UUCP(1)                    POSIX Programmer's Manual                   UUCP(1)



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

NAME
       uucp -- system-to-system copy

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

DESCRIPTION
       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
       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
       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
       Not used.

INPUT FILES
       The files to be copied are regular files.

ENVIRONMENT VARIABLES
       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
       Default.

STDOUT
       Not used.

STDERR
       The standard error shall be used only for diagnostic messages.

OUTPUT FILES
       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
       None.

EXIT STATUS
       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

CONSEQUENCES OF ERRORS
       Default.

       The following sections are informative.

APPLICATION USAGE
       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
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
