默认cp 只是copy文件，会忽略路径，如果要带上cp文件的路径，则需要cp 加上 --parents 参数

示例：

[root@Salt_Master ops-opermanage]# git diff --stat --name-only  fe9ffa4474447095f34c39c3bb911fd899cdbfb2 33ebed138d599f5bf5df12259258628b5a23449d

ops-opermanage/pom.xml

ops-opermanage/src/main/java/com/wzhl/common/utils/RandomUtil.java

ops-opermanage/src/main/java/com/wzhl/project/controller/FinanceAdminController.java

ops-opermanage/src/main/java/com/wzhl/project/domain/FdMemberShellLogModel.java

ops-opermanage/src/main/java/com/wzhl/project/mapper/FdTransactionsResultMapper.java

ops-opermanage/src/main/java/com/wzhl/project/mapper/FinanceAdminMapper.java

ops-opermanage/src/main/java/com/wzhl/project/rep/CodeMsg.java

ops-opermanage/src/main/java/com/wzhl/project/rep/R.java

ops-opermanage/src/main/java/com/wzhl/project/service/FinanceAdminService.java

ops-opermanage/src/main/java/com/wzhl/project/service/impl/FinanceAdminServiceImpl.java

ops-opermanage/src/main/resources/mybatis/fddb/FdTransactionsResultMapper.xml

ops-opermanage/src/main/resources/mybatis/system/FinanceAdminMapper.xml

把这些文件cp到指定目录，路径要保持不变，可以这样做

for i in `git diff --stat --name-only  fe9ffa4474447095f34c39c3bb911fd899cdbfb2 33ebed138d599f5bf5df12259258628b5a23449d`;do

cp --parents  $i /root/shitian/change

done
