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.1‐2008,
       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.1‐2008, 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

       −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:


                 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:


                 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

                  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

                 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

                 The read, write, and execute permissions given by uucp are

       Not used.

INPUT FILES         top

       The files to be copied are regular files.


       The following environment variables shall affect the execution of

       LANG      Provide a default value for the internationalization
                 variables that are unset or null. (See the Base Definitions
                 volume of POSIX.1‐2008, Section 8.2, Internationalization
                 Variables for the precedence of internationalization
                 variables used to determine the values of locale

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

                 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,

                 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.



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.



EXIT STATUS         top

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.



       The following sections are informative.


       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.
