In the/logs Directory, find and delete files whose changes were earlier than 5 days.
$ Find logs-type f-mtime + 5-exec rm {}\;

Find common files in the/var/logs directory that were modified seven days ago and ask them before deletion.
$ Find/var/logs-type f-mtime + 7-OK rm {}\;

You can use a certain file name pattern to match the file. remember to use quotation marks to cause the file name pattern. otherwise, matching and expanding will cause confusion of the find parameter.
$ Find.-name [A-Z] *-print

In the current directory, find the file with a permission of 755, that is, the file owner can read, write, and execute. other users can read and execute the file.
$ Find.-perm 755-print
