The command is not executed immediately; the request is queued until the .I uucico (8) daemon calls the system and executes it. The daemon is started automatically unless the .B \-r switch is given. The actual command execution is done by the .I uuxqt (8) daemon. 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 pathname on that system follows 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 /usr/spool/uucppublic) on the appropriate system. A pathname 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 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 .I 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, .EX uux 'sys1!diff sys2!~user1/foo sys3!~user2/foo >!foo.diff' .EE 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 .I uucp command on a remote system. .SH OPTIONS The following options may be given to .I uux. .TP 5 .B \-,\-p Read standard input and use it as the standard input for the command to be executed. .TP 5 .B \-c Do not copy local files to the spool directory. This is the default. If they are removed before being processed by the .I uucico (8) daemon, the copy will fail. The files must be readable by the .I uucico (8) daemon, as well as the by the invoker of .I uux. .TP 5 .B \-C Copy local files to the spool directory. .TP 5 .B \-l 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 the .B \-c option also appears (in other words, use of .B \-l switches the default from .B \-c to .B \-C). If the files are changed before being processed by the .I uucico (8) daemon, the changed versions will be used. The files must be readable by the .I uucico (8) daemon, as well as by the invoker of .I uux. .TP 5 .B \-g 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. .TP 5 .B \-n Do not send mail about the status of the job, even if it fails. .TP 5 .B \-z Send mail about the status of the job if an error occurs. For many .I uuxqt daemons, including the Taylor UUCP .I uuxqt, this is the default action; for those, .B \-z will have no effect. However, some .I uuxqt daemons will send mail if the job succeeds unless the .B \-z option is used, and some other .I uuxqt daemons will not send mail if the job fails unless the .B \-z option is used. .TP 5 .B \-r Do not start the .I uucico (8) daemon immediately; merely queue up the execution request for later processing. .TP 5 .B \-j Print jobids on standard output. A jobid will be generated for each file copy operation required to perform the operation. These file copies may be cancelled by passing the jobid to the .B \-k switch of .I uustat (1), which will make the execution impossible to complete. .TP 5 .B \-a address Report job status to the specified e-mail address. .TP 5 .B \-x type Turn on particular debugging types. The following types are recognized: abnormal, chat, handshake, uucp-proto, proto, port, config, spooldir, execute, incoming, outgoing. Only abnormal, config, spooldir and execute are meaningful for .I uux. Multiple types may be given, separated by commas, and the .B \-x option may appear multiple times. A number may also be given, which will turn on that many types from the foregoing list; for example, .B \-x 2 is equivalent to .B \-x abnormal,chat. .TP 5 .B \-I file Set configuration file to use. This option may not be available, depending upon how .I uux was compiled. .SH EXAMPLES .EX uux -z - sys1!rmail user1 .EE Execute the command ``rmail user1'' on the system sys1, giving it as standard input whatever is given to .I uux as standard input. If a failure occurs, send a message using .I mail (1). .EX uux 'diff -c sys1!~user1/file1 sys2!~user2/file2 >!file.diff' .EE Fetch the two named files from system sys1 and system sys2 and execute .I diff putting the result in file.diff in the current directory. The current directory must be writable by the .I uuxqt (8) daemon for this to work. .EX uux 'sys1!uucp ~user1/file1 (sys2!~user2/file2)' .EE Execute .I uucp on the system sys1 copying file1 (on system sys1) to sys2. This illustrates the use of parentheses for quoting. .SH RESTRICTIONS The remote system may not permit you to execute certain commands. Many remote systems only permit the execution of .I rmail and .I rnews. Some of the options are dependent on the capabilities of the .I uuxqt (8) daemon on the remote system. .SH FILES The file names may be changed at compilation time or by the configuration file, so these are only approximations. .br /usr/lib/uucp/config - Configuration file. .br /usr/spool/uucp - UUCP spool directory. .br /usr/spool/uucp/Log - UUCP log file. .br /usr/spool/uucppublic - Default UUCP public directory. .SH SEE ALSO mail(1), uustat(1), uucp(1), uucico(8), uuxqt(8) .SH BUGS Files can not be referenced across multiple systems. Too many jobids are output by .B \-j, and there is no good way to cancel a local execution requiring remote files. .SH AUTHOR Ian Lance Taylor (ian@airs.com or uunet!airs!ian)
