bash根据用户输入搜索文件并创建新文件

Question

在下面的bash中，打开程序时会下载一个文件，然后根据用户输入搜索该文件，并将结果写入新文件。 截至目前，文件已下载并提示用户输入，但在输入后没有任何反应。

例如，打开bash并下载下载.txt，然后用户输入 id （NA04520）。id 用于搜索下载.txt行用于匹配.txt。代码运行，但没有输出结果。最终，我将在找到 id 的行中搜索特定文本，但我认为根据用户输入进行搜索是一个好的开始。谢谢:)。

cd 'C:UserscmccabeDesktopwget'
wget -O getCSV.txt http://xxx.xx.xxx.xxx/data/getCSV.csv --progress=bar:force 2>&1 | tail -f -n +6 
{
printf "nn"
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
}

input=$id    
while read -r line
do
case $line in 
    *$id*) 
        echo $line " yes" >> bashgrep.txt
        ;;
    *)
            echo "no"
            ;;

将 while 循环更改为：

while IFS= read -r line
do
case "$line" in 
    *$id*) 
        echo "$line" >> bashgrep.txt
        echo "yes"
#Assumed you want only $line to go to the file and print yes to stdout
        ;;
    *)
        echo "no"
        ;;
esac
done <download.txt 
#change it to the name of the file downloaded. 
#Your posted code seems to download getCSV.txt
