BASH Script for Arma 3 MODs updating/downloading for Linux Servers

This script is a full interactive. The complete automatic start is planing but not implemented yet.

Script's abilities:

  • Check an all installed MODs for updates in a Steam Workshop
  • Update one selected MOD by its name
  • Update all MODs, which are updated in a Steam Workshop in a batch mode.
  • Download MOD by Steam AppID
  • Fix missed Steam AppID in 'meta.cpp' file during updating/downloading process.
    • REM: To make fixing possible during an Updating process it need to be a manually edited once at a first time before update of the selected MOD will started. All further updates will fix automatically it again and again.
  • Transform the files and directories names from UPPER to LOWER case

Dependencies

  • curl
  • wget
  • steamcmd
  • rename

Intstallation:

  1. Clone or download this script to the /home directory of a user which is running an Arma 3 server.
  2. Set up the permissions to execute it for user.
  3. Update paths to installed Arma 3 Linux Server mods, to the Workshop directry, where Steam downlading the modes and where the steamcmd.sh is located.
  4. OPTIONAL: You can create an external file auht.sh in a folder a step above of a a3upddownmod.sh is located and to store your Steam credentials there. The password should be encrypted with a base64 encryption.

To create your own auth.sh file make the followed (Enter your own Steam credentials before executing!):

echo '#!/bin/bash' > auth.sh && echo "" >> auth.sh
echo "STEAM_LOGIN=\"YOUR_STEAM_LOGIN\"" >> auth.sh
echo "STEAM_PASS=\"$(echo "YOUR_STEAM_PASSWORD" | base64)\"" >> auth.sh

Usage:

CLI

Run ./a3upddownmods.sh -h for CLI usage overview (Check/Update available only for now).

If you want to use this script to check or to update the mods automatically and want you to be notified about it - do the next:

cp notify_update_status.sh.example notify_update_status.sh && nano notify_update_status.sh

Update url= variable to your Discord WEB-hook URL.

Add the script with needed parameters to you CRON (or to systemd timer job). For example 0 3 * * * /home/steam/a3upddownmods/a3upddownmods.sh -cn to check for updates automatically.

I recommend to automatically check for updates ONLY and to do not use an automatic update as in this case you'll need to update mod's keys in server keys folder and to restart server manually anyway.

Interactive

Run the script and follow an instructions for interactive usage.

Plans

  1. Run script with a CLI options to make all jobs automatically (partially done)
