A signal (signal) is a software interrupt that provides a way to handle asynchronous events and is the only asynchronous communication between processes. In a Linux system, the subsequent signaling mechanism is extended according to the POSIX

http://blog.csdn.net/eager7/article/details/8290937We run the following command to see a list of supported signals from Linux:$ kill-l1) SIGHUP 2) SIGINT 3) Sigquit 4) Sigill 5) SIGTRAP 6) SIGABRT 7) Sigbus 8) SIGFPE 9) SIGKILL) SIGUSR1) SIG SEGV)

################### # # Process Definition # # ###################Whenever an event is triggered, the system defines it as a process and gives the process an ID, called the PID.Process is the work that the CPU does not complete*) distinguish

In some cases, we don't want our shell scripts to be interrupted at runtime, such as when we write shell feetThis is set to a user's default shell, so that the user can only do one job after entering the system, such as database backup, IWe do not

Under Linux, each signal's name begins with the character SIG , and each signal corresponds to a digital encoding, which is defined as a positive integer in the header file signum.h . Signal name definition

Orphan process and daemon processThrough the previous study we learned how to create a process through the fork () function and the vfork () function. Now let's go into two special processes: The orphan process and the daemon.I. The orphan process1.

Signal () function to describe Linux functions in detail A signal (signal) is a interprocess communication mechanism that provides an application with an asynchronous software interrupt that gives the application the opportunity to accept

Optical fiber access Network is a set of physical entities and solutions that rely on optical fiber to extend the user's port, and FTTH all-optical access network based on Epon/gpon technology is the only way to develop the optical fiber access

Broadband network access switches usually need to connect directly with the user terminal, once the user terminal infection worm, virus attack will seriously consume bandwidth and switch resources, and even network paralysis, this phenomenon in the

When using Linux, it is often desirable that some command results not be displayed in the foreground, such as SH scripts, time-consuming commands, etc.In general, use & to run the command results in the background, such as SH test.sh, script

1. From circuit switching technology to group Switching Technology The most basic application of circuit switching is that a signal occupies one line. This physical line is occupied by this signal until the electronic switch switches to another
