prqlc:tldr:36c85

This command takes the value stored in the variable ${select} and passes it as input to the prqlc compile command.

Here's how it works:

• The echo command is used to output the value of ${select}.
• The value is then piped (|) to the prqlc compile command, which is executed.
• The prqlc compile command is likely a command that compiles or processes some SQL-like code or queries, using the input that is passed to it via the pipe.

Overall, this command is used to provide the value of ${select} as input to prqlc compile command, allowing the code or queries stored in ${select} to be compiled or processed.
