Sometimes I wonder about my life. I lead a small life. Well, valuable but small. And sometimes I wonder, do I do it because I like it, or because I haven't been brave? So much of what I see reminds me of something I read in a book, when shouldn't it be the other way around? I don't really want an answer. I just want to send this cosmic question out into the void. So good night, dear void.
Mac OS X (10.4) 上默认安装的 bash 还是经典的 2.05b 版, 不如 3.x 强大. 自己下载编译了 3.2.17 编译安装, 一切顺利. 但是启动 bash 3.2.17 后发现 COLUMNS 和 LINES 这两个变量没有定义, 不过在改变终端窗口大小后就有定义了, 有些麻烦, 只好在 bashrc 里面给 bash 发一个 SIGWINCH 信号:
