During SDKMAN installation, the phrase '$' is not an internal or external command, an executable program, or a batch file

To install sdkman from cmd $ I typed curl -s "https://get.sdkman.io" | bash "'$' is an internal or external command, an executable program, or This is not a batch file."

Even if you add a path from the environment variable to the directory just before $, the error continues to occur I'd like to ask you what to do
