ln [options] file1 file2
ln [options] files directory

Create pseudonyms (links) for files, allowing them to be accessed by different names. In the first form, link file1 to file2, where file2 is usually a new filename. If file2 is an existing file, it is overwritten; if file2 is an existing directory, a link named file1 is created in that directory. In the second form, create links in directory, each link having the same name as the file specified.



Force the link to occur (don't prompt for overwrite permission).


Do not overwrite existing files.


Create a symbolic link. This lets you link across file systems and also see the name of the link when you run ls -l (otherwise there's no way to know the name that a file is linked to).
