ln Command

Creates a link to a file.

Syntax

ln [-f] [-n] [-s] existingfile newname

-fLink files without questioning the user, even if the mode of target forbids writing. This is the default if the standard input is not a terminal.
-nDoes not overwrite existing files.
-sMakes it so that it does not create a symbolic link (not on System V..) existingfile - The file that you want to create a new link.
existingfileSpecifies file(s) that you want to create a link to.
newnameThe new name of the file.
directoryThe directory were you want the new link.

Examples

ln public_html/myfile.txt

Would create a hard link to myfile.txt in the current directory assuming that it is not public_html. Note: A link cannot be created to a file if currently in the directory where the file exists.

ln -s file1 file2

Creates a Symbolic Link to file1 with the name of the file2.
