I have an "mkcd" function in my startup files: mkcd() { mkdir -vp "$1" && cd "$1"; }

  Wait, now I'm confused. I have: mkcd() { mkdir -p "$@" && cd "$_"; } Can someone please detail the differences between $! and $_? (Apologies if I'm missing something obvious)

    $ echo "test" > /dev/null && echo !$ /dev/null $ echo "test" > /dev/null && echo $_ test

    You're thinking of $_ and !$, and I think they are equivalent - $_ is explicitly the last argument of the previous command, whereas !$ is a history expansion command. ! starts a new history expansion command, and $ is a word designator for the last word of the selected history entry. To quote man bash, " If a word designator is supplied without an event specification, the previous command is used as the event." I would not that !$ is a bash-ism, whereas $_ works at least on zsh and ksh as well as bash.
