Port Check Skill
Quickly verify if services are up and responding on specific ports.
Usage
# 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) - ⚠️
