grep.c (仿unix命令grep)
grep.c (仿unix命令grep) 約1697行, 48K
* grep 原本主要是在 unix/linux 下被用來找出 含/不含 某字串的工具,
而在DOS下也可找到相容的grep.exe
* 在Windows下使用grep.exe時, 請先進 "命令提示元" 環境下操作
* 例1: 找含字串 2010 的文字行 ==>
grep.exe 2010 input.txt > output.txt
* 例2: 找以 abc 開頭, 且末尾是 789 的文字行 ==>
grep.exe "^abc.*789$" input.txt > output.txt
註: ^ 表示後面的字在一行的開頭
. 表示任意字
* 表示前面的字出現任意次
$ 表示前面的字在一行的末尾
* 例3 :找不含 the 的文字行 ==>
grep.exe -v the input.txt > output.txt
