Raspberry Pi - Update Raspberry Pi Script

While searching, I found a great little post on cagewebdev.com for quickly running your Raspberry Pi through all of its updates. The original post is here.

My only modification is I created the script in the logon user's /home directory instead of putting in a separate Code directory due to to single use of my Pis currently. While it may be ultimately a bad practice to not properly put all scripts into a dedicated directory, it provides the current ease of access that I desire.

Here is the process:
Create the shell script:
nano updatepi.sh
Copy/Paste(click) or manually type the following into the Nano screen:
#!/bin/bash
date
echo UPDATING SYSTEM SOFTWARE – UPDATE
sudo apt-get update
echo UPDATING SYSTEM SOFTWARE – UPGRADE
sudo apt-get upgrade -y
echo UPDATING SYSTEM SOFTWARE – DISTRIBUTION
sudo apt-get dist-upgrade
echo REMOVING APPLICATION ORPHANS
sudo apt-get autoremove –y
echo UPDATING FIRMWARE
sudo rpi-update
 Once complete, Save (Ctrl+X, then Enter) and exit (Ctrl+X).

Now, we need to make the script executable:
sudo chmod +x updatepi.sh
 Lastly, lets run the script:
sudo ./updatepi.sh
Depending on what updates are needed, you may be prompted to enter Y or N to continue the process. If a firmware update is installed, you may also require a reboot to make the change.
To restart immediately, run:
sudo reboot

  1. Soon after this, the power to print with various other supplies obtained business much more excited. From an engineering standpoint, this was an enormous deal, offering all types of choices in elements manufacturing. At the tip of this adolescent interval in 3D printing history we started to see various collaborative co-creation best men's baseball hats companies seem. Nowadays, folks can exhibit their designs, share ideas, and freely swap data. With 3D printing, you also have to upload a digital file to the printer.

  2. The welcome bonus begins from 코인카지노 $45 so any deposit lower than this amount won't be eligible for the promo. You’re in a position to} get entry to the on line casino from any state throughout the US. Given that Big Spin Casino is positioned offshore, it means its license isn't within the US and therefore does not adhere to strict rules from the nation.
