我在ubuntu機器上安裝了以下文件夾：
（方括號表示文件夾）

[main]
   |
   |--- [old]
   |      |
   |      |--- [thequick]
   |      |           |
   |      |           |--- [aaaa] --- some files
   |      |           |--- [bbbb] --- some files
   |      |           |--- [cccc] --- some files
   |      |           |--- [dddd] --- some files
   |      |           |--- some files
   |      |
   |      |--- [brownfox]
   |      |           |
   |      |           |--- [aaaa] --- some files

   |      |           |--- some files
   |      |---  ...
   |      |
   |      |--- [lazydog]
   |                  |
   |                  |--- [aaaa] --- some files
   |                  |--- [bbbb] --- some files
   |                  |--- [cccc] --- some files
   |                  |--- [dddd] --- some files
   |                  |--- some files
   |
   |--- [new]
          |
          |--- [thequick]
          |           |
          |           |--- [aaaa] --- some files
          |           |--- [bbbb] --- some files
          |           |--- some files
          |
          |--- [brownfox]
          |           |
          |           |--- [aaaa] --- some files
          |           |--- [bbbb] --- some files
          |           |--- some files
          |---  ...
          |
          |--- [lazydog]
                      |
                      |--- [aaaa] --- some files
                      |--- [bbbb] --- some files
                      |--- some files

我需要找到一種快速方法，將所有舊的 [aaaa]和[bbbb]文件夾替換為它們各自的新 [aaaa]和[bbbb]文件夾， 而又不影響任何其他舊的東西。

Answer 1

你可以做：

cd /main/old
find . -type d \( -name 'aaaa' -o -name '-bbbb' \) -exec cp -RfP {} ../new/{} \;

Answer 2

這是明確且非常標准的

cd main/old
for dir in `find . \( -name aaaa -o -name bbbb \) -a -type d`
do
    (
    cd ..
    if [ -d new/$dir ]
    then
        rm -rf old/$dir
        mv new/$dir old/$dir
    fi
    )
done
cd ../..
