.B Note
that the shell expands wild card characters and performs input/output
redirections when the 
.B do-until
command is started, now then 
.B do-until
invokes the command it gets.
If this matters, you may need to invoke the command you need via
"sh -c 'foo > bar'" 
or some similar incantation.
See your shell manual for details.
