Make and Change Directory Shell Alias

If you’ve ever cursed the fact that you need to mkdir <dirname> followed by cd <dirname> to create and change into a new directory, this snippet is for you.

function mcd() {
    mkdir "$@" && cd "$@"
}

Just paste that into your shell configuration (.bashrc or .zshrc in your home folder), restart your shell, and start making and changing into directories with just mcd <dirname>.
