学生時代(かれこれ7年ぐらい前)からFreeBSDを使っている(今はCentOSが多い)わけだけど、当時からシェルはzsh使いでした。が、さくらインターネットの共用レンタルサーバ(スタンダード)のデフォルトのシェルはcsh(tcsh)です。
tcshよりzshのほうが使いやすいと思うので、さくらインターネットでもログインシェルをzshに切り替えることに。
> chsh -s /usr/local/bin/zsh
シェルをtcshからzshに切り替えたら、.zshrcの作成。
当時使っていたzshの.zshrcはあることはあるがバージョンが古いものなので、後藤大地さんが舞い込みジャーナルで連載していた漢のzshよりコピペってきました。

これで何とか使えるものになりました。
適度に前の状態とは違いますが、それはおいおい直していくということで・・・
