<h4><a name="tag_04_161_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>uucp</i> utility shall copy files named by the <i>source-file</i> argument to the <i>destination-file</i> argument. The
|
|
files 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, 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
|
|
IEEE Std 1003.1-2001.</p>
|
|
|
|
<p>Typical implementations of this utility require a communications line configured to use the Base Definitions volume of
|
|
IEEE Std 1003.1-2001, <a href="../basedefs/xbd_chap11.html#tag_11">Chapter 11, General Terminal Interface</a>, 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.</p>

<p>The following operands shall be supported:</p>

|
|
<dl compact>
|
|
<dt><i>destination-file</i>, <i>source-file</i></dt>
|
|
|
|
<dd><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:
|
|
|
|
<pre>
|
|
<i>system-name</i><tt>!</tt><i>pathname</i>
|
|
</pre>
|
|
|
|
<p>where <i>system-name</i> is taken from a list of system names that <i>uucp</i> knows about. The destination <i>system-name</i>
|
|
can also be a list of names such as:</p>
|
|
|
|
<pre>
|
|
<i>system-name</i><tt>!</tt><i>system-name</i><tt>!...!</tt><i>system-name</i><tt>!</tt><i>pathname</i>
|
|
</pre>
|
|
|
|
<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>
|
|
|
|
<p>The shell pattern matching notation characters <tt>'?'</tt> , <tt>'*'</tt> , and <tt>"[...]"</tt> appearing in <i>pathname</i>
|
|
shall be expanded on the appropriate system.</p>
|
|
|
|
<p>Pathnames can be one of:</p>
|
|
|
|
<ol>
|
|
<li>
|
|
<p>An absolute pathname.</p>
|
|
</li>
|
|
|
|
<li>
|
|
<p>A pathname preceded by ˜ <i>user</i> where <i>user</i> 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 <i>PUBDIR</i>;
|
|
the actual location of <i>PUBDIR</i> is implementation-defined).</p>
|
|
</li>
|
|
|
|
<li>
|
|
<p>A pathname preceded by ˜/ <i>destination</i> where <i>destination</i> is appended to <i>PUBDIR</i>. <basefont size="2"></p>
|
|
|
|
<dl>
|
|
<dt><b>Note:</b></dt>
|
|
|
|
<dd>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 <tt>'/'</tt> . For example, <b>˜/dan/</b>
|
|
as the destination makes the directory <b>PUBDIR/dan</b> if it does not exist and puts the requested files in that directory.</dd>

<h4><a name="tag_04_161_16"></a>APPLICATION USAGE</h4>
|
|
|
|
<blockquote>
|
|
<p>The domain of remotely accessible files can (and for obvious security reasons usually should) be severely restricted.</p>
|
|
|
|
<p>Note that the <tt>'!'</tt> 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 <a href="../utilities/sh.html"><i>sh</i></a> the escape is not necessary, but
|
|
may be used.</p>
|
|
|
|
<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 <i>LC_COLLATE</i> and <i>LC_CTYPE .</i> 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.</p>
