bash根據用戶輸入搜索文件並創建新文件

Question

在下面的bash中，打開程序時下載文件，然後根據用戶輸入搜索該文件，並將結果寫入新文件。截至目前，文件下載和用戶被提示輸入，但輸入後沒有任何反應。

例如，打開bash並下載download.txt，然後用戶輸入id（NA04520）。該id用於搜索download.txt，並將該行寫入match.txt。代碼運行但沒有輸出結果。最終，我會搜索id中找到的特定文本，但我認爲基於用戶輸入的搜索是一個好的開始。謝謝 ：）。

{ 
printf "\n\n" 
printf "What is the id of the NGS patient: "; read id 
    [ -z "$id" ] && printf "\n No ID supplied. Leaving match function." && sleep 2 && return 
    [ "$id" = "end" ] && printf "\n Leaving match function." && sleep 2 && return 
}
