qzx killProcess

What it does

Terminates one explicitly identified process and verifies that it exited

Command maturity: Alpha

Available for real use and feedback while its interface and behavior can still evolve. This is the current development-checkout assessment. Every future immutable release tag preserves the exact assessment shipped by that version. Available in PyPI 0.2.2.0.8. This page documents the 0.2.2.0.8 alpha development checkout.

Behavior and built-in protections

Live mode applies the changes you request

Direct execution for this operation

Works without invoking native programs

Works without network access

Uses your current permissions; results can vary

For an operation without a restorable path, QZX asks for explicit --dangerously-bypass-approvals-and-sandbox or --yolo acknowledgement.

This safety classification was reviewed by OpenAI GPT-5.6 Pro against implementation digest sha256:2c400c779ac1dd25cd21676c0e2394351c2ca602099157d049cfcf4521b0f4b3 on 2026-08-25.

Exact syntax

qzx killProcess <pid> [force] [expected_create_time] [wait_seconds] --json

Parameters

Swipe or use the horizontal scrollbar to see every column.

NameTypeRequiredDefaultDescription
pidintYesNot declaredPositive process ID to terminate
forceboolNofalseUse an immediate forced kill instead of graceful termination
expected_create_timefloatNoNot declaredOptional process creation timestamp observed immediately before termination; prevents PID-reuse mistakes
wait_secondsfloatNo5Seconds to wait for verified process exit (0.1 to 60)

Input examples

qzx killProcess 1234 --expected-create-time 1750000000.25 --yolo

Terminate exactly the previously inspected process and verify that it exits

qzx killProcess 1234 --force --dangerously-bypass-approvals-and-sandbox

Force-kill PID 1234 when graceful termination is not appropriate

For the complete structured payload, add --json: qzx killProcess <pid> [force] [expected_create_time] [wait_seconds] --json

Representative output example

This illustrative JSON is derived from the current implementation-backed result contract. It shows what the command can return without claiming a recorded execution; values vary with inputs, host, permissions, and optional tools.

Example command: qzx killProcess 1234 --expected-create-time 1750000000.25 --yolo --json

Errors and limits

The public contract requires success=false and a descriptive message on failure. This catalog does not yet declare a command-specific error taxonomy; inspect the result and do not invent error codes.

QZX is alpha software. Optional dependencies, permissions, and host capabilities can change the result.

Evidence workflow: requires a controlled privileged environment.
