copy</blockquote><h4><a name = "tag_001_014_2620"> </a>SYNOPSIS</h4><blockquote><pre><code>uucp <b>[</b>-cCdfjmr<b>][</b>-n <i>user</i><b>] </b><i>source-file</i>... <i>destination-file</i></code></pre></blockquote><h4><a name = "tag_001_014_2621"> </a>DESCRIPTION</h4><blockquote>The<i>uucp</i>utilitycopies files named by the<i>source-file</i>arguments to the<i>destination-file</i>argument.The files named can be on local or remote systems.<p>The<i>uucp</i>utility cannot guarantee support for all character encodingsin all circumstances.For example,transmission data may be restricted to 7-bits by the underlyingnetwork, 8-bit data and filenames need not be portable tonon-internationalised systems, and so on.Under these circumstances, it is recommended that onlycharacters defined in theISO/IEC 646:1991 standard International Reference Version(equivalent to ASCII) 7-bit range ofcharacters be used, and that only characters defined in the PortableFilename Character Set be used for naming files.</blockquote><h4><a name = "tag_001_014_2622"> </a>OPTIONS</h4><blockquote>The<i>uucp</i>utility supports the <b>XBD</b> specification, <a href="../xbd/utilconv.html#usg"><b>Utility Syntax Guidelines</b> </a> .The following options are supported:<dl compact><dt><b>-c</b><dd>Do not copy local file to the spool directory for transfer to the remotemachine (default).<dt><b>-C</b><dd>Force the copy of local files to the spool directory for transfer.<dt><b>-d</b><dd>Make all necessary directories for the file copy (default).<dt><b>-f</b><dd>Do not make intermediate directories for the file copy.<dt><b>-j</b><dd>Write the job identification string to standard output.This job identification can be used by<i><a href="uustat.html">uustat</a></i>to obtain the status or terminate a job.<dt><b>-m</b><dd>Send mail to the requester when the copy iscompleted.<dt><b>-n </b><i>user</i><dd>Notify<i>user</i>on the remote system that a file was sent.<dt><b>-r</b><dd>Do not start the file transfer; just queue the job.</dl></blockquote><h4><a name = "tag_001_014_2623"> </a>OPERANDS</h4><blockquote>The following operands are supported:<dl compact><dt><i>destination-file</i><dd><dt><i>source-file</i><dd>A pathname of a file to be copied to, or from, respectively.Either name can be a pathname on the local machine, or canhave the form:<pre><code><i>system-name</i>!<i>pathname</i></code></pre>where<i>system-name</i>is taken from a list of system names that<i>uucp</i>knows about; see<i><a href="uuname.html">uuname</a></i>.The destination<i>system-name</i>can also be a list of names such as:<pre><code><i>system-name</i>!<i>system-name</i>!<i>...</i>!<i>system-name</i>!<i>pathname</i></code></pre>in which case, an attempt is made to send the file via the specified routeto the destination.Care should be taken to ensure that intermediate nodes in theroute are willing to forward information.The shell pattern matching notation characters"?", "*" and[...]appearing in<i>pathname</i>will be expanded on the appropriate system.Pathnames can be one of:<ol><li>An absolute pathname.<li>A pathname preceded by<i>~user</i>where<i>user</i>is a login name on the specified systemand is replaced by that user's login directory.Note that if an invalid login is specified, the default isto the public directory (called<i>"PUBDIR"</i>;the actual location of<i>PUBDIR</i>is implementation-dependent).<li>A pathname preceded by<i>~/destination</i>where<i>destination</i>is appended to<i>PUBDIR.</i><dl><dt><b>Note:</b><dd>This destination will be treated as a filename unlessmore than one file is being transferred by this request orthe destination is already a directory.To ensure that it is a directory, follow the destination with a /.For example,<b>~/dan/</b>as the destination will make the directory<i>PUBDIR</i><b>/dan</b>if it does not exist and put the requested filesin that directory.</dl><p><li>Anything else is prefixed by the current directory.<p></ol><p>If the result is an erroneous pathname for the remote system,the copy will fail.If the<i>destination-file</i>is a directory, the last part of the<i>source-file</i>name is used.<p>The read, write and execute permissions given by<i>uucp</i>are implementation-dependent.<p></dl></blockquote><h4><a name = "tag_001_014_2624"> </a>STDIN</h4><blockquote>Not used.</blockquote><h4><a name = "tag_001_014_2625"> </a>INPUT FILES</h4><blockquote>The files to be copied are regular files.</blockquote><h4><a name = "tag_001_014_2626"> </a>ENVIRONMENT VARIABLES</h4><blockquote>The following environment variables affect the execution of<i>uucp</i>:<dl compact><dt><i>LANG</i><dd>Provide a default value for the internationalisation variablesthat are unset or null.If<i>LANG</i>is unset or null, the corresponding value from theimplementation-dependent default locale will be used.If any of the internationalisation variables contains an invalid setting, theutility will behave as if none of the variables had been defined.<dt><i>LC_ALL</i><dd>If set to a non-empty string value,override the values of all the other internationalisation variables.<dt><i>LC_COLLATE</i><dd>Determine the locale for thebehaviour of ranges, equivalence classesand multi-character collating elementswithin bracketed filename patterns.<dt><i>LC_CTYPE</i><dd>Determine thelocale for the interpretation of sequences of bytes of text data ascharacters (for example, single- as opposed to multi-byte charactersin arguments and input files)and the behaviour of character classeswithin bracketed filename patterns(for example,'[[:lower:]]*').<dt><i>LC_MESSAGES</i><dd>Determine the locale that should be used to affectthe format and contents of diagnosticmessages written to standard error,and informative messages written to standard output.<dt><i>LC_TIME</i><dd>Determine the format of date and time strings output by<i>uucp</i>.<dt><i>NLSPATH</i><dd>Determine the location of message cataloguesfor the processing of<i>LC_MESSAGES .</i><dt><i>TZ</i><dd>Determine the timezone used with date and time strings.</dl></blockquote><h4><a name = "tag_001_014_2627"> </a>ASYNCHRONOUS EVENTS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_2628"> </a>STDOUT</h4><blockquote>Not used.</blockquote><h4><a name = "tag_001_014_2629"> </a>STDERR</h4><blockquote>Used only for diagnostic messages.</blockquote><h4><a name = "tag_001_014_2630"> </a>OUTPUT FILES</h4><blockquote>The output files (which may be on other systems)are copies of the input files.<p>If the<b>-m</b>is used, mail fileswill be modified.</blockquote><h4><a name = "tag_001_014_2631"> </a>EXTENDED DESCRIPTION</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2632"> </a>EXIT STATUS</h4><blockquote>The following exit values are returned:<dl compact><dt>0<dd>Successful completion.<dt>>0<dd>An error occurred.</dl></blockquote><h4><a name = "tag_001_014_2633"> </a>CONSEQUENCES OF ERRORS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_2634"> </a>APPLICATION USAGE</h4><blockquote>The domain of remotely accessible files can(and for obvious security reasons usually should)be severely restricted.<p>Note that the"!"character in addresses has to be escaped when using<i>csh</i>as a command interpreter because of its history substitution syntax.For<i>ksh</i>and<i><a href="sh.html">sh</a></i>the escape is not necessary, but may be used.<p>Typical implementations of this utility require a communicationsline configured to use the <b>XBD</b> specification, <a href="../xbd/termios.html"><b>General Terminal Interface</b> </a> ,but other communications means may be used.On systems where there are no available communications means(either temporarily or permanently), thisutility will write an error message describing the problemand exit with a non-zero exit status.<br><p>As noted above, shell metacharacters appearing in pathnamesare expanded on the appropriate system.On an internationalisedsystem, this is done under the control of local settings of<i>LC_COLLATE</i>and<i>LC_CTYPE .</i>Thus, care should be taken when usingbracketed filename patterns, as collation and typing rules may varyfrom one system to another.Also be aware that certain types ofexpression (that is, equivalence classes, character classes and collatingsymbols) need not be supported on non-internationalised systems.</blockquote><h4><a name = "tag_001_014_2635"> </a>EXAMPLES</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2636"> </a>FUTURE DIRECTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2637">
