+title: cdup Fun!

+<p>
+<a href='http://www.richlowe.net/'>Richard (richlowe)</a> and a few other people from <code>#fu</code> were talking about being able to do things like <kbd>cdup 5</kbd> to jump up 5 directories.  I thought it would be nicer if my existing <kbd>..</kbd> alias took an optional argument to do the same thing.  Here's the result (for bash):
+</p>
+
+<p>
+<pre>
+function cdup() {
+  if [ "x$1" = "x" ]; then max=1; else max=$1; fi
+  for ((i=0; i&lt;$max; i++)); do cd ..; done 
+}
+
+alias ..="cdup";
+</pre>
+</p>
+
+<p>
+So <kbd>..</kbd> works the same as it did before, but now you can do stuff like this:
+</p>
+
+<p>
+<pre>
+pabs@vault:/usr/local/share/raggle/themes&gt; ..
+pabs@vault:/usr/local/share/raggle&gt; .. 2
+pabs@vault:/usr/local&gt; 
+</pre>
+</p>
+
+<p>
+<a href='http://www.richlowe.net/cdup.zsh'>Richard's version</a> does the same thing for <a href='http://www.zsh.org/'>zsh</a>.
+</p>
