TeamSpeak 3 Server Installer and Updater

A lightweight script to install or update a TeamSpeak 3 server on Linux or FreeBSD. Should also work on macOS (currently untested).

Dependencies

jq 1.4 or newer (https://stedolan.github.io/jq/download/)
curl
shasum, sha256, or sha256sum
tar
bzip2

All other dependencies (basename, cd, command, cut, dirname, echo, grep, mktemp, printf, read, sed, test, touch, uname, wc, and an sh-compatible shell) are installed by default on most systems.

How to use

Install a new TeamSpeak 3 server

Place the script where you want to install the TS server, make it executable with chmod +x ts3updater.sh and run it with ./ts3updater.sh. After the installation, the script moves itself into the installation folder. Run it from there whenever you want to update the server.

Update an existing TeamSpeak 3 server installation

Place the script in the directory of your existing TS installation. This means, the script has to be in the same directory as for example the file ts3server_startscript.sh. Make it executable with chmod +x ts3updater.sh and run it with ./ts3updater.sh.

If you use TSDNS, make sure the service is stopped before you execute this script.

Update the server automatically

As the server is only updated if a new version is available, you can also use the script to automate updates. Simply create a cronjob which executes the script for instance hourly or daily. A crontab entry to run ts3updater daily at 13:28 could look like this: 28 13 * * * /home/ts/teamspeak3-server_linux_amd64/ts3updater.sh. Append >/dev/null 2>&1 if you don't want to get a mail each time the script is run.

You must accept the server license agreement before you create the cronjob. To do so, go to the directory of your TS installation, read the file LICENSE and create a file called .ts3server_license_accepted.

Commandline parameters

All parameters are passed to ts3server_startscript.sh when the server is started. If you don't want to start the server after installing or updating, use the parameter --dont-start.

What this script is doing

Determine the OS and CPU architecture
Check if there is an existing installation and determine its version
Check for newer versions
If there is a newer version:
