Emacs, screen の次が zsh かぁ。僕が、zsh に移ったのは、消去
法的理由。前にも書いたけど、

　tcsh は、文法がアドホックすぎ

で、

　bash は、実装がアドホックすぎ

だから。2005/3 に移行したらしいです。どうして、それまでtcsh
で我慢できてたかが不思議。

でも、zsh は認知度が低すぎ。.cshrc converter でもあれば、移
行しやすかと思うが、敷居も高いね。自分でも .zshrc が安定す

ニュアル読んだ割には、zsh の売りの「豊富なcompletion」には
手をつけませんでした。ssh/mh のcompletion ぐらい設定するか...

その記事だと、
　setopt share_history # 同一ホストで動いているZshで履歴を共有
とかが出てる。微妙だなぁ。

僕は、端末毎にhistoryを別にして欲しいので、

　tty=$TTY:t
　HISTFILE=$HOME/.history.$tty

とかしてます。

　alias h="fc -l -d -20"

として、history に時間を入れているのは「プログラミングに夢
中になりすぎ」を反省するためです。最近は、「昨日、いつ寝た
か」を確認するために使うことが多い。

Windows でも使えるしね。ただ、Fedora Core でデフォルトで入
ってないのが困る。

equally true that we experience every hour the
results of our deplorable condition? What does this chaos and monstrous
confusion proclaim to us but the truth of these two states, with a voice so
powerful that it is impossible to resist it?

436. Weakness.--Every pursuit of men is to get wealth; and they cannot have
a title to show that they possess it justly, for they have only that of
human caprice; nor have they strength to hold it securely. It is the same
with knowledge, for disease takes it away. We are incapable both of truth
and goodness.

437. We desire truth, and find within ourselves only uncertainty.

We seek happiness, and find only misery and death.

We cannot but desire truth and happiness, and are incapable of certainty or
happiness. This desire is left to us, partly to punish us, partly to make us
perceive wherefrom we are fallen.

438. If man is not made for God, why is he only happy in God? If man is made
for God, why is he so opposed to God?

439. Nature corrupted.--Man does not act by reason, which constitutes his
being.

440. The corruption of reason is shown by the existence of so many different
and extravagant customs. It was necessary that truth should come, in order
that man should no longer dwell within himself.

441. For myself, I confess that, so soon as the Christian religion reveals
the principle that human nature is corrupt and fallen from God, that opens
my eyes to see everywhere the mark of this truth: for nature is such that
she testifies everywhere, both within man and without him, to a lost God and
a corrupt nature.

442. Man's true nature, his true good, true v
