Under Linux, each file and directory has its own access rights, which determines whether the user can access files or directories and how to access them. One of the most well-known files or directories may have three permissions, read, write, and perform operations, which are not explained in detail here.

LINQ can be used to query and transform strings and string collections. It is especially useful for semi-structured data in text files. LINQ queries can be used in conjunction with traditional string functions and regular expressions.

In practice, it may be that a simple, crude line might not be the best result we want, for example, if you want to display the original data points on a graph, if your service interface is not Dubbo, such as a Rest API interface based on spring MVC implementation, Then there is no use of the above Dubbo to help you do the useful log function. But spring MVC implements the above log requirement method is also many, the typical example can use the Handlerinterceptor such interceptor, only need to implement this interface, Then add the logging function to the implementation class: We can get all the data you want by handler this parameter, plus request and response two informative objects for you to use.

Now we switch users to DH user, try to delete the newly created file, found that it can be completely deleted. Then there is a problem, like the/tmp directory permissions should be set to "rwxrwxrwx", because it to allow any user can be created in this directory, delete, move files and other operations. But we have just seen, my DH users can delete the root user created in the Cur directory folder, then for the TMP directory, any user can delete the system service running temporary files (other users), then this is definitely not what we want.
