title: symbolic link can only be created from parent to child under FreeBSD?

  <p>In the current directory(test), I have used </p>
  
  <pre><code>echo date &gt; date.sh ; chmod u+x date.sh
  </code></pre>
  
  <p>to create date.sh and make it executable. </p>
  
  <p>Then I used</p>
  
  <pre><code>ln -s date.sh ../date.sh.sym1
  ln -s ./date.sh ../date.sh.sym2
  </code></pre>
  
  <p>to create two symbolic links in the parent directory from which I typed </p>
  
  <pre><code>./date.sh.sym1
  ./date.sh.sym2
  </code></pre>
  
  <p>The result was that both showed command not found.
  Then in the parent directory, I used </p>
  
  <pre><code>ln -s test/date.sh date.sh.sym3
  </code></pre>
  
  <p>to create another symlink. This time it becomes executable after I typed</p>
  
  <pre><code>./date.sh.sym3
  </code></pre>
  
  <p>Is it because symlink can only be created from parent to child ? (FreeBSD 10.2)</p>
