SYNTAX
SYNTAX: uux [ - ] command-string
FUNCTION: uux gathers 0 or more files from various systems,
executes commands on a specified system, and sends the
standard output to a file on a specified system.
The command-string is made up of one or more arguments
that look like a shell command line, except that the
command and the filename may be prefixed by system-name!
A null system-name is interpreted as the local system.
NOTE: The - option causes the standard input to the uux
command to be the standard input to the command string.

uux is a part of the UUCP family of commands.
uux executes commands on remote UNIX systems.
For example, let's say you are on the system sys0 and
you need a particular capability or resource from the
system sys1. You can use this resource by issuing a
command that will be executed on the system sys1 while
asking for the results to be sent to your system, sys0.
The syntax for uux is shown above. The filenames used
by uux may be:
(1) full pathnames;
(2) a pathname preceded by ~xxx, where xxx is a user ID on the
specified system and is replaced by that user's login directory;
(3) anything else prefixed by the current directory.
You can use uux for printing reports on a high-quality
printer on another system; you can compare files from different
systems and send results to the local system; you can use
tape drives on another system for reading your tapes and
then transfer the files to your system, etc.
Assuming the situation shown above, you may
wish to have a report sys-spec printed
on the laser printer on the system sys2; the
command could be:
uux "sys2!troff -ms sys-spec | sys2!lpr -dlaser"
Assuming that there is a tape of
tar format mounted on the
/dev/rmt0 tape drive on the
system sys2, and that you are on
system sys0, then the command to
determine the table of contents
of the tar tape would be:
$PROMPT$
That is correct!
You've got it on the 2nd try.
Good, you understand the concept.
Please type
uux "tar tv sys2!/dev/rmt0"
Please type
uux "tar tv sys2!/dev/rmt0"
You will be helped this time!
FORGET1
uux "tar tv sys2!/dev/rmt0"
Observe the result above.
If your system were connected by wire or a telephone to
both systems sys1 and sys2, you could get
a listing of directories on both systems at once and
send the result to a local file twosysdata by
entering a command:
uux "!ls -l sys1!/usr/bin sys2!/bin > twosysdata"
Please enter a command above that will compare two files
/u/863 on the system sys1 and a file /a/863
on the system sys2 and send the result to
a local file diffres.
$PROMPT$
That is correct!
You've got it on the 2nd try.
Good, you understand the concept.
Please type
uux "!diff sys1!/u/863 sys2!/a/863 > !diffres"
Please type
uux "!diff sys1!/u/863 sys2!/a/863 > !diffres"
You will be helped this time!
FORGET2
uux "!diff sys1!/u/863 sys2!/a/863 > !diffres"
