Copy one file into every subdirectory
提问by Chris
I'm trying to cpone file: index.phpinto all subdirectories, and subdirectories of those subdirectories, and so on, so that every child directory of the root has index.php
我正在尝试cp一个文件：index.php进入所有子目录，以及这些子目录的子目录，等等，这样根的每个子目录都有index.php
I started with this:
我从这个开始：
for d in */; do cp index.php "$d"; done;
Which only worked for the top subdirectories. I tried to nest it in itself a few times like this:
这只适用于顶级子目录。我试着像这样将它嵌套几次：
for d in */; do cp index.php "$d"; for e in */; do cp index.php "$e";for f in */; do cp index.php "$f"; done; done; done
But that didn't seem to do anything
但这似乎没有任何作用

Try this :
尝试这个 ：
find . -type d -exec cp index.php {} \;
Note
笔记
-type dfind all dirs and sub-dirs
-type d查找所有目录和子目录

sputnick's answer is nice and simple. For the record, here is one way to do it with a shell function. You might want something like this if the operation is complicated or conditional.
sputnick的回答很好也很简单。作为记录，这是使用 shell 函数执行此操作的一种方法。如果操作复杂或有条件，您可能需要这样的操作。
t=$PWD/index.php
recurse () {
for i in */.; do
if [ "./$i" != './*/.' ]; then
(cd "./$i" && cp "$t" . && recurse)
fi
done
}
recurse
