Question

为什么linux cp -r -a -R -P命令不能复制目录结构？

/tmp/backupTemp目录是存在的 但是/tmp/backupTemp/etc/rc.d不存在为什么不能自动创建却报错了？[qyj@A ~]$ sudo cp -a /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d/rc.localcp: cannot create regular file `/tmp/backupTemp/etc/rc.d/rc.local': No such file or directory[qyj@A ~]$ sudo cp -a /etc/rc.d/rc.local /tmp/backupTemp/rc.local[qyj@A ~]$ sudo cp -P /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d/rc.localcp: cannot create regular file `/tmp/backupTemp/etc/rc.d/rc.local': No such file or directory[qyj@A ~]$ sudo cp -r /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d/rc.localcp: cannot create regular file `/tmp/backupTemp/etc/rc.d/rc.local': No such file or directory[qyj@A ~]$ sudo cp -R /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d/rc.localcp: cannot create regular file `/tmp/backupTemp/etc/rc.d/rc.local': No such file or directory[qyj@A ~]$ sudo cp -p /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d/rc.local

Answer 1

mkdir -p /tmp/backupTemp/etc/rc.d
cp -p /etc/rc.d/rc.local /tmp/backupTemp/etc/rc.d
递归是指创建源目录的结构，而不是自动创建目的目录
比如 cp -Rp /etc /tmp/backupTemp

cp 没有实现mkdir的功能吗？

没有这种参数，必须先mkdir创建
