Merge Queue CLI Reference

The Trunk CLI allows you to insert and remove PRs into the Merge Queue. You can also pause and resume the queue from the CLI.

Installation

curl -LO https://trunk.io/releases/trunk
chmod +x trunk

Prerequisites

Before using the CLI:

  • Authenticate: Run trunk login

  • Git repository: Execute commands from your repository root

Usage

trunk merge [flags] <pr-number>
trunk merge [subcommand]

Submit a PR to the Queue

trunk merge <pr-number> [flags]

Arguments

<pr-number> - Pull request number to submit. Can be specified with or without # prefix (e.g., 1234 or #1234)

Flags

-p, --priority <0-255> - Priority determines the order PRs are tested and merged. When a PR is submitted with a priority, it will begin testing before any lower priority PR that isn't currently being tested. Levels:

  • 0 (Urgent) Interrupts currently testing PRs to begin testing immediately. Use sparingly as restarting tests is costly. This is the only priority that interrupts running tests

  • 10 (High) Tests before default priority PRs

  • 100 (Default) Used when no priority is specified

  • 200 (Low) Tests after default priority PRs

  • 255 ( Lowest) Lowest possible priority

If multiple PRs have the same priority, they are processed in the order they were submitted. See Priority Levels.

Examples

trunk merge 1234

Cancel a PR

Remove a pull request from the merge queue. Use cases:

  • Cancel before making additional changes to the PR

  • Cancel to resubmit with different priority

trunk merge cancel <pr-number>

Pause Queue [admin only]

Pause the merge queue, changing its state from Running to Paused. The ordering of PRs in the queue is preserved while paused.

trunk merge pause

When to use:

  • CI failure recovery - Stop merges and testing until infrastructure issues are resolved

  • Test infrastructure outages - Pause until systems are back online

  • Emergency situations - Prevent any merges during incident response

  • Scheduled maintenance - Block merges during maintenance window

Resume Queue [admin only]

Resume merge queue processing, changing its state from Paused back to Running. The queue will begin testing waiting PRs in priority order.

trunk merge resume
