- <h3>Name</h3>
- ln - link files
- <h3>Synopsis</h3>
- /bin/ln <em>oldfile</em> <em>newfile</em>
- <br>
- /bin/ln -s <em>oldfile</em> <em>newfile</em>
- <h3>Description</h3>
- ln creates links to files. The first usage creates a hard link, that
- is, an additional name for the <strong>same</strong> file. The second
- usage, with the -s option, creates a symbolic link, a special
- filesystem entry that redirects accesses back to the first original
- file.
- <p>
- The symlink created is of the form <em>newfile</em> -> <em>oldfile</em>.
- <p>
- <h3>Requirements</h3>
- ln uses the following syscalls:
- <ul>
- <li><A HREF=../syscall/link.html>link</A>
- <li><A HREF=../syscall/symlink.html>symlink</A>
- <li><A HREF=../syscall/write.html>write</A>
- <li><A HREF=../syscall/_exit.html>_exit</A>
- </ul>
- ln without the -s option should work once (or if) you implement hard
- links. ln with the -s option should work once (or if) you implement
- symbolic links. Check your assignments for when (or if) you need to
- implement these features.
- <p>
- ln is able to create symlinks even if hard links are not implemented,
- and vice versa.
