Basic usage of the find command

Compared with the non-real-time SEARCH command like locate, the find command greatly increases the convenience and accuracy of our search; in addition, it can easily help us find and delete large files and specific types of files, especially when there are more than a few small broken files, it is extremely convenient ....

-User username: searches for files whose owner is xx.
-Group: Find the xx file of the group
-Uid useruid: Find the uid File
-Gid groupid: Find the file with the gid number

-Type f: Common File
-Type d: directory file
-Type l: Symbolic Link file
-Type s: Socket File
-Type B: block Device File

-Size + 10 M: Files larger than 10 M
-Size + 10 k: Files larger than 10 k
-Size + 1G: Files larger than 1G
-Size-1G: file smaller than the file size

Search by Time

In units of one day
-Atime: Access time
-Mtime: modification time
-Ctime: Change Time
In minutes:
-Amin: Access time
-Mmin: modification time
-Cmin: Change Time

Search by permission

-Perm + mode:
-Perm + 600: Other permissions of the owner group should be successful if one match exists. 600 indicates three objects, which are used on CentOS7 of the 6 owner./600
-Perm-600: each object must have the specified permissions at the same time. The three objects must be set up at the same time. For example,-003 indicates that other users must have the write and execution permissions.

Combination condition search

-A: corresponds
-O: or
-Not: non
! : Non

-Delete: delete the searched file.
-OK command {}\; execute the command specified by command on the searched file, interactive

Action transmission mode after finding
