uucp - unix to unix copy
uucp [ -acCdfmr ] [ -nuser ] [ -ggrade ] [ -sspool ] [ -xdebug ] source-file.... destination-file
Uucp copies files named by the source-file arguments to the destination-file argument. A file name may be a pathname on your machine, or
may have the form
where `system-name' is taken from a list of system names that uucp knows about. Shell metacharacters ?* appearing in the pathname part
will be expanded on the appropriate system.
Pathnames may be one of:(1) a full pathname;
(2) a pathname preceded by ~user; where user is a userid on the specified system and is replaced by that user's login directory;
(3) a pathname prefixed by ~, where ~ is expanded into the system's public directory (usually /usr/spool/uucppublic);
(4) a partial pathname, which is prefixed by the current directory.
If the result is an erroneous pathname for the remote system, the copy will fail. If the destination-file is a directory, the last part of
the source-file name is used.
Uucp preserves execute permissions across the transmission and gives 0666 read and write permissions (see chmod(2)).
The following options are interpreted by uucp.
-a Avoid doing a getwd to find the current directory. (This is sometimes used for efficiency.)
-c Use the source file when copying out rather than copying the file to the spool directory. (This is the default.)
-C Copy the source file to the spool directory and transmit the copy.
-d Make all necessary directories for the file copy. (This is the default.)
-f Do not make intermediate directories for the file copy.
Grade is a single letter/number; lower ASCII sequence characters will cause a job to be transmitted earlier during a particular con-
versation. Default is `n'. By way of comparison, uux(1C) defaults to `A'; mail is usually sent at `C'.
-m Send mail to the requester when the copy is complete.
-nuser Notify user on remote system (i.e., send user mail) that a file was sent.
-r Do not start the transfer, just queue the job.
Use spool as the spool directory instead of the default.
Turn on the debugging at level debug.
/usr/spool/uucp - spool directory
/etc/uucp/* - data and configuration files

D. A. Nowitz, Uucp Implementation Description.
The domain of remotely accessible files can (and for obvious security reasons, usually should) be severely restricted. You will very
likely not be able to fetch files by pathname; ask a responsible person on the remote system to send them to you. For the same reasons you
will probably not be able to send files to arbitrary pathnames.
All files received by uucp will be owned by the uucp administrator (usually UID 5).
The -m option will only work sending files or receiving a single file. (Receiving multiple files specified by special shell characters
?* will not activate the -m option.)
At present uucp cannot copy to a system several "hops" away, that is, a command of the form
uucp myfile system1!system2!system3!yourfile
is not permitted. Use uusend(1C) instead.
When invoking uucp from csh(1), the `!' character must be prefixed by the `' escape to inhibit csh's history mechanism. (Quotes are not
Uucp refuses to copy a file that does not give read access to ``other''; that is, the file must have at least 0444 modes.
