psinfo 0.1.1

Rich terminal process viewer

psinfo

A rich terminal process viewer. Search, filter, and watch running processes with colour-coded output.

psinfo is for when you have a specific question — "what's on port 8080", "how much memory is Chrome using across all its helpers", "is nginx running and what's it doing" — and want a clean answer without launching a full process manager or constructing a ps aux | grep | awk pipeline.

Install

pip install -e .
# or, to install as an isolated CLI tool:
pipx install .

pipx is recommended for CLI tools — it installs into an isolated environment and puts psinfo on your PATH. Install it with brew install pipx or pip install pipx.

Usage

psinfo <name>            search by process name or command
psinfo -u <username>     all processes owned by a user
psinfo -p <port>         process listening on a port
psinfo -P <pid>          single process by PID

Flags

Flag	Short	Description
--watch [N]	-w	Live refresh every N seconds (default: 2)
--sort cpu|mem	-s	Sort order (default: cpu)
--tree	-t	Group results by process tree hierarchy

Flags compose freely:

psinfo nginx -w
psinfo python -w 5 -s mem
psinfo slack -t -w

Output

Card view (default)

Each matching process is shown as a panel. The highest-CPU process gets a green border. Metrics are colour-coded: green (< 10%), orange (≥ 10%), red (≥ 50%).

Tree view (-t)

Results are grouped by parent/child relationships. Parent nodes show their own CPU plus a ∑ total across the whole subtree.
