Linux copies all contents under one folder or folder to another folder

1. Copy all the contents in one folder to another folder

cp -r /home/packageA/* /home/cp/packageB/
或
cp -r /home/packageA/. /home/cp/packageB/
这两种方法效果是一样的。

Method example:

2. Copy a folder to another folder

cp -r /home/packageA /home/packageB

运行命令之后packageB文件夹下就有packageA文件夹了。

Method example:

3. Delete a folder and all the files below it

rm -rf /home/packageA

-r表示向下递归，不管有多少级目录，一并删除
-f表示直接强行删除，不作任何提示的意思

4. Move a folder to another folder

mv /home/packageA /home/packageB/
或
mv /home/packageA /home/packageB
这两种方法效果是一样的。

5. Move all the contents in one folder to another folder

mv /home/packageA/* /home/packageB/

I'm just a porter of knowledge, new to Linux.
