下面的代码是使用grep查找文件，然后将其复制到一个新文件夹中，并使用新名称（found_file1 found_file2等）。
当search（）{...}被删除并且程序按原样运行时，它可以工作。但是当放入一个函数时，它会删除-创建Found文件夹，但无法在其中创建文件。

#!/bin/bash

search(){

founddir=$(pwd)/Found

#---------gets inputs
echo "Enter the name of the directory:"
read searchdir
echo "Enter the keyword: "
read keyword

#-----this if statement checks if there are matching files
if grep -q -lr $keyword "$(pwd)/$searchdir"
then

    rm -rf Found 
    #removes old Found file, we're running this over and over it becomes more convinient to automate it this way. will be removed later
    mkdir Found 
#creates found file folder

    grep -q -lr $keyword "$(pwd)/$searchdir" | while read -r dir ; do 
        #------creates filepath to use in touch command, UNCERTAIN if it manages to
        file="$founddir/found_$(basename $dir)"
    enter code here
        #should create a file but does not
        touch $file

        #cant cp contents because file is not created
        cp -p $dir $file

    done

    echo "Files were copied to the Found directory!"

else
echo "Keyword not found in files!"
fi

}
search

我们已经尝试在变量声明中添加/删除引号，但似乎没有帮助。
