PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME         top

       uucp — system-to-system copy

SYNOPSIS         top

       uucp [-cCdfjmr] [-n user] source-file... destination-file

DESCRIPTION         top

       The uucp utility shall copy files named by the source-file
       argument to the destination-file argument. The files named can be
       on local or remote systems.

       The uucp utility cannot guarantee support for all character
       encodings in all circumstances. For example, transmission data
       may be restricted to 7 bits by the underlying network, 8-bit data
       and filenames need not be portable to non-internationalized
       systems, and so on. Under these circumstances, it is recommended
       that only characters defined in the ISO/IEC 646:1991 standard
       International Reference Version (equivalent to ASCII) 7-bit range
       of characters be used, and that only characters defined in the
       portable filename character set be used for naming files. The
       protocol for transfer of files is unspecified by POSIX.1‐2008.

       Typical implementations of this utility require a communications
       line configured to use the Base Definitions volume of
       POSIX.1‐2017, Chapter 11, General Terminal Interface, but other
       communications means may be used. On systems where there are no
       available communications means (either temporarily or
       permanently), this utility shall write an error message
       describing the problem and exit with a non-zero exit status.

OPTIONS         top

       The uucp utility shall conform to the Base Definitions volume of
       POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines.

       The following options shall be supported:

       -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 transfer.

       -d        Make all necessary directories for the file copy
                 (default).

       -f        Do not make intermediate directories for the file copy.

       -j        Write the job identification string to 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.

       -n user   Notify user on the remote system that a file was sent.

       -r        Do not start the file transfer; just queue the job.

OPERANDS         top

       The following operands shall be supported:

       destination-file, source-file
                 A pathname of a file to be copied to, or from,
                 respectively. Either name can be a pathname on the
                 local machine, or can have the form:

                     system-name!pathname

                 where system-name is taken from a list of system names
                 that uucp knows about.  The destination system-name can
                 also be a list of names such as:

                     system-name!system-name!...!system-name!pathname

                 in which case, an attempt is made to send the file via
                 the specified route to the destination. Care should be
                 taken to ensure that intermediate nodes in the route
                 are willing to forward information.

                 The shell pattern matching notation characters '?',
                 '*', and "[...]" appearing in pathname shall be
                 expanded on the appropriate system.

                 Pathnames can be one of:

                  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 login directory. Note that if an
                     invalid login is specified, the default is to the
                     public directory (called PUBDIR; the actual
                     location of PUBDIR is implementation-defined).

                  3. A pathname preceded by ~/destination where
                     destination is appended to PUBDIR.

                     Note:  This destination is treated as a filename
                            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 makes the directory
                            PUBDIR/dan if it does not exist and puts the
                            requested files in that directory.

                  4. Anything else shall be prefixed by the current
                     directory.

                 If the result is an erroneous pathname for the remote
                 system, the copy shall fail. If the destination-file is
                 a directory, the last part of the source-file name
                 shall be used.

                 The read, write, and execute permissions given by uucp
                 are implementation-defined.

STDIN         top

       Not used.

INPUT FILES         top

       The files to be copied are regular files.

ENVIRONMENT VARIABLES         top

       The following environment variables shall affect the execution of
       uucp:

       LANG      Provide a default value for the internationalization
                 variables that are unset or null. (See the Base
                 Definitions volume of POSIX.1‐2017, Section 8.2,
                 Internationalization Variables for the precedence of
                 internationalization variables used to determine the
                 values of locale categories.)

       LC_ALL    If set to a non-empty string value, override the values
                 of all the other internationalization variables.

       LC_COLLATE
                 Determine the locale for the behavior of ranges,
                 equivalence classes, and multi-character collating
                 elements within bracketed filename patterns.

       LC_CTYPE  Determine the locale for the interpretation of
                 sequences of bytes of text data as characters (for
                 example, single-byte as opposed to multi-byte
                 characters in arguments and input files) and the
                 behavior of character classes within bracketed filename
                 patterns (for example, "'[[:lower:]]*'").

       LC_MESSAGES
                 Determine the locale that should be used to affect the
                 format and contents of diagnostic messages written to
                 standard error, and informative messages written to
                 standard output.

       NLSPATH   Determine the location of message catalogs for the
                 processing of LC_MESSAGES.

ASYNCHRONOUS EVENTS         top

       Default.

STDOUT         top

       Not used.

STDERR         top

       The standard error shall be used only for diagnostic messages.

OUTPUT FILES         top

       The output files (which may be on other systems) are copies of
       the input files.

       If -m is used, mail files are modified.

EXTENDED DESCRIPTION         top

       None.

EXIT STATUS         top

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

CONSEQUENCES OF ERRORS         top

       Default.

       The following sections are informative.

APPLICATION USAGE         top

       This utility is part of the UUCP Utilities option and need not be
       supported by all implementations.

       The domain of remotely accessible files can (and for obvious
       security reasons usually should) be severely restricted.

       Note that the '!'  character in addresses has to be escaped when
       using csh as a command interpreter because of its history
       substitution syntax.  For ksh and sh the escape is not necessary,
       but may be used.

       As noted above, shell metacharacters appearing in pathnames are
       expanded on the appropriate system. On an internationalized
       system, this is done under the control of local settings of
       LC_COLLATE and LC_CTYPE.  Thus, care should be taken when using
       bracketed filename patterns, as collation and typing rules may
       vary from one system to another. Also be aware that certain types
       of expression (that is, equivalence classes, character classes,
       and collating symbols) need not be supported on non-
       internationalized systems.

EXAMPLES         top

       None.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
