rcon_announce script: Periodically display a set of three messages after five minutes + two other messages, after 30 seconds, counted from the five minutes. rcon_commands script: Execute commands requested by a player; currently, the commands are: !date (date Unix command), !info (uname⠀-a Unix command), !script (script information; credits), !warp (manage warps) and !guild (manage guilds). rcon_commands also includes an authentication feature, based on the username + IP address of the player, both of which are saved to a file (auth). If either the username or IP address already exists in the database (auth file), the script will check whether username + IP address, as a single string, coincides or not in the database; if it does not, the player is kicked from server.
Although I only wrote two scripts, more is to come; thus, a collection.
Since I made them on GNU/Linux, it is unlikely that Unix or other Unix-like operating systems (including macOS) be able to run them, because GNU programs tend to be and act different than these found in Unix and other Unix-like operating systems. However, *BSD and illumos users may already have or can install GNU programs, so they just need to adapt their environment.
Windows users may use Cygwin to run the scripts. NOTE: Even though GNU programs are different than these found in Unix and other Unix-like operating systems, I'm writing the scripts with POSIX in mind.
