ruby - What are the options for RUBYOPT env?

Question

All I could find out is -W:no-deprecated & -W:no-experimental flags.

I have tried to understand through RUBYOPT's spec but got lost. Are there any other options available for the RUBYOPT env?

检查 Ruby 联机帮助页（运行man ruby）。

RUBYOPT    Additional Ruby options.

  e.g. RUBYOPT="-w -Ke"

  Note that RUBYOPT can contain only -d, -E, -I, -K, -r, -T, -U, -v, -w, -W, --debug, --disable-FEATURE and --enable-FEATURE.
