Is there a shortcut to mkdir foo and immediately cd into it?

Question

This is something I do frequently

$ mkdir foo
$ cd foo

This works as a single command, but it's more keystrokes and saves no time.

$ mkdir foo && cd foo

Is there a shortcut for this?

Edit

With the use of help below, this seems to be the most elegant answer.

# ~/.bashrc
function mkcd {
  if [ ! -n "$1" ]; then
    echo "Enter a directory name"
  elif [ -d $1 ]; then
    echo "\`$1' already exists"
  else
    mkdir $1 && cd $1
  fi
}

Answer 1

You can try something like this:

#!/bin/sh
mkdir $1 && cd $1

Save this script to some place that is in your path, for example, /usr/local/bin or ~/bin (you have to put this last one into your path in your ~/.profile file). Then you can simply call it.

Answer 2

I'm no Linux/bash expert, but try putting this in your .bashrc.

function mkdir
{
  command mkdir $1 && cd $1
}

PS Thanks to Dennis for using command mkdir.

Answer 3

If you don't want another function, to remember:

$ mkdir /home/foo/doc/bar && cd $_

Answer 4

What about:

$ mkdir newdirname; cd $_

It's a bit easier than using &&, combining quack quixote's and kzh's answers.
