gaols / main.go

Companion code for the Linux terminals blog series

	// Companion code for the Linux terminals blog series: https://dev.to/napicella/linux-terminals-tty-pty-and-shell-192e
	// I have simplified the code to highlight the interesting bits for the purpose of the blog post:
	// - windows resizing is not addressed
	// - client does not catch signals (CTRL + C, etc.) to gracefully close the tcp connection
	//
	// Build: go build -o remote main.go
	// In one terminal run: ./remote -server
	// In another terminal run: ./remote
	//
	// Run on multiple machines:
