target_file
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 source_file.
Given more than two arguments, ln makes links in target_dir to all the named source files. The links made will have the same name as the
files being linked to.

The ln utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
The -v option is an extension to IEEE Std 1003.2-1992 (``POSIX.2'').
