In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels—such as those of Unix, macOS and Windows—to uniquely identify an active process. This number may be used as a parameter in various function calls, allowing processes to be manipulated, such as adjusting the process's priority or ...
However, if the parent process lingers in collecting the child's data (or fails to do it at all), the system has no option but keep the child's pid and termination data in the process table indefinitely. Such a terminated process whose data has not been collected is called a zombie process, or simply a zombie, in the UNIX parlance. The name is ...
POSIX defines the following options: [1]-c Treat the file as a mount point.-f Only report processes accessing the named files.-u Append user names in parentheses to each PID. psmisc adds the following options, among others: [2]-k, --kill Kill all processes accessing a file by sending a SIGKILL. Use e.g. -HUP or -1 to send a different signal.-l ...

pstree is a Linux command that shows the running processes as a tree [1] [2] [3]. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...

U.S. mortgage rates rose this week to the highest level since July. The benchmark 30-year fixed rate loan rate rose to 6.91% from 6.85% last week, according to mortgage giant Freddie Mac. The ...
The first process created in a PID namespace is assigned the process ID number 1 and receives most of the same special treatment as the normal init process, most notably that orphaned processes within the namespace are attached to it. This also means that the termination of this PID 1 process will immediately terminate all processes in its PID ...
