The documentation online can be confusing, especially with config paths from old files floating around.

1. Download an image file for RetroPi (Ideally 2.5+)
2. Unzip the image file, plug in your SD card (likely /dev/sdb)
3. dd if=retropi.img of=/dev/sdb (this will erase your entire SD card)
4. Optional: increase the size of the new partition with gparted

System Setup
1. Add your ROMs to ~/RetroPi/roms/snes (which will cause your EmulationStation to now show the system in the menu). Be sure to unzip them.
2. (Not needed in RetroPie 2.5) Update your controller config, either by running ~/retropi_setup/retropi_setup.sh, or copying a known config to /opt/retropie/emulators/RetroArch/USB,2-axis8-buttongamepad.cfg

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
