Name

ln

Synopsis

                  ln [options] sourcename [destname]
ln [options] sourcenames destdirectory
               

Create pseudonyms (links) for files, allowing them to be accessed by different names. The first form links sourcename to destname, where destname is usually either a new filename or (by default) a file in the current directory with the same name as sourcename. If destname is an existing file, it is overwritten; if destname is an existing directory, a link named sourcename is created in that directory. The second form creates links in destdirectory, each link having the same name as the file specified.

Options

-b, --backup=[control]

none, off

Never make backups.

numbered, t

Make numbered backups.

existing, nil

Match existing backups, numbered or simple.

simple, never

-d, -F, --directory

-f, --force

--help

Print a help message and then exit.

-i, --interactive

Prompt for permission before removing files.

Replace symbolic links to directories instead of dereferencing them. --force is useful with this option.

-s, --symbolic

Create a symbolic link. This lets you link ...
