一、通过文件修改时间查询

1.查找5分钟前的文件

在这里插入代码片

[root@tianyi ~]# find /etc -mmin +5 |head |nl
     1	/etc
     2	/etc/pear.conf
     3	/etc/NetworkManager
     4	/etc/NetworkManager/conf.d
     5	/etc/NetworkManager/conf.d/99-cloud-init.conf
     6	/etc/NetworkManager/NetworkManager.conf
     7	/etc/NetworkManager/dnsmasq.d
     8	/etc/NetworkManager/system-connections
     9	/etc/NetworkManager/dnsmasq-shared.d
    10	/etc/NetworkManager/dispatcher.d
[root@tianyi ~]# 

二、通过文件权限查找

1.创建不同权限文件夹

[root@tianyi ~]# mkdir -m 777 /data/test1
[root@tianyi ~]# mkdir -m 406 /data/test2
[root@tianyi ~]# mkdir -m 101 /data/test3
[root@tianyi ~]# 

2.查找其他人有写的文件夹

[root@tianyi data]# find -perm -002
./test1
./test2
[root@tianyi data]# ll -ld ./test1
drwxrwxrwx 2 root root 4096 Dec 29 11:05 ./test1
[root@tianyi data]# ll -ld ./test2
dr-----rw- 2 root root 4096 Dec 29 11:05 ./test2

3.查找拥有人、拥有组、其他人都有写权限文件夹

[root@tianyi data]# find -perm -222
./test1
[root@tianyi data]# ll -ld ./test
drwxr-xr-x 2 root root 4096 Dec  1 00:48 ./test
[root@tianyi data]# ll -ld ./test1
drwxrwxrwx 2 root root 4096 Dec 29 11:05 ./test1
[root@tianyi data]# 

4.查找拥有人有读权限的文件夹

[root@tianyi data]# find -perm -600
.
./test1
./test
./passwd
./scrips
./person.txt
[root@tianyi data]# 

三、查找文件并处理

1.创建备份文件夹

[root@tianyi data]# mkdir /backup

2.备份以conf的文件

[root@tianyi backup]# find /etc -name *.conf -exec cp -a {} /backup/ \;
cp: not writing through dangling symlink '/backup/yum.conf'
cp: '/etc/authselect/nsswitch.conf' and '/backup/nsswitch.conf' are the same file
[root@tianyi backup]# head -n 10
^C
[root@tianyi backup]# ls |head
00-base.conf
00-dav.conf
00-keyboard.conf
00-lua.conf
00-mpm.conf
00-optional.conf
00-proxy.conf
00-systemd.conf
01-cgi.conf
05-redhat.conf
