uucp, uulog, uuname - system to system copy
uucp [ -cCdfjmr ] [ -ggrade ] [ -nusername ]
[ -x debug_level ] source-file ... destination-file
uulog [ -x ] [ -fsystem ] [ -ssystem ] [ -number ]
uuname [ -cl ]
These commands are available with the uucp software installation
option. Refer to for information on how to install optional software.
uucp copies each source-file to the named destination-file. A filename
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 by way of the speci-
fied 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 foward information (see WARNINGS below for
The shell metacharacters ?, *, and [ ] appearing in the pathname part
will be expanded on the appropriate system.
Path names may be one of:
o a full pathname;
o a pathname preceded by ~username/; username is interpreted
as a username on the specified system and is replaced by
that user's login directory on that system;
o a pathname preceded by ~/destination/; the ~/ is replaced by
the "public UUCP" directory on the remote machine 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
/usr/spool/uucppublic/dan if it does not exist and put the
requested file(s) in that directory;
o a partial pathname, which is prefixed by the pathname of
If the result is an erroneous pathname for the remote system, the copy
will fail. If the destination-file is a directory, the last component
of the source-file name is used.
uucp preserves execute permissions across the transmission and gives
0666 read and write permissions (see chmod(2V)).
uulog queries the log file /var/spool/uucp/.Log/uucico/system of uucp
transactions for system system, or the log file
/var/spool/uucp/.Log/uuxqt/system of uux(1C) transactions for system
uuname lists the UUCP names of systems that can be accessed using uucp.
-c Use the source file when copying out rather than copying the
file to the spool directory. This is the default.
-C Make a copy of outgoing files in the UUCP spool directory,
rather than copying the source file directly to the target sys-
tem. This lets you remove the source file after issuing the
-d Make all necessary directories for the file copy. This is the
-f Do not make intermediate directories for the file copy.
-j Output the job identification ASCII string on the standard out-
put. This job identification can be used by uustat(1C) to
obtain the status or terminate a job.
-m Send mail to the requester when the copy is complete.
-r Do not start uucico(8C), just queue the job.
grade is a single letter or number, from 0 to 9, A to Z, or a to
z; 0 is the highest grade, and z is the lowest grade. Lower
grades will cause the job to be transmitted earlier during a
particular conversation. The default grade is n. By way of
comparison, uux(1C) defaults to A; mail is usually sent at grade
Notify username on the remote system (that is, send username
mail) that a file was sent.
Produce debugging output on the standard output. debug_level is
a number between 0 and 9; higher numbers give more detailed
information. 5, 7, and 9 are good numbers to try; they give
increasing amounts of detail.
-x Look in the uuxqt(8C) log file for the given system.
Does a `tail -f' of the file transfer log for system. You must
hit BREAK to exit this function.
Print information about work involving system system.
Indicate that a tail command of number lines should be executed.
-c Display the names of systems known to cu(1C). The two lists are
the same, unless your machine is using different Systems files
for cu and uucp. See the Sysfiles file.
-l Display the local system name.

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 dis-
tributed, the remotely accessible files are those whose names begin
/usr/spool/uucppublic (equivalent to ~/).
All files received by uucp will be owned by the user ID uucp.
The -m option will only work sending files or receiving a single file.
Receiving multiple files specified by special shell characters ?, *,
and [ ] will not activate the -m option.
The forwarding of files through other systems may not be compatible
with other versions of UUCP. If forwarding is used, all systems in the
route must have the same version of UUCP.
When invoking uucp from csh(1), the ! character must be prefixed by
the \ escape to inhibit csh's history mechanism. Quotes are not suffi-
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.
