## Move the file @var{f1} to the destination @var{f2}.
##
## The name @var{f1} may contain globbing patterns. If @var{f1} expands to
## multiple file names, @var{f2} must be a directory. If no destination
## @var{f2} is specified then the destination is the present working directory.
## If @var{f2} is a file name then @var{f1} is renamed to @var{f2}.
## When the force flag @qcode{'f'} is given any existing files will be
## overwritten without prompting.
##
## If successful, @var{status} is 1, and @var{msg}, @var{msgid} are empty
## character strings (""). Otherwise, @var{status} is 0, @var{msg} contains a
## system-dependent error message, and @var{msgid} contains a unique message
## identifier. Note that the status code is exactly opposite that of the
## @code{system} command.
