Cookbook of Raspberry Pi Commands

I am going to try to summarize most of my other pages for controlling setting up the raspberry Pi. We will see how it goes.

This is an article started by Russ Hensel, see "http://www.opencircuits.com/index.php?title=Russ_hensel#About My Articles" About My Articles for a bit of info. The page is only partly finished.Link title

Basic Config

Also stuff in GUI

sudo raspi-config  

Update

Commands like: not sure about the kernel one

sudo apt-get update  
sudo apt-get upgrade
sudo apt-get install raspberrypi-kernel
sudo apt-get dist-upgrade

Change Password

• as shipped id is pi password is raspberry. default user is pi , and the password is raspberry
• Change your password. When logged in as the pi user, you can change your password with the passwd command. Enter passwd on the command line and press Enter . You'll be prompted to enter your current password to authenticate, and then asked for a new password.

I believe you can do this through the preferences in the GUI now

passwd

WiFi

Edit this:

     sudo leafpad /etc/wpa_supplicant/wpa_supplicant.conf

Find contents like:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
	ssid="upstairs"
	key_mgmt=NONE
}

network={
	ssid="belkin.d3c"
	psk="secret"
	key_mgmt=WPA-PSK
}

another file

     sudo leafpad  /etc/network/interfaces

Find contents like:

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

get your ip address

     ifconfig
