Looks cool, but nothing much happens for me. I used brew to install go, then ran the following: % type -a go /usr/local/bin/go % cd tsukae % go get -d ./... go: downloading github.com/inconshreveable/mousetrap v1.0.0 % go run main.go o: downloading github.com/spf13/cobra v1.1.3 go: downloading github.com/gizak/termui/v3 v3.1.0 go: downloading github.com/mattn/go-runewidth v0.0.2 go: downloading github.com/nsf/termbox…

cd tsukae go build ./tsukae

Closer! That got me the executable. Now I get a stack trace....

  % ./tsukae bash

Earlier quoted context omitted.

Going to my home dir is another frequent operation for me so I also have alias ~='pushd ~' (Those are tildes but may look like dashes depending on your font and size...) Not as fancy as some other aliases I see here but does the (basic) trick.

A raw "cd" with no arguments will take you back to your home-directory. Of course "~" is one less character to type, but on the off-chance you didn't know.

As we're offering alternatives. Either `shopt autocd` in bash or `setopt auto_cd` in zsh, then ~ changes to home by simply being a path.

i figured it out, you just need to have bigger history, currently you only have 4 unique commands in your hist file.
