注：如果手工在checkout出来的目录里创建了一个新文件夹newsubdir，再用svn mkdir newsubdir命
令后，SVN会提示：
svn: 尝试用 “svn <span class="built_in">add</span>”或 “svn <span class="built_in">add</span> <span class="comment">--non-recursive”代替？</span>
svn: 无法创建目录“hello”: 文件已经存在此时，用如下命令解决：
svn <span class="built_in">add</span> <span class="comment">--non-recursive newsubdir</span>
在进入这个newsubdir文件夹，用ls -<span class="operator">a</span>查看它下面的全部目录与文件，会发现多了：.svn目录再用 svn
mkdir -m <span class="string">"添hello功能模块文件"</span> svn://<span class="number">192.168</span><span class="number">.0</span><span class="number">.3</span>/test/newdir/newsubdir 命令，
SVN提示：
svn: File already exists: filesystem <span class="string">'/data/svnroot/test/db'</span>, transaction <span class="string">'4541-1'</span>,path <span class="string">'/newdir/newsubdir '</span>

<p><strong>15、恢复本地修改 </strong></p>

2
3
</pre></td><td class="code"><pre>svn <span class="keyword">switch</span> http:<span class="comment">//目录全路径 本地目录全路径</span>
例子：
svn <span class="keyword">switch</span> http:<span class="comment">//192.163.0.3/test/456 . ＜－ (原为123的分支)当前所在目录分支到192.163.0.3/test/456</span>

<p><strong>17、解决冲突 </strong></p>
<figure class="highlight"><table><tr><td class="gutter"><pre>1
2
3
4
5
</pre></td><td class="code"><pre>svn resolved [本地目录全路径]
例子：
$ svn <span class="operator"><span class="keyword">update</span>
C foo.c
Updated <span class="keyword">to</span> revision <span class="number">31.</span></span>
</pre></td></tr></table></figure>
<p>如果你在更新时得到冲突，你的工作拷贝会产生三个新的文件：</p>
<figure class="highlight"><table><tr><td class="gutter"><pre>1
2
3
4
5
</pre></td><td class="code"><pre>$ ls
foo<span class="preprocessor">.c</span>
foo<span class="preprocessor">.c</span><span class="preprocessor">.mine</span>
foo<span class="preprocessor">.c</span><span class="preprocessor">.r</span>30
foo<span class="preprocessor">.c</span><span class="preprocessor">.r</span>31
</pre></td></tr></table></figure>
<p>当你解决了foo.c的冲突，并且准备提交，运行svn resolved让你的工作拷贝知道你已经完成了所有事情。
你可以仅仅删除冲突的文件并且提交，但是svn resolved除了删除冲突文件，还修正了一些记录在工作拷贝管理区域的记录数据，所以我们推荐你使用这个命令。</p>
<p><strong>18、不checkout而查看输出特定文件或URL的内容 </strong></p>
<figure class="highlight"><table><tr><td class="gutter"><pre>1
2

</pre></td><td class="code"><pre>svn cat http:<span class="comment">//文件全路径</span>
例子：
svn cat http:<span class="comment">//192.168.0.3/test/readme.txt</span>
