In order to be able to use these scripts a few external dependencies have to be met. Most of them should already be installed on any Linux distribution.

Order of the list is from what you probably have to install yourself to what probably is installed anyway:

start-stop-daemon

as the name suggests it is used to start the game as a daemon. Available on Debian based distributions. Users of other distributions can compile it from source

​XMLStarlet

used to manipulate serverconfig.xml

Wine

run 7dtd Windows build on Linux. Required as long as there is no native Linux build of 7dtd

mono-runtime

required by 7dtd as Unity is based on Mono

Xvfb

required for Wine as it requires a screen

---

Everything below should be installed already:

wget

downloads SteamCMD

rsync

create incremental backups of game data

pkill

stops the server log monitoring

netstat

showing the open ports

Bash

the whole thing heavily relies on features of Bash

Init system

for automatic start of 7dtd on server boot (Script designed for SysVInit, it should also work with systemd)

cut, tr, tail, stdbuf

stream manipulation

grep, sed, dd, date, mkdir, touch, nc

tools really every Linux distro should ship anyway ;)
