One of the most powerful features of the kernel is process management, and for system administrator, this part of proficiency plays a decisive role in the tuning of systems. Now let's take a look at Linux's process management tools, some basic

1. Creation of processesThere are four types of functions that create sub-processes under Linux: System (), fork (), exec* (), Popen ()1.1. System functionsPrototype: #include int system (const char *string); The system function executes the

There are 5 states of processes on Linux:1. Running (running or waiting in the running queue)2. Interrupt (dormant, blocked, waiting for a condition to form or receive a signal)3. Non-interruptible (receive signal does not wake up and not run,

1.1 What is a memory leak?A situation in which a program fails to release memory that is no longer in use due to negligence or error. A memory leak does not mean that there is physical disappearance, but that the application allocates some memory,

What is a process?A process is a process that loads a binary file into an individual that is formed in memory.In our Linux system, the system only recognizes binary files, so if a system wants to run normally, it must start some binaries to form a

There are many tools on Linux for system process management, such as PS, Pstree, pidof, pgrep and so on, but they all just capture the process state information of the previous second that the current administrator entered the command and hit enter,
