Shutdown Script for Retropie Use pin number 5 & 14 for “Shutdown” 1. Update RetroPie: • sudo apt-get update 2. Upgrade RetroPie • sudo apt-get upgrade 3. Install Python • sudo apt-get install python-dev • sudo apt-get install python3-dev • sudo apt-get install gcc • sudo apt-get install python-pip 4. Next you need to get RPi.GPIO: • wget https://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.5.11.tar.gz 5. Extract the packages: • sudo tar -zxvf RPi.GPIO-0.5.11.tar.gz 6. Move into the newly created directory: • cd RPi.GPIO-0.5.11 • 7. Install the module by doing: • sudo python setup.py install • sudo python3 setup.py install 8. Creating a directory to hold your scripts: • mkdir /home/pi/scripts 9. Call our script shutdown.py (it is written in python). Create and edit the script by doing: • sudo nano /home/pi/scripts/shutdown.py The content of the script: Paste it in the blank area #!/usr/bin/python import RPi.GPIO as GPIO import time import subprocess # we will use the pin numbering to match the pins on the Pi, instead of the # GPIO pin outs (makes it easier to keep track of things) GPIO.setmode(GPIO.BOARD) # use the same pin that is used for the reset button (one button to rule them all!) GPIO.setup(5, GPIO.IN, pull_up_down = GPIO.PUD_UP) oldButtonState1 = True while True: #grab the current button state buttonState1 = GPIO.input(5) # check to see if button has been pushed if buttonState1 != oldButtonState1 and buttonState1 == False: subprocess.call("shutdown -h now", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) oldButtonState1 = buttonState1 time.sleep(.1) Press CRTL X Then Y and Enter 10. Restart the pi • sudo reboot 11. Configure our script to run at startup, • sudo nano /etc/rc.local Add the following to the file • sudo python /home/pi/scripts/shutdown.py & Press CRTL X Then Y and Enter .

More to do Introduction For a beginner to the world of raspberry pi, there are a number of projects that can become the start of something big. In this article, I discuss such a simple project which is adding a button that can be used to shutdown the raspberry pi using a bit of software tinkering. I wrote a similar article in 2013 at my blog “embeddedcode.wordpress.com” and its got its share of attention since a lot of people starting out with a single board computer, kept looking for a power button. Additionally, those who wanted a headless system, needed a way to shutdown the computer without the mess of connecting to it over the network or attaching a monitor and keyboard to it. In this article, I revisit the tutorial on how to add a shutdown button while trying to explain the workings and perhaps beginners will find it an amusing to add find more things to do with this little recipe. What do you need? Here is a basic bill of materials required for this exercise.

Shutdown policies with power capping for large scale computing systems Anne Benoit1, Laurent Lef`evre1, Anne-C´ecileOrgerie2, and Issam Ra¨ıs1 1 Univ. Lyon, Inria, CNRS, ENS de Lyon, Univ. Claude-Bernard Lyon 1, LIP 2 CNRS, IRISA, Rennes, France Abstract Large scale distributed systems are expected to consume huge amounts of energy. To solve this issue, shutdown policies constitute an appealing approach able to dynamically adapt the resource set to the actual workload. However, multiple constraints have to be taken into account for such policies to be applied on real infrastructures, in partic- ular the time and energy cost of shutting down and waking up nodes, and power capping to avoid disruption of the system.

Freebsd Command Reference
FreeBSD command reference Command structure Each line you type at the Unix shell consists of a command optionally followed by some arguments , e.g. ls -l /etc/passwd | | | cmd arg1 arg2 Almost all commands are just programs in the filesystem, e.g. "ls" is actually /bin/ls. A few are built- in to the shell. All commands and filenames are case-sensitive. Unless told otherwise, the command will run in the "foreground" - that is, you won't be returned to the shell prompt until it has finished. You can press Ctrl + C to terminate it. Colour code command [args...] Command which shows information command [args...] Command which modifies your current session or system settings, but changes will be lost when you exit your shell or reboot command [args...] Command which permanently affects the state of your system Getting out of trouble ^C (Ctrl-C) Terminate the current command ^U (Ctrl-U) Clear to start of line reset Reset terminal settings.

Traceroute Mac Traceroute Mac
2] Chapter 2 Catalyst 3560 Switch Cisco IOS Commands traceroute mac traceroute mac Use the traceroute mac privileged EXEC command to display the Layer 2 path taken by the packets from the specified source MAC address to the specified destination MAC address. traceroute mac [interface interface-id] {source-mac-address} [interface interface-id] {destination-mac-address} [vlan vlan-id] [detail] Syntax Description interface interface-id (Optional) Specify an interface on the source or destination switch. source-mac-address Specify the MAC address of the source switch in hexadecimal format. destination-mac-address Specify the MAC address of the destination switch in hexadecimal format. vlan vlan-id (Optional) Specify the VLAN on which to trace the Layer 2 path that the packets take from the source switch to the destination switch. Valid VLAN IDs are from 1 to 4094. detail (Optional) Specify that detailed information appears. Defaults There is no default. Command Modes Privileged EXEC Command History Release Modification 12.1(19)EA1 This command was first introduced. Usage Guidelines For Layer 2 traceroute to function properly, Cisco Discovery Protocol (CDP) must be enabled on all the switches in the network. Do not disable CDP. When the switch detects a device in the Layer 2 path that does not support Layer 2 traceroute, the switch continues to send Layer 2 trace queries and lets them time out. The maximum number of hops identified in the path is ten. Layer 2 traceroute supports only unicast traffic. If you specify a multicast source or destination MAC address, the physical path is not identified, and an error message appears.

Shell Commands
Operating Systems Lab Islamic University – Gaza Engineering Faculty Department of Computer Engineering Fall 2012 ECOM 4010: Operating Systems Lab Eng: Ahmed M. Ayash Lab # 5 Shell Commands October 6, 2012 Linux Shell (Terminal): Shell Definition: is a special Linux component that acts as interface between user and kernel. Shell accepts user commands in English and passes them to the kernel to execute. Shell is a command language interpreter that executes commands read from keyboard or from a file. Shell is not part of the kernel; it uses it to execute programs. Shell Types: 1- BASH (Bourne-Again SHell): it is a freeware shell and most common shell in Linux. 2- CSH (C Shell): The C shell's syntax and usage are very similar to the C programming language. 3- KSH. 4- TCSH. 5- ZSH 6- BSH Tip: To find all available shells in your system type following command: $ cat /etc/shells By default, the BASH shell has a dollar sign ($) prompt, but Linux has several other types of shells, each with its own prompt. A shell prompt, such as the one shown here, marks the beginning of the command line: $ Structuring Commands - Commands have the following syntax: command options arguments 1 Some Shell Commands Command Syntax Function man $ man {command name} Get help about commands. info $ info {command name} Get help about commands. --help $ {command name} --help Get help about commands. whatis $ whatis {command name} Get help about commands. cat $ cat {file name} Display text file. date $ date Display current date and time $ date --date= '2012-10-10' Set the date to 2010-10-10(y,m,d).
