Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Clearing Nginx's HTTP Cache

I recently implemented Nginx HTTP content caching on our WordPress web servers to improve page load speeds and eliminate redundant, unneeded server-side page rendering. Caching the pages was relatively straightforward, but clearing the cache required a custom workaround.

Nginx comes in two versions: free and “Nginx Plus” at $2,500/year. The free version of Nginx does not offer the needed cache-clearing features of Nginx Plus, and I wasn’t comfortable paying $20,000 for 8 instances without trying to build my own solution.

Our Nginx servers run as an HTTP proxy for multiple PHP/MySQL-backed WordPress sites. The goal was to cache the dynamic PHP HTML responses in Nginx and serve the HTML pages from Nginx to avoid redundant, CPU-intensive PHP renders.

Site Cache Configuration

The example below shows how PHP response caching is configured for a site (other nginx configuration details are excluded for brevity). A cache named cachedemo-prod is defined to store cached HTML f

I've bought this new controller from 8BitDo and wished to use on linux, to my sadness the controller didn't work out of the box, neither by cable, the 2.4G dongle or bluetooth.

So I've tried a number of solutions and this one from u/GodOfEmus over in the 8bitdo community was the one to work for me:
