To exit select, you can use break or exit the entire script. Select var [in list] do commanddone is the same as for. if in list is omitted, it is replaced by a command parameter. The select prompt set for the PS3 is generally set as the required prompt statement. # Command menu
consumer electronics are simply divided into three levels for pricing: Good/better/best. The only difference between different levels is the storage capacity. Ipod, iPad, and iPhone all follow this pattern. Even if there is a deviation, the reason is well understood. For example, the cost of a standard iPad with Wi-Fi is USD 499/599/699, and the storage capacity is 16/32/64 GB. If you want an iPad with a built-in 3G function, you need to add $130 to the standard iPad price and provide two simpl
wireless connection to adhoc bring great convenience to consumers.Now the PS3 game console supports Bluetooth controllers, which allows consumers to have devices that can display game images anytime, anywhere. Similarly, Media Center device manufacturers will benefit from allowing consumers to control and view different video content wirelessly on any display device at home.For enterprise applications, the absence of a video connection means that ted
The content of script a. sh is:
Set-x
Echo "$ PWD" execution script result: ++ echo/home/yanwenjie/bashtest
/Home/yanwenjie/bashtest
The-x option returns the command line result after parameter replacement, command replacement, and other command line processing steps. The x option prints + at the beginning of each line (but I don't know why I printed two). This can be customized. It is the value of the built-in shell variable PS4. You can modify this symbol by modifying the PS4 value. For examp

A heavyweight tool is mainly an IDE with more complete functions, such as Visual Studio, which is mainly used in large-scale projects in actual work. Lightweight tools are some editors that can better support programming, such as emeditor and editplus. They are mainly personal small projects after work or modifications to files.

Next, let's look at the multi-threaded 3D engine solution proposed by ID soft on siggraph2008.The engine structure of the PS3 is used as an example, which is quite different from that of the PC.
