prismlauncher - a launcher and instance manager for Minecraft.
prismlauncher [OPTIONS...]
Prism Launcher is a custom launcher for Minecraft that allows you to easily manage multiple installations of Minecraft at once. It also allows you to easily install and remove mods by simply dragging and dropping. Here are the current features of Prism Launcher.
-d, --dir=DIRECTORY Use DIRECTORY as the Prism Launcher root.
-l, --launch=INSTANCE_ID Launch the instance specified by INSTANCE_ID.
--show=INSTANCE_ID Show the configuration window of the instance specified by INSTANCE_ID.
--alive Write a small 'live.check' file after Prism Launcher starts.
-h, --help Display help text and exit.
-v, --version Display program version and exit.
-a, --profile=PROFILE Use the account specified by PROFILE (only valid in combination with --launch).
The behavior of the launcher can be customized by the following environment variables, besides other common Qt variables:
QT_LOGGING_RULES Specifies which logging categories are shown in the logs. One can enable/disable multiple categories by separating them with a semicolon (;).
The specific syntax, and alternatives to this setting, can be found at
https://doc.qt.io/qt-6/qloggingcategory.html#configuring-categories.QT_MESSAGE_PATTERN Specifies the format in which the console output will be shown.
