What Pi Model & OS version is installed

Question

Users often seem confused about what Pi model they have and what OS version is installed or how to find details.

Where is this located?

Answer 1

The following script is one I use including the following commands to collect relevant details. (It is called aboutpi)

}

if [ -e /etc/rpi-issue ]; then
 print_head "- Original Installation"
 cat /etc/rpi-issue | grep reference

}

checkactive 'NetworkManager'

# Get SSID of connected WiFi (WRONG if AP!)
if [ -e /sys/class/net/wlan0 ]; then
    if [ $(systemctl is-active 'NetworkManager') = 'active' ]; then
        nmcli connection show |  awk '/wlan0/ {print $1}'
    else
        wpa_cli -i wlan0 status | grep -w ssid | awk -F'[=]' '{print $2}'
    fi
fi

sudo fdisk -l /dev/mmcblk0 | grep "Disk identifier"

CPUID=$(awk '/Serial/ {print $3}' /proc/cpuinfo | cut -c 9-)
# CPUID=$(vcgencmd otp_dump | grep 28: | cut -c4-)
echo "Serial: " $CPUID
if [ -e /opt/vc/bin/vcgencmd -o /usr/bin/vcgencmd ]; then
#   VERS=$(vcgencmd version  | grep ":")
    VERS=$(sudo vcgencmd version  | grep ":")
    print_head "- Firmware"
    echo $VERS

print_head "- Created"
sudo tune2fs -l $(mount -v | awk '/ on \/ / {print $1}') | grep created

Answer 2

A "quick and dirty" answer to the question follows. All can be entered from the command line interface:

1. cat /etc/os-release # provides NAMES, VERSIONS & some URLs for support

2. lsb_release -a # distribution-specific information; ref man lsb_release

3. hostnamectl # brief & useful incl hostname, OS ver, kernel ver; ref man hostnamectl

And as if you needed more, this command provides a terse summary with several options to get a specific item - which is useful in scripts to check version dependencies, etc. See man uname for details, and for example, the kernel version can be had as follows:

4. uname -r
