Process Environment Variables Viewer

Python script for pretty-printing the environment variables for one or more processes.

Requirements

• Python 3
• psutil library

Setup

Ensure you have Python 3 installed:

python3 --version

Install the psutil package:

pip3 install psutil

Install

The easiest way to use this script is install it to a location on your path $PATH, e.g. /usr/local/bin (sudo or admin access may be required):

curl -sLf --retry 3 --tlsv1.2 --proto '=https' 'https://raw.githubusercontent.com/DopplerUniversity/process-env-vars/main/process-env-vars.py' | sudo tee /usr/local/bin/process-env-vars &>/dev/null
sudo chmod +x /usr/local/bin/process-env-vars

Then test by running:

process-env-vars --help

Filtering and matching rules

• All process name-based filters are case sensitive
• All arguments except --json support multiple instances, e.g. --pid 58327 --pid 58325
• Using --pid, --name (or a mix of both) short-circuits --filter and --ignore
• Using --username takes precedence over all other filters

Usage

Note:

• Some processes require sudo or admin access to fetch their environment variables
• Zombie processes do not return environment variables

Below are the most common usage examples for finding and filtering the process list:

Filter by user:

process-env-vars --user rb

Match using process ID:

process-env-vars --pid 58325

Match using multiple processes by ID:

process-env-vars --pid 58327 --pid 58325

Filter with exact match for process name:

process-env-vars --name Figma

Filter by exact process name:

process-env-vars --name figma_agent

Find processes where process name contains the supplied value:

process-env-vars --filter figma

Find processes where process name contains either of the supplied values:

process-env-vars --filter Figma --filter figma

Ignore processes where process name contains the supplied value:

process-env-vars --ignore Chrome

Ignore processes where process name contains either of the supplied values:

process-env-vars --ignore Chrome --ignore Electron

Output to JSON format:

process-env-vars --filter Electron --json
