Thefiles named can be on local or remote systems.</p><p>The <i>uucp</i> utility cannot guarantee support for all character encodings in all circumstances. For example, transmissiondata may be restricted to 7 bits by the underlying network, 8-bit data and filenames need not be portable to non-internationalizedsystems, and so on. Under these circumstances, it is recommended that only characters defined in the ISO/IEC 646:1991 standardInternational Reference Version (equivalent to ASCII) 7-bit range of characters be used, and that only characters defined in theportable filename character set be used for naming files. The protocol for transfer of files is unspecified byIEEE Std 1003.1-2001.</p><p>Typical implementations of this utility require a communications line configured to use the Base Definitions volume ofIEEE Std 1003.1-2001, <a href="../basedefs/xbd_chap11.html#tag_11">Chapter 11, General Terminal Interface</a>, but othercommunications 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.</p></blockquote><h4><a name="tag_04_161_04"></a>OPTIONS</h4><blockquote><p>The <i>uucp</i> utility shall conform to the Base Definitions volume of IEEE Std 1003.1-2001, <a href="../basedefs/xbd_chap12.html#tag_12_02">Section 12.2, Utility Syntax Guidelines</a>.</p><p>The following options shall be supported:</p><dl compact><dt><b>-c</b></dt><dd>Do not copy local file to the spool directory for transfer to the remote machine (default).</dd><dt><b>-C</b></dt><dd>Force the copy of local files to the spool directory for transfer.</dd><dt><b>-d</b></dt><dd>Make all necessary directories for the file copy (default).</dd><dt><b>-f</b></dt><dd>Do not make intermediate directories for the file copy.</dd><dt><b>-j</b></dt><dd>Write the job identification string to standard output.
