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. [[start-stop-daemon|Users of other distributions can compile it from source]]
 [http://xmlstar.sourceforge.net/ 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 ;)
