Strace is commonly used to track system calls and received signals when a process executes. In the Linux world, processes cannot directly access hardware devices, and when a process requires access to a hardware device (such as reading a disk file,

The scheduling priority is an integer value, from 20 (highest priority) to +20 (lowest priority). By default, the bash shell starts a process of 0 for all priority processes! Nice command: nice-nThe nice command can set the priority when the

the following command looks at the list of top processes in descending order of RAM and CPU: [email protected]~]#PS-eo PID,PPID,CMD,%MEM,%CPU--Sort=-%mem |HeadPID PPID CMD%MEM%CPU1 0/sbin/init0.1 0.0 2 0[Kthreadd]0.0 0.0 3 2[migration/0]0.0 0.0 4

These processes are dead, but no system resources are released, including memory and some system tables, which can cause system problems if there are many such processes. The process state that is seen with Ps-el is a zombie process if it is Z.

Sometimes the system administrator may only be concerned about which programs are running on the system and don't want to know which processes are running. Because an application may need to start multiple processes. So in the same situation, the
