Linux 2.6 - man page for uucp (linux section 1posix)

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

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  circum-
       stances. For example, transmission data may be restricted to 7 bits by the underlying net-
       work, 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 IEEE Std 1003.1-2001.

       Typical	implementations  of  this utility require a communications line configured to use
       the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 11, General  Terminal  Inter-
       face,  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 IEEE Std 1003.1-2001,
       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 destina-
       tion 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 destina-
       tion.  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  path-
       name 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 sys-
		  tem 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 exam-
		     ple, ~/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 IEEE Std 1003.1-2001, Section 8.2, Inter-
	      nationalization 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  interna-
	      tionalization 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 argu-
	      ments and input files) and the behavior of character classes within bracketed file-
	      name patterns (for example, "'[[:lower:]]*'" ).

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diag-
	      nostic 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
       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	appropri-
       ate  system.  On an internationalized system, this is done under the control of local set-
       tings of LC_COLLATE and LC_CTYPE . Thus, care should be taken when using  bracketed  file-
       name  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.
