ramtree

A memory viewer for the terminal, built on the same interface as disktree. Every process is grouped under the one that started it, and each group’s size includes everything beneath it, so a browser and its dozens of helpers show as one line you can open. Mark any number of processes and ask them to close, or force-kill them, behind a confirmation that shows where each one sits in the tree.

Any platform

cargo install ramtree

Without elevation, Windows hides the memory of services and other users’ processes, and macOS hides root’s; they count as zero, and the header says how many. Run it elevated to see more.

In the terminal

See what’s using your RAM, and end it safely.

Processes are grouped under whatever started them, so a browser and its dozens of helpers show as one line you can open.

 All processes  —  25.3 GB, 425 processes  (RAM 51.2 GB of 63.1 GB in use)  (148 unreadable)

Enter: Open a process group
Backspace: Go up
Space: Mark, then move on
d: Ask marked processes to close
D: Force kill them
r: Refresh in place

The screen from ramtree’s README, from a run on a Windows PC. Each line ending in a backslash is a process and everything it started, counted together.

Capabilities

What it does.

Engineers who want ramtree to fit into the workflow they already have.

01
Processes grouped under their parents, with each group sized by everything it started
02
Mark several processes, then ask them to close or force-kill them, after a confirmation that shows each one’s place in the tree
03
Won’t end its own terminal, and checks start times so a reused PID is never the wrong target
04
Refreshes in place after a kill without losing your position
