Sometimes you may find yourself in a minimalistic environment where common tools like `curl` or `wget` are not available to check web content or service health. In such cases, you can use basic shell commands to achieve similar functionality.

The following example with be alternative to curl http://localhost:8080/health/ready or wget -qO- http://localhost:8080/health/ready using just bash built-in capabilities:

exec 3<>/dev/tcp/localhost/8080
echo -e "GET /health/ready HTTP/1.1\r\nHost: localhost\r\nConnection: close\r\n\r\n" >&3
cat <&3
exec 3>&-
