    ln existingFile newFile

Run "man ln" to see the manual entry for "ln".

The meaning of the "-s" option is not well explained in the manuals.
"ln -s" is the only way to link files on different filesystems, but
newFile is only a pointer to existingFile, so if you delete existingFile
you won't be able to see it via the newFile pointer:

    $ echo hi >file1
    $ ln file1 file2   
    $ ln -s file1 file3
    $ ls -l file*
    -rw-rw-r--   2 jamesc   jamesc          3 Jan 12 19:46 file1
    -rw-rw-r--   2 jamesc   jamesc          3 Jan 12 19:46 file2
    lrwxrwxrwx   1 jamesc   jamesc          5 Jan 12 19:47 file3 -> file1
    $ cat file1
    hi
    $ cat file2
    hi
    $ cat file3
    hi
    $ rm file1
    $ ls -l file*
    -rw-rw-r--   1 jamesc   jamesc          3 Jan 12 19:46 file2
    lrwxrwxrwx   1 jamesc   jamesc          5 Jan 12 19:47 file3 -> file1
    $ cat file1
    cat: file1: No such file or directory
    $ cat file2
    hi
    $ cat file3
    cat: file3: No such file or directory

That last one is a bit unintuitive, because the pointer is still there,
but what it points to is not still there so it gives an error.
