pinspect — Linux Process Intelligence CLI

Fast, deep Linux process inspection and forensic intelligence tool that goes far beyond ps aux.

pinspect is an all-in-one terminal tool designed for systems engineers, SREs, and security investigators. It collects deep, actionable intelligence about running processes directly from native Linux /proc and kernel interfaces with zero external command dependencies, low overhead, graceful error recovery, and rich terminal and SIEM/EDR output formats.

📦 Installation

Install directly from PyPI:

pip install pinspect-cli

Or install with pipx (isolated environment):

pipx install pinspect-cli

Or run from source:

git clone https://github.com/Baba01hacker666/pinspect.git
cd pinspect
pip install -e .

⚡ Key Highlights

• Complete Process Visibility: PID, PPID, ancestry chain to PID 1, command line, arguments, executable, working directory, root directory (with chroot detection), start time, real/effective/saved/fs UIDs & GIDs, supplementary groups, session ID, process group, and TTY.
• Launch & Origin Intelligence: Automatically detects whether a process originated from systemd, cron, SSH, an interactive shell, Docker, Podman, Kubernetes, a supervisor (e.g. runsv, supervisord), or the kernel. Resolves systemd service unit names, unit files on disk, and container IDs.
• Security & Privilege Forensics: Decodes 64-bit Linux capability bitmasks (CapEff, CapPrm, CapInh, CapBnd, CapAmb) to named capabilities (CAP_SYS_ADMIN, CAP_NET_RAW), checks NoNewPrivs, Seccomp filters, AppArmor/SELinux contexts, SetUID/SetGID bits, executable SHA-256 hashes, and unlinked binary execution ((deleted) executables & memory mappings).
• Files & Sockets: Inspects open file descriptors, target classification (regular files, pipes, unix sockets, network sockets, anon inodes), permissions, file size, deleted files held in memory, and system-wide/per-PID network connections.
• Secret Redaction: pinspect env automatically discovers and masks sensitive secrets and credentials (*_TOKEN, *_KEY, *_SECRET, *_PASSWORD, AWS_*, DATABASE_URL, JWT tokens, and private keys).
• Process Hierarchy Tree: Visualizes process trees with color-coded states, CPU/memory stats, container badges, and ancestry lineages.
• Interactive TUI: Built-in interactive dashboard with live filtering, sortable columns, and detailed multi-tab views.
• SIEM / EDR Formats: Structured JSON output (--json), CSV export (--csv), wide (--wide), and quiet mode (--quiet).

📖 Command Reference

1. Process Listing (pinspect ps or pinspect)

Lists running processes with CPU, memory, origin, and state:

# Default process list
pinspect ps

# Filter by user or UID
pinspect ps --user root
pinspect ps --user 1000

# Filter by process name (regex)
pinspect ps --name "nginx|caddy"

# Filter by listening or connected network port
pinspect ps --port 8080
pinspect ps --listen

# Filter by systemd service name
pinspect ps --service ssh

# Filter for containerized processes only
pinspect ps --container

# Filter for processes running deleted executables or open deleted files
pinspect ps --deleted

# Sort options (cpu, mem, pid, user, name, age)
pinspect ps --sort mem --limit 10

2. Process Tree (pinspect tree)

Renders hierarchical process tree:

# Full system tree
pinspect tree

# Subtree rooted at a specific PID
pinspect tree 1234

# Highlight a specific PID in the tree
pinspect tree --highlight 1234

3. Detailed Process Inspection (pinspect show <PID>)

Displays comprehensive intelligence card for a single PID:

# Show identity, origin, CPU/mem stats, security, namespaces, ancestry
pinspect show 14847

# Include SHA-256 binary hash
pinspect show 14847 --hash

4. Open Files & Descriptors (pinspect files <PID>)

Inspects open FDs, targets, inode numbers, and deleted files:

pinspect files 14847

# Show only deleted files held open by process
pinspect files 14847 --deleted

# Filter by type (regular, socket, pipe, anon, char)
pinspect files 14847 --type socket

5. Network Sockets (pinspect network [PID])

Inspects TCP, UDP, and Unix domain sockets mapped to processes:

# All network sockets on the host
pinspect network

# Network sockets for a specific PID
pinspect network 14847

# Filter by port and protocol
pinspect network --port 443 --proto TCP --listen

6. Environment Variables (pinspect env <PID>)

Inspects process environment variables with automatic secret redaction:

# Redacted view (default)
pinspect env 14847

# Search variable names
pinspect env 14847 --filter TOKEN

# Unredacted view (explicit authorization)
pinspect env 14847 --show-secrets

7. Process Ancestry & Children (pinspect ancestry / pinspect children)

Inspects process lineage chains:

# Full ancestor chain from PID 1 / init down to the process
pinspect ancestry 14847

# Subtree of children and descendants
pinspect children 14847

8. Namespaces (pinspect namespaces <PID>)

Compares namespace inodes against host/PID 1:

pinspect namespaces 14847

9. Security & Capability Forensics (pinspect security <PID>)

Inspects Linux capabilities, Seccomp, NoNewPrivs, LSM, and file integrity:

pinspect security 14847

10. Interactive TUI Mode (pinspect tui)

Launches full-screen interactive dashboard:

pinspect tui

Interactive Keybindings:

• ↑ / ↓ / k / j: Navigate process list
• PgUp / PgDn / Home / End: Fast scroll
• Enter: Open process detail pane (tabs: Overview, Files, Network, Security, Env)
• /: Search / Filter processes in real time
• s: Cycle sort columns (CPU, MEM, PID, USER, NAME)
• r: Refresh process list
• q / ESC: Back / Quit

📊 SIEM / EDR Output Formats

Every subcommand supports structured serialization:

# Structured JSON for SIEM / EDR pipelines
pinspect ps --json
pinspect show 1234 --json
pinspect network --json
pinspect security 1234 --json

# CSV for data analysis & spreadsheets
pinspect ps --csv
pinspect files 1234 --csv
