Yes, this would work, as long as the source and destination architecture
are compatible (i.e., same endian flavour: linux, alpha, axlinux, sol86;
or sol, sul, ibm, hp, hp2, sgi; but not a mixture of these two sets).

Basically, you figure out the userid in "extended hex":

  bash$ EHEX 370
  AA
  bash$ 

(EHEX is in $SYSUNIX, which is in your path if you've sourced the LOGIN.SH
or LOGIN.CSH file).  This tells me that my AIPS userid is 0AA in extended
hex (base 36).  I can then cd to a data area and see all my files:

  bash$ cd /DATA/ORANGUTAN_1
  bash$ ls *.0AA\;

  bash$ 

If I wanted to move these to another machine via NFS:

  bash$ ls /DATA/OTHERSYSTEM_1/*.0AA\;
  ls: /DATA/OTHERSYSTEM_1/*.0AA;: No such file or directory
  bash$

Good; I don't have any files there.  So let's copy (remember, I'm still in
the first data area):

  bash$ cp *.0AA\; /DATA/OTHERSYSTEM_1/

That's it.  The data are now in both areas.  You can do a similar copy via
scp if the data area is not NFS mounted, e.g.

        scp *.0AA\; othersystem.uchicago.edu:/wherever/DATA_1/

Hope this helps.
