One, why to make the program line The programs we calculate are very long periods, usually in hours or even one weeks. The environment we use is remotely connected to a Japanese Linux server using Putty. So running a program in the background has the following three benefits: 1: Our side whether the shutdown does not affect the Japanese side of the program running. (Not like before, we this network a discon

1. automatically run the program at startup After Linux is loaded, it initializes the hardware and device drivers, and then runs the first process init. Init starts other processes based on the configuration file. Normally, the modification is placed in/etc/rc or/etc/rc. d or/etc/rc ?. The script file in the d directory can enable init to automatically start other programs. For example, to edit the/etc/rc.

Although the old left blog is a Wordpress program, I have to say that the wp program is even one of the great programs, but the resource occupation problems are still relatively poor. If you have used the WP program to create a blog, you should know that when the website traffic reaches hundreds of times, the average host CPU will exceed the threshold, and even the host will be suspended. Generally, the CPU limit of host products is 5-10%, so it is ea

Linux controls the order in which two programs are started: service1 and service2. service2 depends on service1, that is, it can be started only after service1 is started. if the service1 application occupies a specified tcp port, the following script can perform this operation: echo quot; service1start... quot ;...

matching processing function can be resolved.When an executable program is launched in the shell, a new process is created that takes the desired execution context by overwriting the process environment of the parent process (that is, the shell process) and emptying the user-state stack.command-line arguments and environment variables are passed through the shell to Execve,excve through the system invocation parameters, passed to Sys_execve, and finally Sys_execve copied when the new process st

How to view the libraries that Linux programs or processes use (Shared library dependencies). View shared library dependencies for an executable program To find a library of specific executable dependencies, you can use the LDD command. This command invokes the dynamic linker to find the program's library file dependencies. $ ldd/path/to/program Note that it is not recommended to run LDD for any unt

Compile open-source programs using eclipse in Linux In Linux, we can use eclipse to compile and debug open-source programs. In this way, we do not need to use the command line all the time. It is very convenient. We will take gxemul as an example to introduce it: 1. In http://gxemul.sourceforge.net/download gxemul,
