The purpose of this paper is to review the function, definition, nesting, deletion, terminal call, return value, parameter passing of shell functions.Knowledge Reserve function: That is Functions , a set of independent code modules that implement a common function (usually inside variables, variable parameters) are encapsulated together and given a name; When used, the whole code can be called directly by the given function name. Function

Exchange server2013 Series 7: high availability deployment of Client Access Servers Du Fei In the previous article, we introduced the High Availability Technology of client access servers. From this article, we will look at a detailed high availability deployment solution. First, let's take a look at our server list: No. Service name IPAddress Function 1 Hyv01 IP: 10.41.3.6

characters or spaces, this command I use a lot:CodeWhen formatting code is reviewed, spaces of blank lines and trailing spaces of lines are deleted.(7) Learn to combine the T command T // till means, this is one of my favorite commands DT "// delete In-row until", "Do not delete CT) // change in-row ),) do not delete ...... (8). Learn how to mix X and X to delete forward and backward characters, respectively.(9).: RD deletes row R. 3. Search

N/2-down adjustment in front of the heap, and the complexity of each adjustment time are O (logn). Two operation times added or O (N * logn). Therefore, the time complexity of heap sequencing is O (N * logn). STL also implements the related functions of the heap, you can refer to the "four heap heap of STL series". Note 1 As a data structure, it is best to use classes to encapsulate their data and methods so that they are easy to operate and understa

Oracle Learning Starter Series VIINetwork Management and ConfigurationWe learned about patterns and users, including pattern definitions and the role of patterns. In this article, I look at the network management and configuration in the Oracle database, but this seems to have no inheritance from the previous article.Ok, actually ... we're going to go down here.The network configuration of the database is relatively basic but also very important, if a

Contains the schema definition and the role of the pattern.Let's take a look at the network management and configuration in the Oracle database. It seems that this article and the previous article did not inherit AH. How does that look? Ok, in fact ... we're going to go down. The network conf

Interpretation of the Shader Series 7 written by CG in Unity -- diffuse reflection and unityshader If the content of the previous series of articles is too long and interesting, I am sorry. Due to the time, the mixed content has not been completed yet. I will try again later. Now I am beginning to discuss reflection content.Refraction and reflection In the physic

information about a U.S. customer, then we can create a view, each time just query the U.S. customer information, as long as the view name query on it! Similarly, views need to be defined and queried first. SQL is as follows:1 CREATE VIEW usa_cusomers2 as 3 (4 SELECT * from 5 sales.customers6 WHERE country= ' USA ' 7)After the definition is complete, execute the SQL, then the command is created, a

starts when the player in the No. 0 grid, Board[0] or 0, no impact:Do {The code checks the ladder or snake and then moves through the dice. And then a round of loops ends.The loop condition is the same as the previous one, but this time, when the loop condition is only completed the first cycle will be the first calculation. For this game, the Do-while cycle is more appropriate than the while period. On the Do-while loop, when the loop condition is determined squre but on the blackboard, he sta

Android RakNet Series 7-thread and server statistical test, androidraknetIntroduction A thread is a single sequential control flow in a program. A relatively independent and schedulable execution unit in a process is the basic unit for Independent System Scheduling and CPU allocation, which refers to the scheduling unit of the running program. It is called multithreading. The thread is re-encapsulated in Ra

:11:2: weight declared and not usedScope) The variable defined in the function is a local variable, which is only visible in the function. Defined in a code block (for example{...CODE...}) Is also a local variable, except for the code block. Variables defined outside the code block and outside the function are package variables or global variables, they can be accessed by multiple files in the same package under the same directory (because one directory in go can only define one package, but

System refactoring requires that every step of code modification cannot change the external behavior of the software. Therefore, all methods in system refactoring are equivalent changes of code. The reconstruction process is like performing an equivalent transformation of the formula step by step in a mathematical problem. After a series of equal transformation, although the final result is different from the original form, it can be obtained through
