2022年11月11日 · pstree command in Linux is used to display running processes owned by root or specific users in a tree-like structure. A tree is a hierarchical data structure consisting of n0des (processes) and a list of references to other nodes (sub-processes).

2018年10月7日 · You could use a program called Process Monitor.This program allows you to do what you want. Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity.

2017年4月28日 · pstree can be used to print all the ancestors of a process. But latest Linux distributions uses systemd instead of init. Example: pstree -p -s 6206 will give following output. systemd(1)───lightdm(1066)───lightdm(1191)───upstart(1360)───gnome-terminal-(5222)───bash(5229)───cpu-print(6206)

2018年10月15日 · Do not parse pstree. On Linux, the main method to enumerate processes – the source of this information – is listing subdirectories of /proc with numeric-only names. Each such directory represents a process and its name is the PID.

2015年6月17日 · The pstree is a very good solution, but it is a little bit reticent. I use ps --forest instead. But not for a PID (-p) because it prints only the specific process, but for the session (-g). It can print out any information ps can print in a fancy ASCII art tree defining the -o option.

Tools like pstree use /proc to gather information, so read /proc/<PID>/cmdline. It's a bad luck if the information is truncated there. But it may be that you hit the limit of your pstree implementation only. In my case /proc/<PID>/cmdline was not trimmed when I crossed the limit in pstree.

2019年1月14日 · On Linux, tree and pstree commands show tree-like hierarchy of directories and processes respectively. Their output usually includes the characters | and _ which are used to draw the tree structure. When I use PuTTY to ssh into my instances (Ubuntu 18.04 and Centos 7), the output show these characters as â.

Is there any utility out there for linux that will give me a PStree with memory use per process? I guess it's possible in theory to grab a pstree with pids, then comb ps itself for the memory use for that pid and merge them together via code, but I would be amazed if someone hasn't done this already before I reinvent the wheel.
