Package: grep (2.5.1.ds2-6) [essential]

GNU grep、egrep，及 fgrep

'grep' 是在檔案裡搜尋文字的工具，它可以用在命令行或指令稿裡。 即使你不想使用，你系統裡的其它套件還是可能會用到。

GNU 家族的 grep 工具可能是"grep 最快速的西部神槍手"了。 GNU grep 建構於快速的 lazy-state 匹配決定(速度大約是普通 Unix egrep 的 兩倍)，並混合了 Boyer-Moore-Gosper 演算法。使用常規表示式搜尋固定字串時， 可以排除不可能的文字，不需要檢查每個字元， 結果通常比 Unix grep 或 egrep 快很多倍。(不過如果常規表示式有包含 backreferencing，就會比較慢)
