       uux - Remote command execution over UUCP

       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  immedi-
       ately; the request is queued until the uucico (8) daemon calls the system and executes it.
       The daemon is started automatically unless one of the -r or --nouucico options is given.

       The actual command execution is done by the uuxqt (8) daemon.

       File arguments can be gathered from remote systems to the execution system, as  can  stan-
       dard 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 pathname on that system fol-
       lows it.  An empty system name is taken as the local system; this must be used to transfer
       a  file	to  a command being executed on a remote system.  If the path is not absolute, it
       will be appended to the current working directory on the local system; the result may  not
       be  meaningful  on  the	remote system.	A pathname may begin with ~/, in which case it is
       relative to the UUCP public directory (usually /var/spool/uucppublic) on  the  appropriate
       system.	A pathname may begin with ~name/, in which case it is relative to the home direc-
       tory of the named user on the appropriate system.

       Standard input and output may be redirected as  usual;  the  pathnames  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 base 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.

       A  request  to  execute an empty command (e.g., uux sys!)  will create a poll file for the
       specified system.

       The following options may be given to uux.

       -, -p, --stdin
	    Read standard input and use it as the standard input for the command to be executed.

       -c, --nocopy
	    Do not copy local files to the spool directory.  This is the default.   If	they  are
	    removed  before  being  processed  by the uucico (8) daemon, the copy will fail.  The
	    files must be readable by the uucico (8) daemon, as well as the  by  the  invoker  of

       -C, --copy
	    Copy local files to the spool directory.

       -l, --link
	    Link local files into the spool directory.	If a file can not be linked because it is
	    on a different device, it will be copied unless one of the	-c  or	--nocopy  options
	    also  appears  (in	other  words, use of --link switches the default from --nocopy to
	    --copy).  If the files are changed before being processed by the uucico  (8)  daemon,
	    the changed versions will be used.	The files must be readable by the uucico (8) dae-
	    mon, as well as by the invoker of uux.

       -g grade, --grade grade
	    Set the grade of the file transfer command.  Jobs of  a  higher  grade  are  executed
	    first.  Grades run 0 ... 9 A ... Z a ... z from high to low.

       -n, --notification=no
	    Do not send mail about the status of the job, even if it fails.

       -z, --notification=error
	    Send  mail	about  the status of the job if an error occurs.  For many uuxqt daemons,
	    including the Taylor UUCP uuxqt, this is the default action; for  those,  --notifica-
	    tion=error	will  have  no effect.	However, some uuxqt daemons will send mail if the
	    job succeeds unless the --notification=error option is used,  and  some  other  uuxqt
	    daemons will not send mail if the job fails unless the --notification=error option is

       -r, --nouucico
	    Do not start the uucico (8) daemon immediately; merely queue up the execution request
	    for later processing.

       -j, --jobid
	    Print jobids on standard output.  A jobid will be generated for each file copy opera-
	    tion required to perform the operation.  These file copies may be cancelled by  pass-
	    ing  the  jobid  to  the  --kill  switch of uustat (1), which will make the execution
	    impossible to complete.

       -a address, --requestor address
	    Report job status to the specified e-mail address.

       -x type, --debug type
	    Turn on particular debugging types.  The following types  are  recognized:	abnormal,
	    chat, handshake, uucp-proto, proto, port, config, spooldir, execute, incoming, outgo-
	    ing.  Only abnormal, config, spooldir and execute are meaningful for uux.

	    Multiple types may be given, separated by commas, and the --debug option  may  appear
	    multiple  times.  A number may also be given, which will turn on that many types from
	    the foregoing list; for example, --debug 2 is equivalent to --debug abnormal,chat.

       -I file, --config file
	    Set configuration file to use.  This option may not be available, depending upon  how
	    uux was compiled.

       -v, --version
	    Report version information and exit.

	    Print a help message and exit.

       uux -z - sys1!rmail user1
       Execute	the command ``rmail user1'' on the system sys1, giving it as standard input what-
       ever is given to uux as standard input.	If a failure occurs, send a  message  using  mail

       uux 'diff -c sys1!~user1/file1 sys2!~user2/file2 >!file.diff'
       Fetch  the  two	named files from system sys1 and system sys2 and execute diff putting the
       result in file.diff in the current directory.  The current directory must be  writable  by
       the uuxqt (8) daemon for this to work.

       uux 'sys1!uucp ~user1/file1 (sys2!~user2/file2)'
       Execute	uucp on the system sys1 copying file1 (on system sys1) to sys2.  This illustrates
       the use of parentheses for quoting.

       The remote system may not permit you to execute certain	commands.   Many  remote  systems
       only permit the execution of rmail and rnews.

       Some  of  the  options  are  dependent  on the capabilities of the uuxqt (8) daemon on the
       remote system.

       The file names may be changed at compilation time or by the configuration file,	so  these
       are only approximations.

       /etc/uucp/config - Configuration file.
       /etc/uucp/oldconfig/ - Alternative configuration (HDB or V2 format)
       /var/spool/uucp - UUCP spool directory.
       /var/log/uucp/Log - UUCP log file.
       /var/spool/uucppublic - Default UUCP public directory.

       mail(1), uustat(1), uucp(1), uucico(8), uuxqt(8)

       Files can not be referenced across multiple systems.

       Too  many  jobids are output by --jobid, and there is no good way to cancel a local execu-
       tion requiring remote files.
