2.测试单独模拟执行脚本中的find + rm指令
[root@edbnode1 ~]# /bin/find /enterprisedb_backup/postgresql/ -mtime +7 -exec /bin/rm -rf {} ;
/bin/find: `/enterprisedb_backup/postgresql/network-scripts': No such file or directory
[root@edbnode1 ~]# echo $?
1
[root@edbnode1 ~]# ls /enterprisedb_backup/postgresql/
[root@edbnode1 ~]#
可以看到find操作的确返回了错误的结果，但查看数据备份目录发现，iptables文件及network-scripts目录已经正确删除
3.由于数据已经正确删除，因此我们开始怀疑是由network-scripts目录删除后，find继续尝试删除此目录下其它文件，导致出不“No such file or directory”的错误，因此需要于进一步证实此猜想，重新执行以上“第1步”中的数据环境模拟，并执行以下操作，主要是将rm转换成ls以展现整体运行过程：
[root@edbnode1 ~]# cp -rcp /etc/sysconfig/network-scripts/ /enterprisedb_backup/postgresql/
[root@edbnode1 ~]# cp -rcp /etc/init.d/iptables /enterprisedb_backup/postgresql/
[root@edbnode1 ~]# /bin/find /enterprisedb_backup/postgresql/ -mtime +7 -exec /bin/ls {} ;
