The INIT program needs to read the configuration file/etc/inittab. Inittab is a non-executa

The init process number is 1 (ps-aux | less). From this point, we can see that the init process is the starting point of all processes in the system. After Linux completes the kernel boot, start to run the init program. The init program needs to read the configuration file/etc/inittab. Inittab is an unexecutable text file consisting of several lines of commands. Understand Runlevel: Runlevel is used to indicate the state of the system after the init p

Signal processing is a feature of Linux programs. Signal processing is used to simulate the interrupt function of the operating system. To use the signal processing function, all you have to do is fill out a signal processing function.1#include 2#include 3#include 4#include 5 6 intFlag =1; 7 8 voidFuncintSig)9 { Tenprintf"I get a signal!\n"); OneFlag =0; A } - - intMain () the { - signal (SIGINT
