The command shown in Listing 

2-8

 watches the .scss files for any changes. Whenever you modify and 

save the .scss file, Sass will compile and generate the output .css file. Thus the code given in Listing 

2-8

 can 

be broken down in following manner:

•  sass (main component that indicates that this is a Sass command)

•  --watch (action this command is supposed to perform)

•  style.scss:style.css (input and output file separated by colon)

You can find out more about the command options by typing the command shown in Listing 

2-9

 in the 

terminal.
