Minecraft: Filter Matrix AC trial message with grep

sh

java -Dterminal.jline=false -Dterminal.ansi=true -jar Paper-*.jar nogui | grep --color=never --invert --extended-regexp '^.{0,3}\[[[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2} INFO\]: '"$(printf \\e)"'\[[0-9;]*m\[Matrix\] '"$(printf \\e)"'\[[0-9;]*m\(!\) You are currently using free\(trial\) version of Matrix!'"$(printf \\e)"'\[[0-9;]*m$'

-Dterminal.jline=false -Dterminal.ansi=true - Force colored output even though we are piping to grep.
.{0,3} - Output can start with 0-3 garbage characters (usually ansi escape codes). This check can be improved.
\[[[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2} INFO\]: - Message timestamp and type.
'"$(printf \\e)"'\[[0-9;]*m\[Matrix\] '"$(printf \\e)"'\[[0-9;]*m\(!\) You are currently using free\(trial\) version of Matrix!'"$(printf \\e)"'\[[0-9;]*m$' - Actual message. Each printf instance converts \ESC[123m codes.

• Are you on the latest version of Paper spigot?
• Is your paper jar named Paper-*.jar where * is anything?
• Are you using Linux? You need Linux for this (or a bash shell with gnu corelibs installed). If you don't know what Linux is, you probably aren't using it.
