, you can use curly braces to differentiate, for example:echo "Hi, $as"It will not output "Hi, Hello Worlds", but output "Hi,". This is because the shell treats $as as a variable, and $as is not assigned a value, and its value is empty. The correct method is:echo "Hi, ${a}s"Example two:Tomcat logs are scheduled to be saved by date.#!/bin/shBaktime= ' Date +%y-%m-%d_%h%m ' #定义变量, get of course year, month, day, time, minuteCp/usr/local/tomcat/logs/cata
Dissolution effects are common in the game, such as in some myths or magical worlds, where some NPC characters will gradually disappear when the plot is needed. Even some of the more flashy ones, like burning the target with a flamethrower. These can all be used to dissolve the effect. This article is mainly to explain how the comparative basis of the dissolution effect, the implementation of the method is not unique, this article is only one of the

Coordinated Universal time (UTC): Coordinated worlds, also known as World standard Times, is known as Greenwich Mean Time (Greenwich Mean time,gmt). For example, the time difference between the Chinese mainland and UTC is +8, which is utc+8. The United States is UTC-5.Epoch (epoch) is defined as 0:00 midnight of January 1, 1970 of the Coordinated Universal Time (also UTC or Greenwich Mean Time or GMT).Calendar time is the number of seconds elapsed sin
When using HoloLens, the shell is made up of the world around you and holographic images from the system. We make this space a mixed world (mixed worlds). The shell contains a Start menu that allows you to place holographic images and applications in the world. When an application has been placed in the world, it will either be used as a 2D application or in the form of a model. This resource will always stay in its place, even if you leave the room a
users who have a slightly English base prefer to use the English interface system.However, the contradiction is also emergent: under the English system, how can normal display and input Chinese? Is there a solution for both worlds? Therefore, the author began to explore how to solve this problem.My perfect state is: the system and the application are all in English (System menu, application toolbar, default input method, etc.), and I need to read and
