WP-CLI and Operations

Skill for the safe and effective use of WP-CLI in day-to-day WordPress operations. Covers migrations, plugin/theme management, cron, cache, database, and automation patterns.

When to use

Apply this skill when the task involves:

• wp search-replace

  (URL change, domain migration, protocol switch)
• Database export/import (

  wp db *

  )
• Plugin and theme management (install, activate, update)
• Cron: list events, manual execution, debugging
• Cache and rewrite flush
• Automation scripts and

  wp-cli.yml

Prerequisites

Before starting, verify:

• Environment: dev, staging, or production — and whether it is safe to run commands
• Targeting:

  --path=<wordpress-root>

  to point to the correct installation
• Constraints: acceptable downtime, DB write permissions, maintenance window

Procedure

0) Guardrails — confirm environment and blast radius

WP-CLI commands can be destructive. Before any write operation:

1. Confirm the environment (dev/staging/prod)
2. Verify targeting — does the path point to the right site?
3. Back up before risky operations

# Verify where you are.
wp core version
wp option get siteurl
wp option get blogname

# Verify you are targeting the right site.
wp eval "echo get_home_url();"

Golden rule: if you are unsure about the environment, do not run write commands.

1) URL migration / search-replace

The safe sequence for changing URLs in the database:

# 1. Back up BEFORE anything.
wp db export backup-pre-migration.sql

# 2. Dry-run — see what would change without touching the DB.
wp search-replace 'https://vecchio-dominio.it' 'https://nuovo-dominio.it' --dry-run --report-changed-only

# 3. If the dry-run is ok, execute.
wp search-replace 'https://vecchio-dominio.it' 'https://nuovo-dominio.it' --report-changed-only

# 4. Flush cache and rewrite after migration.
wp cache flush
wp rewrite flush

Beware of serialized data:

wp search-replace

Useful flags:

--dry-run

--report-changed-only

--all-tables

--precise

--skip-columns=<col>

2) Plugin and theme management

# List plugins with status.
wp plugin list --format=table

# Install and activate.
wp plugin install advanced-custom-fields --activate

# Update all (dev/staging).
wp plugin update --all
wp theme update --all

# Deactivate a plugin.
wp plugin deactivate plugin-problematico

# Check status.
wp plugin status

In production: update one plugin at a time, verify after each one.

3) Database — export, import, query

# Full export (backup).
wp db export backup-$(date +%Y%m%d-%H%M%S).sql

# Export with gzip (smaller files).
wp db export - | gzip > backup.sql.gz

# Import.
wp db import backup.sql

# Direct queries (read-only for debugging).
wp db query "SELECT COUNT(*) FROM $(wp db prefix)posts WHERE post_type = 'bando' AND post_status = 'publish'"

# Database size.
wp db size --tables --format=table

Never run

wp db reset

4) Cron — diagnosis and debugging

# List all scheduled cron events.
wp cron event list --format=table

# Run a single event (for debugging).
wp cron event run mio_plugin_cron_event

# Count "due now" events (if too many, there is a problem).
wp cron event list --format=count --fields=hook --status=due

# Test: is the cron system working?
wp cron test

• If there are too many "due now" events: probably

  DISABLE_WP_CRON

  is true but the system crontab is not configured
• For heavy tasks: system crontab is better than

  wp-cron.php

  via HTTP

5) Cache and rewrite

# Flush object cache.
wp cache flush

# Flush rewrite rules (after changing CPTs/taxonomies).
wp rewrite flush

# Regenerate rewrite rules and show them.
wp rewrite list --format=table

# Flush expired transients.
wp transient delete --expired

6) Automation — wp-cli.yml and scripts

Create a

wp-cli.yml

# wp-cli.yml
path: web/wp          # For Bedrock
url: https://mio-sito.ddev.site
color: true

Automation script with logging and stop-on-error:

#!/bin/bash
set -euo pipefail

LOG_FILE="ops-$(date +%Y%m%d-%H%M%S).log"

log() {
    echo "[$(date +%H:%M:%S)] $*" | tee -a "$LOG_FILE"
}

log "Starting operations..."

# Backup.
log "Backing up database..."
wp db export "backup-$(date +%Y%m%d).sql"

# Update plugins.
log "Updating plugins..."
wp plugin update --all 2>&1 | tee -a "$LOG_FILE"

# Flush cache.
log "Flushing cache..."
wp cache flush
wp rewrite flush

log "Operations completed."

Quick reference commands

# Quick site info.
wp core version && wp option get siteurl && wp plugin list --status=active --format=count

# Generate a test admin user (dev only).
wp user create admin-test admin@test.local --role=administrator --user_pass=test123

# Regenerate thumbnails.
wp media regenerate --yes

# Export content as WXR.
wp export --dir=.

# Verify core file integrity.
wp core verify-checksums

# Search for a string in the database.
wp db search "stringa-da-trovare" --format=table

Verification checklist

• Environment confirmed before write operations
• Backup performed before risky operations

• --dry-run

  executed before

  search-replace

• Site URL correct after migration (

  wp option get siteurl

  )
• Plugins/themes in the expected state
• Cron working (

  wp cron test

  )
• Cache flushed where necessary

Common errors and solutions

--precise

What NOT to do

• Do not run

  wp db reset

  or

  wp db drop

  without a verified backup
• Do not run

  wp search-replace

  without

  --dry-run

  first
• Do not update plugins in production without having tested in staging
• Do not assume

  --path

  is correct — always verify with

  wp option get siteurl

• Do not use

  wp-cron.php

  via HTTP for heavy tasks in production — use system crontab
• Do not run

  wp cache flush

  during traffic spikes without reason
