uucp, uulog, uuname - UNIX-to-UNIX system copy
uucp [ options ] source-files destination-file
uulog [ options ] -ssystem
uulog [ options ] system
uulog [ options ] -fsystem
uuname [ -l ] [ -c ]
uucp copies files named by the source-file arguments to the destination-
file argument. A file name may be a path name on your machine, or may
have the form:
where system-name is taken from a list of system names that uucp knows
about. The system-name may also be a list of names such as
in which case an attempt is made to send the file via the specified
route, to the destination. See WARNINGS and BUGS below for restrictions.
Care should be taken to ensure that intermediate nodes in the route are
willing to forward information (see WARNINGS below for restrictions).
The shell metacharacters ?, * and [...] appearing in path-name will be
expanded on the appropriate system.
Path names may be one of:
(1) a full path name;
(2) a path name preceded by ~user where user is a login name on the
specified system and is replaced by that user's login
(3) a path name preceded by ~/destination where destination is
appended to /var/spool/uucppublic; (NOTE: This destination
will be treated as a file name unless more than one file is
being transferred by this request or the destination is already
a directory. To ensure that it is a directory, follow the
destination with a '/'. For example ~/dan/ as the destination
will make the directory /var/spool/uucppublic/dan if it does
not exist and put the requested file(s) in that directory).
(4) anything else is prefixed by the current directory.
If the result is an erroneous path name 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:
-c Do not copy local file to the spool directory for transfer to
the remote machine (default).
-C Force the copy of local files to the spool directory for
-d Make all necessary directories for the file copy (default).
-f Do not make intermediate directories for the file copy.
-ggrade Grade is a single letter/number; lower ascii sequence
characters will cause the job to be transmitted earlier during
a particular conversation.
-j Output the job identification ASCII string on the standard
output. This job identification can be used by uustat to
obtain the status or terminate a job.
-m Send mail to the requester when the copy is completed.
-nuser Notify user on the remote system that a file was sent.
-r Do not start the file transfer, just queue the job.
-sfile Report status of the transfer to file. Note that the file must
be a full path name.
Produce debugging output on standard output. The debug_level
is a number between 0 and 9; higher numbers give more detailed
information. (Debugging will not be available if uucp was
compiles with -DSMALL.)
uulog queries a log file of uucp or uuxqt transactions in a file
/var/spool/uucp/.Log/uucico/system, or /var/spool/uucp/.Log/uuxqt/system.
The options cause uulog to print logging information:
-ssys Print information about file transfer work involving system
-fsystem Does a ``tail -f'' of the file transfer log for system. (You
must hit BREAK to exit this function.) Other options used in
conjunction with the above:
-x Look in the uuxqt log file for the given system.
-number Indicates that a ``tail'' command of number lines should be
uuname lists the names of systems known to uucp. The -c option returns
the names of systems known to cu. (The two lists are the same, unless
your machine is using different Systems files for cu and uucp. See the
Sysfiles file.) The -l option returns the local system name.
/var/spool/uucp spool directories
directory for receiving and sending
/etc/uucp/* uucp system data files
/usr/lib/uucp/* uucp administrative programs
mail(1), uustat(1C), uucico(1M), uux(1C), uuxqt(1M), chmod(2)
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 path name; 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 path names. As
distributed, the remotely accessible files are those whose names begin
/var/spool/uucppublic (equivalent to ~/).
All files received by uucp will be owned by uucp.
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.
The forwarding of files through other systems may not be compatible with
the previous version of uucp. If forwarding is used, all systems in the
route must have the same version of uucp.
Protected files and files that are in protected directories that are
owned by the requestor can be sent by uucp. However, if the requestor is
root, and the directory is not searchable by "other" or the file is not
readable by "other", the request will fail.
