Bash - How to loop through sub directories and copy in a file
提问by ThePerson
I'm new to coding in bash.
我是 bash 编码的新手。
I'm trying to create something which will loop through all subdirectories, and within each one it should copy a file to that directory.
我正在尝试创建一些将遍历所有子目录的东西，并且在每个子目录中它应该将一个文件复制到该目录中。
So for example, if I have the following directories
例如，如果我有以下目录
/dir1/
/dir2/
/dir3/
...
...
/dirX/
And a file fileToCopy.txt
还有一个文件 fileToCopy.txt
Then I want to run something which will open every single /dirXfile and put fileToCopy.txtin that directory. Leaving me with:
然后我想运行一些将打开每个/dirX文件并放入fileToCopy.txt该目录的东西。留给我：
/dir1/fileToCopy.txt
/dir2/fileToCopy.txt
/dir3/fileToCopy.txt
...
...
/dirX/fileToCopy.txt
I would like to do this in a loop, as then I am going to try to modify this loop to add some more steps, as ultimately the .txt file is actually a .java file, I am wanting to copy it into each directory, compile it (with the other classes in there), and run it to gather the output.
我想在循环中执行此操作，然后我将尝试修改此循环以添加更多步骤，因为最终 .txt 文件实际上是一个 .java 文件，我想将其复制到每个目录中，编译它（包含其他类），并运行它以收集输出。
Thanks.
谢谢。

for i in dir1, dir2, dir3, .., dirN
do
cp /home/user1068470/fileToCopy.txt $i
done
Alternatively, you can use the following code.
或者，您可以使用以下代码。
for i in *
do # Line breaks are important
if [ -d $i ] # Spaces are important
then
cp fileToCopy.txt $i
fi
done

Finds all directory under the current directory (.) and copies the file into them:
查找当前目录 (.) 下的所有目录并将文件复制到其中：
find . -type d -exec cp fileToCopy.txt '{}' \;
