List all user-installed packages on OpenWrt / LEDE

list-user-installed-packages.sh

#!/bin/sh

FLASH_TIME=$(opkg info busybox | grep '^Installed-Time: ')

for i in $(opkg list-installed | cut -d' ' -f1)
do
    if [ "$(opkg info $i | grep '^Installed-Time: ')" != "$FLASH_TIME" ]
    then
        echo $i
    fi
done

And yet another variant. This one produces a more accurate/minimal list, as it also skips all dependents of other packages. It's based on bash, as it uses associative arrays.

Thanks @guymarc! Your script is the only one that worked for me. The other scripts here just list every single package installed. Maybe it is that way because I also used the Image Builder.

as someone suggested on https://www.sindastra.de/p/1213/list-user-installed-packages-in-openwrt

You can update busybox via opkg update, so it’s install time can be wrong as reference.
As a result you will have wrong list.
Only one thing you cannot install via opkg is kernel – because you update it over flashing new firmware.
So the kernel’s install time should be used as flash time.
FLASH_TIME=$(opkg info kernel | grep ‘^Installed-Time: ‘)
