The command "kool completion ${select}" is using the kool command line tool to generate completion scripts for a specified shell (represented by the ${select} variable).
The "kool completion" command is a feature provided by the kool tool that generates shell completion scripts, which allow you to use auto-completion for kool commands and options when typing on the command line.
The "${select}" portion of the command is a placeholder for the name of the shell you want to generate the completion script for. It should be replaced with the actual name of the shell, such as "bash" or "zsh". For example, if you want to generate a completion script for the bash shell, you would use the command: "kool completion bash".
By running this command, kool will generate the appropriate completion script for the specified shell, which you can then use to enable auto-completion for kool commands and options in your shell.
