--- date: "2003-11-06T19:20:55Z" 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=$1; fi for ((i=0; i<$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> .. pabs@vault:/usr/local/share/raggle> .. 2 pabs@vault:/usr/local> </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>
