moveAddons.sh

#!/bin/bash

# Folder where the incorrect downloaded mutators are
CACHE_FOLDER=~/.killingfloor/Cache
# Folder where they should be after renamed
STEAM_SYSTEM_FOLDER=~/.steam/steamapps/common/KillingFloor/System


cd $CACHE_FOLDER

while read p; do
  # For each non-empty entry of cache.ini
  if [ -n "$p" ]
    then
        IFS='=' read -r -a array <<< "$p"
        echo "${array[0]}.uxx"
        echo "${array[1]}"
        # Move the file to the steam folder with the correct name
        mv $CACHE_FOLDER/"${array[0]}.uxx" $STEAM_SYSTEM_FOLDER/${array[1]}
  fi
done < cache.ini

# Erase the previous values from the cache.ini file
echo "[Cache]" > cache.ini

This was tested on Ubuntu 18.04 and after running it the perks are saved. just make sure to run it every time you download an addon.
