following sections: Text effects (poetry), problems (question), problem options (Bakans), Answers (answer), and hints (tips). These are stored in the shell array (girlLove.txt file) and are one by one corresponding relationships that are displayed in the main program girllove.sh through a while loop. The specific contents of the above sections can be set in the GirlLove.txt file, set the number of options and the user's screen, if the reader display

, because a process started with Telnet shuts down as the Telnet process shuts down. So we can use some UNIX commands to do it without shutting down.Use the following command:Nohup startweblogic.shIf you want to monitor standard output you can use:Tail-f Nohup.out When you run a program in the background, you can use the Jobs command to view the status of the background job. To use the FG command with parameters to switch background jobs of d

Source:Http://www.limodev.cn/blogContact information of the author: Li xianjing As a Linux programmer, working on a terminal (programming) in most cases may be more convenient. The server is in the data center and everyone is connected to the same server. The local machine runs a terminal (such as securecrt) in windows, which is a typical configuration. If the developed software does not contain a GUI, the

Do you often encounter situations where you connect to a Linux/unix machine via SSH or terminal putty, execute a program, a script, or a command, but now you need to close the SSH or terminal, because that program, script, or command is running, Once you close without doing any processing this process will be closed to

': main () The first print is T1 and main, and the second one is the main2. After talking to others, I thought this code should be considered a bad code, but was told that this difficult to understand the code is generated by object-oriented programming and product iteration, when invoking a new module, do not need to know his internal implementation principle, only need his parameters and return, Then if you want to expand him, just expand the interface directly.But I still don't qui

Serial port terminal program made of stc11f04 single-chip microcomputer. Similar to the Telnet command of a vswitch. Due to the rush of time, only a few simple commands are implemented. HelpLedbench onLedshortoffLed2_onLed2_off For example, enter? Enter the time command to query the current time in the microcontroller. You can enter led1_on to light up led1 on the board. Enter led1_off to extinguish le

Background: When you use ssh to manage servers, unexpected network disconnection and disconnection often occur. When the network is disconnected, the terminal is disconnected, if there is a program running on the front end or the current operation is very important and cannot be terminated at this time, the consequences may be very serious. At that time, you would like to cry, maybe some people say you can

For example, the following section of the source code (the source code is Cay S. Horstmann "Java Core Technology Volume 1: Fundamentals (10th edition English)" in the fifth chapter of the source):Package abstractclasses;Import java.time.*;compile with Javac.Then use Java and find always prompt "error: The main class could not be found or could not be loaded"This is a very strange question.The solution to the problem was later found to be simple:1, first in the source code directory under the ope
