coffee:tldr:888d6

This command is used in a command-line interface to execute a specific task related to a programming language called CoffeeScript. Let's break it down:

• coffee: This is a command that invokes the CoffeeScript compiler. It allows you to compile CoffeeScript code into JavaScript.
• --watch: This is an option provided by the CoffeeScript compiler. When used, it instructs the compiler to watch for changes in the specified files and automatically recompile them whenever a file is modified.
• ${filename-coffee}: This is called a template variable or placeholder. In this command, it represents the name of the CoffeeScript file you want to watch. You are supposed to replace ${filename-coffee} with the actual filename of your CoffeeScript file.

So when you run the command coffee --watch ${filename-coffee}, the CoffeeScript compiler will start watching the specified CoffeeScript file for any changes. If there are any modifications, it will recompile the file into JavaScript automatically.
