Tutorial show armbian-package versions in login motd

guidol · October 3, 2019

A while ago I did create a armbian-package-information for at the motd of the login:

Now the line for the kernel does show 2 versions because there are "Version:" and "Config -Version:"

root@npi-neo2-24(192.168.6.24):~# dpkg -s linux-image-$BRANCH-$LINUXFAMILY|grep Version
Version: 5.96
Config-Version: 5.96

root@npi-neo2-24(192.168.6.24):~# dpkg -s linux-image-$BRANCH-$LINUXFAMILY|grep Version|cut -f 2 -d ' '
5.96
5.96

So I had to find another way/command to get the information once
I did go back from "dpkg -s" to "dpkg -l" and greped there the version-info:

root@npi-neo2-24(192.168.6.24):~# dpkg -l | awk -v env_var="linux-image-$BRANCH-$LINUXFAMILY" '$2==env_var { print $3 }'
5.96

# end-part of /etc/update-motd.d/10-armbian-header
# NEW version
# ===============================================================================================================
ARMBIAN_bsp=$(more /etc/armbian-release|grep VERSION|cut -f 2 -d '=')
ARMBIAN_kernel=$(dpkg -l | awk -v env_var="linux-image-$BRANCH-$LINUXFAMILY" '$2==env_var { print $3 }')
ARMBIAN_uboot=$(dpkg -l | awk -v env_var="linux-u-boot-$BOARD-$BRANCH" '$2==env_var { print $3 }')
ARMBIAN_dtb=$(dpkg -l | awk -v env_var="linux-dtb-$BRANCH-$LINUXFAMILY" '$2==env_var { print $3 }')
ARMBIAN_firmware=$(dpkg -l | awk -v env_var="armbian-firmware" '$2==env_var { print $3 }')
ARMBIAN_config=$(dpkg -l | awk -v env_var="armbian-config" '$2==env_var { print $3 }')

printf 'package bsp-kernel[\e[0;91m%s\x1B[0m] u-boot[\e[0;91m%s\x1B[0m] dtb[\e[0;91m%s\x1B[0m] firmware[\e[0;91m%s\x1B[0m] config[\e[0;91m%s\x1B[0m]\n' "$ARMBIAN_kernel" "$ARMBIAN_uboot" "$ARMBIAN_dtb" "$ARMBIAN_firmware" "$ARMBIAN_config"
printf '\n'
# ===============================================================================================================

After successfully getting the kernel-version only once- I edited the other commands to the "dpkg -l" version - and the result is clear as before

Welcome to Debian Buster with Armbian Linux 5.3.3-sunxi64
package bsp-kernel[5.98.191003] u-boot[5.96] dtb[5.98.191003] firmware[5.96] config[5.96]

The only drawback is, when you use a dev-kernel/-dtb on a next-installation (using other kernel via armbian-config) then $BRANCH is next and your kernel is dev

root@npi-neo2-24(192.168.6.24):~# dpkg -l|grep image

# ARMBIAN_kernel=$(dpkg -l | awk -v env_var="linux-image-$BRANCH-$LINUXFAMILY" '$2==env_var { print $3 }')
ARMBIAN_kernel=$(dpkg -l | awk -v env_var="linux-image-dev-$LINUXFAMILY" '$2==env_var { print $3 }')

# ARMBIAN_dtb=$(dpkg -l | awk -v env_var="linux-dtb-$BRANCH-$LINUXFAMILY" '$2==env_var { print $3 }')
ARMBIAN_dtb=$(dpkg -l | awk -v env_var="linux-dtb-dev-$LINUXFAMILY" '$2==env_var { print $3 }')

PS: I also did try - before this - the package apt-show-versions (lists available package versions with distribution)

but this takes much too long to resolve and needs this additionally package
