mkcd command - how to create a directory using mkdir and cd in one step

mkcd.bash

#
#   mkcd command
#   This is an improvised version of the mkcd command at http://superuser.com/questions/152794/is-there-a-shortcut-to-mkdir-foo-and-immediately-cd-into-it
#   This function has to be added to the ~/.bashrc file
#   After that you can run command like: mkdir abc, mkdir -p one/two/three
#
function mkcd {
  last=$(eval "echo \$$#")
  if [ ! -n "$last" ]; then
    echo "Enter a directory name"
  elif [ -d $last ]; then
    echo "\`$last' already exists"
  else
    mkdir $@ && cd $last
  fi
}

Thanks was just looking for exactly this.

Thanks man

function mkcd() {
    mkdir -p $@ && cd $@;
}

or you can actually just use

mkdir anything && cd $_

mkdir -p allows you to create parent dirs and also doesnt error if a dir already exists, meaning that you can still mkcd even if the dir already exists (effectively just cd)
