vi不会,但会用sed-->sed -e '/.*abcdef/d' < infile > outfile

你真能够记的.我现在用C习惯了,什么一想,写个C也就15分钟的事情.就什么命令格式都不记了.

你用C15分钟,人grep 15秒都不到。

问这个问题的时间就不止15分钟了,何况,大部分的问题哪有这么简单的,我也不反对使用命令,只是对于我来说,写C就和写SCRIPT没有什么区别.其实,SCRIPT我也写的.当我也使用命令的时候.

象这些话,我压根就不会放在心上.我有自知之明,这些SCRIPT,我是很差的,都是要用的时候才急急忙忙地去读MANUAL.

曾经写过EMAIL分析程序,人写的EMAIL,程序分析,其实也就是一些规则而已,字符从一边流入,根据状态和规则进行分析,也写过语法严密的分析执行程序,也是差不多,至于大规模的数据文件处理,也是很容易的.习惯了就好.而用命令,有时候就不那么简单了.
你也太幽默了点吧, 偷偷塞个贴子在这里,以为我发现不了?
