        This command is using SASS to watch changes in a specified file and compile it into CSS whenever there are modifications. Let's break down the different components:
- 
sassis the command-line tool for processing SASS/SCSS files.
- 
--watchis a flag that instructs Sass to continuously monitor the specified file for changes. Whenever the file is modified, Sass will automatically compile it into CSS.
- 
${select}is a placeholder that represents the path or filename of the SASS/SCSS file that you want to watch and compile.
- 
${outputfile-css}is another placeholder referring to the desired name of the output CSS file that Sass will generate.
By replacing ${select} with the path or filename of your SASS/SCSS file and ${outputfile-css} with the name you want for the output CSS file, you can use this command to watch for changes in your SASS/SCSS file and compile it into CSS on-the-fly.
