uucp, uulog, uuname - UNIX-to-UNIX system copy
uucp [-c | -C] [-d | -f] [-ggrade] [-jmr] [-nuser] [-
sfile] [-xdebug_level] source-file destination-file
uulog [-ssys] [-fsystem] [-x] [-number] system
uuname [-c | -l]
The uucp utility copies files named by the source-file argu-
ments to the destination-file argument.
The uulog utility queries a log file of uucp or uuxqt tran-
sactions in file /var/uucp/.Log/uucico/system or
The uuname utility lists the names of systems known to uucp.
The following options are supported by uucp:
-c Does not copy local file to the spool directory for
transfer to the remote machine (default).
-C Forces the copy of local files to the spool directory
-d Makes all necessary directories for the file copy
-f Does not make intermediate directories for the file
grade can be either a single letter, number, or a
string of alphanumeric characters defining a service
grade. The uuglist command can determine whether it is
appropriate to use the single letter, number, or a
string of alphanumeric characters as a service grade.
The output from the uuglist command will be a list of
service grades that are available, or a message that
says to use a single letter or number as a grade of
-j Prints the uucp job identification string on standard
output. This job identification can be used by uustat
to obtain the status of a uucp job or to terminate a
uucp job. The uucp job is valid as long as the job
remains queued on the local system.
-m Sends mail to the requester when the copy is complete.
Notifies user on the remote system that a file was
-r Does not start the file transfer, just queue the job.
Reports status of the transfer to file. This option is
accepted for compatibility, but it is ignored because
it is insecure.
Produce debugging output on standard output.
debug_level is a number between 0 and 9. As
debug_level increases to 9, more detailed debugging
information is given. This option may not be available
on all systems.
The following options cause uulog to print logging informa-
Prints information about file transfer work involving

Other options used in conjunction with the above options
-x Looks in the uuxqt log file for the given system.
Executes a tail command of number lines.
The following options are supported by uuname:
-c Displays the names of systems known to cu. The two
lists are the same, unless your machine is using dif-
ferent Systems files for cu and uucp. See the Sysfiles
-l Displays the local system name.
The source 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. source_file is restricted to no more than
one system-name. The destination system-name may also
include a list of system names such as
In this case, an attempt is made to send the file, using the
specified route, to the destination. Care should be taken to
ensure that intermediate nodes in the route are willing to
forward information (see NOTES below for restrictions).
For C-Shell users, the exclamation point (!) character must
be surrounded by single quotes ('), or preceded by a
The shell metacharacters ?, * and [...] appearing in path-
name will be expanded on the appropriate system.
Pathnames may be one of the following:
1. An absolute pathname.
2. A pathname preceded by ~user where user is a login name
on the specified system and is replaced by that user's
3. A pathname preceded by ~/destination where destination is
appended to /var/spool/uucppublic. (Note: This destina-
tion will be treated as a filename unless more than one
file is being transferred by this request or the destina-
tion is already a directory. To ensure that the destina-
tion is a directory, follow it with a forward slash (/).
For example, ~/dan/ as the destination will create the
directory /var/spool/uucppublic/dan if it does not exist
and put the requested file(s) in that directory).
Anything else is prefixed by the current directory.
If the result is an erroneous path name for the remote sys-
tem, the copy will fail. If the destination-file is a direc-
tory, the last part of the source-file name is used.
Invoking uucp with shell wildcard characters as the remote
source-file invokes the uux(1C) command to execute the uucp
command on the remote machine. The remote uucp command
spools the files on the remote machine. After the first
session terminates, if the remote machine is configured to
transfer the spooled files to the local machine, the remote
machine will initiate a call and send the files; otherwise,
the user must "call" the remote machine to transfer the
files from the spool directory to the local machine. This
call can be done manually using Uutry(1M), or as a side
effect of another uux(1C) or uucp call.
Notice that the local machine must have permission to exe-
cute the uucp command on the remote machine in order for the
remote machine to send the spooled files.
uucp removes execute permissions across the transmission and
gives 0666 read and write permissions (see chmod(2)).
See environ(5) for descriptions of the following environment
variables that affect the execution of uucp: LANG, LC_ALL,
LC_COLLATE, LC_CTYPE, LC_MESSAGES, LC_TIME, NLSPATH, and TZ.
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

For security reasons, the domain of remotely accessible
files may be severely restricted. You will probably not be
able to access files by path name; ask a responsible person
on the remote system to send them to you. For the same rea-
sons you will probably not be able to send files to arbi-
trary 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 when sending files or receiving
a single file. Receiving multiple files specified by special
shell characters ?, &, and [...] will not activate the -m
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 compatible ver-
sions of uucp.
Protected files and files that are in protected directories
that are owned by the requester can be sent by uucp. How-
ever, if the requester is root, and the directory is not
searchable by "other" or the file is not readable by
"other", the request will fail.
Strings that are passed to remote systems may not be
evaluated in the same locale as the one in use by the pro-
cess that invoked uucp on the local system.
Configuration files must be treated as C (or POSIX) locale
