OCI Bastion SSH Connection Script Documentation

Overview

The oci-bastion-ssh-connect.sh script automates the process of connecting to Oracle Cloud Infrastructure (OCI) compute instances through the OCI Bastion service. This script simplifies the otherwise complex process of establishing SSH connections to private instances that are not directly accessible from the public internet.

Prerequisites

1. OCI CLI: Must be installed and configured on your system.
2. SSH Keys: A valid SSH key pair (public and private keys).

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;
