Port Check Skill

Quickly verify if services are up and responding on specific ports.

Usage

bash
# Basic TCP check
bash scripts/port-check.sh localhost:8080 localhost:5432

# Multiple targets with HTTP status check
bash scripts/port-check.sh localhost:80 api.example.com:443 --http

# Custom timeout (default 3s)
bash scripts/port-check.sh 192.168.1.1:22 --timeout 5

Output

  • host:port — open (TCP connected)
  • host:port — open (HTTP 200) (with --http flag)
  • ⚠️ host:port — open but HTTP 500 (port open, bad HTTP status)
  • host:port — closed/timeout (no response)

Exit Codes

  • 0 — all targets up
  • 1 — one or more targets down
