Push LÖVR files to org.lovr.app on a Quest, restart the app, and start logging. I have this in my ~/.zshrc as "load". (public domain CC0)

loadquest.zsh

# === loadquest ===
# push lovr files to org.lovr.app on a Quest, restart the app, and start logging.
#
# usage:
# navigate to a folder with a main.lua, and do
#   loadquest
# or navigate to a folder with your files, and do
#   loadquest gorilla.lua
# in the latter case, gorilla.lua will be renamed to main.lua on the Quest.

loadquest() {
    # if we provide an argument
    if [ $# -ne 0 ] 
    then
        # then that's the filename we want to rename to main.lua. still push the whole folder
        adb push --sync . /sdcard/Android/data/org.lovr.app/files
        adb shell mv /sdcard/Android/data/org.lovr.app/files/$1 /sdcard/Android/data/org.lovr.app/files/main.lua
    else
        # else, still push the whole folder
        adb push --sync . /sdcard/Android/data/org.lovr.app/files
    fi
    adb shell am force-stop org.lovr.app
    adb shell am start org.lovr.app/org.lovr.app.Activity
    adb logcat -s LOVR
}
