I've tried:

In[169]:= newton3[x_] := N[1/2 (x + 3/x)];
FixedPointList[newton3, 1.0]

Out[170]= {1., 2., 1.75, 1.73214, 1.73205, 1.73205, 1.73205}


Of course:

In[164]:= N[Sqrt[3], 20]

Out[164]= 1.7320508075688772935


How do you use the FixedPointList to increase the number of decimal places?


Question: Redhat: non-root user needs to copy files to a NFS share
Answer: I'm going to assume that the server is configured to only allow this particular client to connect.  Otherwise you could use a client where you did have root access.  (How the server identifies this client is something worth questioning too, in a pinch.)

If you must use NFS and don't have root access on the client, then my first thought is to find a userspace NFS client or NFS browser.  The only one I've found so far is JFtp, which is a Java GUI client.  However, if you're a programmer and so inclined, another option is to roll your own; there is a library called libnfs1 that you could build from.

I haven't tried either of them, but hopefully this is a start.  There may be more out there that I haven't noticed.  Finally, beware that the NFS server may require you to connect as root (from a privileged port), in which case you're out of luck.

...Alternately, I just noticed your '//somebox/somefolder/' nomenclature, which is highly unusual for NFS, but standard for SMB (Samba / Windows filesharing), at least on Linux machines.  If that's the case, then the tool you want is smbclient.
