Error cp: cannot create regular file "": no such file or directory
提问by Alwyn Gardner
I am trying to move files that have been searched for from a source folder into a target folder and make them read only in the process, below is my current code, copyfile() is a subroutine that iterates the process for all files in the source folder.
我正在尝试将已从源文件夹中搜索到的文件移动到目标文件夹中，并使它们在该过程中只读，下面是我当前的代码，copyfile() 是一个子例程，它对源中的所有文件进行迭代文件夹。
#!/bin/bash
copyfile()
{
ls -l "$f"
read -p "Copy y/n? " yn
if [ "$yn" == "y" ]
then
cp "$f" ""
else
echo $f skipped
fi
}
if [ -d ] # source folder
then
echo
else
echo This directory does not exist
fi
if [ -d ] # target folder
then
echo Directory Exists
else
mkdir
echo created
fi
for f in /*
do
echo "file is $f"
copyfile "$f"
done
I currently have not managed to get the permission change to work for the copied files (when they have done so with different versions of the code).
我目前还没有设法获得权限更改以用于复制的文件（当他们使用不同版本的代码这样做时）。
Any help is much appreciated in advance.
任何帮助都非常感谢提前。

Have your function like this:
有这样的功能：
copyfile() {
ls -l ""
read -p "Copy y/n? " yn
if [ "$yn" == "y" ]
then
cp "" ""
chmod 644 ""
else
echo " skipped"
fi
}
and call it like this:
并这样称呼它：
for f in /*
do
echo "file is $f"
copyfile "$f" ""
done
