You could create another softlinkB within directoryA, then you could access directoryB via softlinkA/softlinkB. Or is this not what you wanted? The description of softlinkC is confusing. Perhaps you need to provide an example with full directory paths, exact locations of each softlink, and what the desired paths are.
Thanks Peter, I wanted to create a softlink under a softlink. In fact this no different to creating a softlink under a directory.
What I did was created the softlink, I then cd to that softlink, an then created my second softlink under the first.
simple an logical should have thought of that straight away.
