I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

C# For Python Programmers

Syntax and core concepts

Basic Syntax

Single-line comments are started with //. Multi-line comments are started with /* and ended with */.
C# uses braces ({ and }) instead of indentation to organize code into blocks. If a block is a single line, the braces can be omitted. For example,

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
