Proc Signals under Process Management
In Linux, process management is a fundamental part of the system which involves creating, scheduling, terminating and coordinating the execution of processes. One crucial aspect of this is proc signals or process signals.
Process signals are a form of communication mechanism in Unix and Linux systems. They provide a means to notify a process of synchronous or asynchronous events. There are a variety of signals like SIGINT, SIGSTOP, SIGKILL, etc. available which can be sent to a running process to interrupt, pause or terminate it.
For instance, to send a SIGSTOP signal to a process with a PID of 12345 you would use kill command in terminal as follows:
kill -SIGSTOP 12345
This will suspend the execution of the process until a SIGCONT signal is received.
Understanding proc signals is essential for comprehensive process management and resource allocation in Linux.
