     uux [options] command

   The `uux' command is used to execute a command on a remote system,
or to execute a command on the local system using files from remote
systems.  The command is not executed immediately; the request is queued
until the `uucico' daemon calls the system and transfers the necessary
files.  The daemon is started automatically unless one of the `-r' or
`--nouucico' options is given.

   The actual command execution is done by the `uuxqt' daemon on the
appropriate system.

   File arguments can be gathered from remote systems to the execution
system, as can standard input.  Standard output may be directed to a
file on a remote system.

   The command name may be preceded by a system name followed by an
exclamation point if it is to be executed on a remote system.  An empty
system name is taken as the local system.

   Each argument that contains an exclamation point is treated as
naming a file.  The system which the file is on is before the
exclamation point, and the file name on that system follows it.  An
empty system name is taken as the local system; this form must be used
to transfer a file to a command being executed on a remote system.  If
the file name is not absolute, the current working directory will be
prepended to it; the result may not be meaningful on the remote system.
A file name may begin with `~/', in which case it is relative to the
UUCP public directory on the appropriate system.  A file name may begin
with `~name/', in which case it is relative to the home directory of the
named user on the appropriate system.

   Standard input and output may be redirected as usual; the file names
used may contain exclamation points to indicate that they are on remote
systems.  Note that the redirection characters must be quoted so that
they are passed to `uux' rather than interpreted by the shell.  Append
redirection (`>>') does not work.

   All specified files are gathered together into a single directory
before execution of the command begins.  This means that each file must
have a distinct name.  For example,
     uux 'sys1!diff sys2!~user1/foo sys3!~user2/foo >!foo.diff'
   will fail because both files will be copied to `sys1' and stored
under the name `foo'.

   Arguments may be quoted by parentheses to avoid interpretation of
exclamation points.  This is useful when executing the `uucp' command
on a remote system.

   Most systems restrict the commands which may be executed using
`uux'.  Many permit only the execution of `rmail' and `rnews'.

   A request to execute an empty command (e.g., `uux sys!') will create
a poll file for the specified system; see See Calling Other Systems
for an example of why this might be useful.
