- .SH NAME
- uucp
- \(em system-to-system copy
- .SH SYNOPSIS
- .LP
- .nf
- uucp \fB[\fR-cCdfjmr\fB] [\fR-n \fIuser\fB] \fIsource-file\fR... \fIdestination-file\fR
- .fi
- .SH DESCRIPTION
- The
- .IR uucp
- utility shall copy files named by the
- .IR source-file
- argument to the
- .IR destination-file
- argument. The files named can be on local or remote systems.
- .P
- The
- .IR 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\(hy2008.
- .P
- Typical implementations of this utility require a communications line
- configured to use the Base Definitions volume of POSIX.1\(hy2017,
- .IR "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.
- .SH OPTIONS
- The
- .IR uucp
- utility shall conform to the Base Definitions volume of POSIX.1\(hy2017,
- .IR "Section 12.2" ", " "Utility Syntax Guidelines".
- .P
- The following options shall be supported:
- .IP "\fB\-c\fP" 10
- Do not copy local file to the spool directory for transfer to the
- remote machine (default).
- .IP "\fB\-C\fP" 10
- Force the copy of local files to the spool directory for transfer.
- .IP "\fB\-d\fP" 10
- Make all necessary directories for the file copy (default).
- .IP "\fB\-f\fP" 10
- Do not make intermediate directories for the file copy.
- .IP "\fB\-j\fP" 10
- Write the job identification string to standard output. This job
- identification can be used by
- .IR uustat
- to obtain the status or terminate a job.
- .IP "\fB\-m\fP" 10
- Send mail to the requester when the copy is completed.
- .IP "\fB\-n\ \fIuser\fR" 10
- Notify
- .IR user
- on the remote system that a file was sent.
- .IP "\fB\-r\fP" 10
- Do not start the file transfer; just queue the job.
- .SH OPERANDS
- The following operands shall be supported:
- .IP "\fIdestination-file\fR,\ \fIsource-file\fR" 10
- .br
- 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:
- .RS 10
- .sp
- .RS 4
- .nf
- \fIsystem-name\fR!\fIpathname\fR
- .fi
- .P
- .RE
- .P
- where
- .IR system-name
- is taken from a list of system names that
- .IR uucp
- knows about.
- The destination
- .IR system-name
- can also be a list of names such as:
- .sp
- .RS 4
- .nf
- \fIsystem-name\fR!\fIsystem-name\fR!...!\fIsystem-name\fR!\fIpathname\fR
- .fi
- .P
- .RE
- .P
- 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.
- .P
- The shell pattern matching notation characters
- .BR '?' ,
- .BR '*' ,
- and
- .BR \(dq[...]\(dq
- appearing in
- .IR pathname
- shall be expanded on the appropriate system.
- .P
- Pathnames can be one of:
- .IP " 1." 4
- An absolute pathname.
- .IP " 2." 4
- A pathname preceded by ~\c
- .IR user
- where
- .IR 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
- .IR PUBDIR ;
- the actual location of
- .IR PUBDIR
- is implementation-defined).
- .IP " 3." 4
- A pathname preceded by ~/\c
- .IR destination
- where
- .IR destination
- is appended to
- .IR PUBDIR .
- .RS 4
- .TP 10
- .BR 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
- .BR '/' .
- For example,
- .BR ~/dan/
- as the destination makes the directory
- .BR PUBDIR/dan
- if it does not exist and puts the requested files in that directory.
- .P
- .RE
- .IP " 4." 4
- Anything else shall be prefixed by the current directory.
- .P
- If the result is an erroneous pathname for the remote system, the copy
- shall fail. If the
- .IR destination-file
- is a directory, the last part of the
- .IR source-file
- name shall be used.
- .P
- The read, write, and execute permissions given by
- .IR uucp
- are implementation-defined.
- .RE
- .SH STDIN
- Not used.
- .SH "INPUT FILES"
- The files to be copied are regular files.
- .SH "ENVIRONMENT VARIABLES"
- The following environment variables shall affect the execution of
- .IR uucp :
- .IP "\fILANG\fP" 10
- Provide a default value for the internationalization variables that are
- unset or null. (See the Base Definitions volume of POSIX.1\(hy2017,
- .IR "Section 8.2" ", " "Internationalization Variables"
- for the precedence of internationalization variables used to determine
- the values of locale categories.)
- .IP "\fILC_ALL\fP" 10
- If set to a non-empty string value, override the values of all the
- other internationalization variables.
- .IP "\fILC_COLLATE\fP" 10
- .br
- Determine the locale for the behavior of ranges, equivalence classes,
- and multi-character collating elements within bracketed filename
- patterns.
- .IP "\fILC_CTYPE\fP" 10
- 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,
- .BR \(dq\(aq[[:lower:]]*\(aq\(dq ).
- .IP "\fILC_MESSAGES\fP" 10
- .br
- 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.
- .IP "\fINLSPATH\fP" 10
- Determine the location of message catalogs for the processing of
- .IR LC_MESSAGES .
- .SH "ASYNCHRONOUS EVENTS"
- Default.
- .SH STDOUT
- Not used.
- .SH STDERR
- The standard error shall be used only for diagnostic messages.
- .SH "OUTPUT FILES"
- The output files (which may be on other systems) are copies of the
- input files.
- .P
- If
- .BR \-m
- is used, mail files are modified.
- .SH "EXTENDED DESCRIPTION"
- None.
- .SH "EXIT STATUS"
- The following exit values shall be returned:
- .IP "\00" 6
- Successful completion.
- .IP >0 6
- An error occurred.
- .SH "CONSEQUENCES OF ERRORS"
- Default.
- .LP
- .IR "The following sections are informative."
- .SH "APPLICATION USAGE"
- This utility is part of the UUCP Utilities option and need not be
- supported by all implementations.
- .P
- The domain of remotely accessible files can (and for obvious security
- reasons usually should) be severely restricted.
- .P
- Note that the
- .BR '!'
- character in addresses has to be escaped when using
- .IR csh
- as a command interpreter because of its history substitution syntax.
- For
- .IR ksh
- and
- .IR sh
- the escape is not necessary, but may be used.
- .P
- 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
- .IR LC_COLLATE
- and
- .IR 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.
- .SH EXAMPLES
- None.
- .SH RATIONALE
- None.
- .SH "FUTURE DIRECTIONS"
- None.
