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

fixed ip address

need to make sure this still works on 2018 os

• [1]

sudo leafpad /etc/dhcpcd.conf

Scroll all the way to the bottom of the file and add one, or both of the following snippets. Depending on whether you want to set a static IP address for a wired connection or a wireless connection eth0 = wired, wlan0 = wireless. You’ll need to edit the numbers in the snippet so they match your network configuration.

• interface = This defines which network interface you are setting the configuration for.
• static ip_address = This is the IP address that you want to set your device to. (Make sure you leave the /24 at the end)
• static routers = This is the IP address of your gateway (probably the IP address or your router)
• static domain_name_servers = This is the IP address of your DNS (probably the IP address of your router). You can add multiple IP addresses here separated with a single space.

• my next Rasberry Pi 178/179

interface eth0

static ip_address=192.168.0.176/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

interface wlan0

static ip_address=192.168.0.200/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

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

Linux Reminders

ls      # list files
sudo chmod +x /home/pi/pi3.sh    # make executable 

mkdir make directory
rmdir – Remove Directories

[edit] Files
rm – Remove Files

mv – Move Files
~ home directory
./ current directory
../ parent directory
ls list files, but may miss hidden ones then ???
cd
chmod +x filename +x make executable
ps -e what is running ( -e all users?? without just current )
top info on running processes in a nano like window exit with ctrl c
kill end a process using pid from above

cp copy files
code
