From:が微妙に違う人もいるんですが適当に手で集計しちゃって
ください。
それよか、びっくりしたのはgrepが異様に遅いのですが
LANG=ja_JP.UTF-8 だといけないみたいで、
$ time egrep '^From:' /tmp/le.txt|wc
258 1521 12538
real 0m32.285s
user 0m32.376s
sys 0m0.024s
$ time LANG=C egrep '^From:' /tmp/le.txt|wc
258 1521 12538
real 0m0.156s
user 0m0.151s
sys 0m0.005s
200倍違うんですけど、そーゆーもんなんすか？＞grep
どうもmbrtowcでいちいちwcharにしているのが無駄に
遅いみたいですね。
よ
