coffee:tldr:7a11f
This command is using the Coffeescript programming language syntax.
In this command, coffee
is a command line tool used to run Coffeescript code.
The ${filename-coffee}
part is an example of a substitution or variable expansion. It is typically used in command line interfaces to dynamically replace the value of a variable.
In this case, it suggests that ${filename-coffee}
is a variable representing the name of a Coffeescript file. So, when executing the command, ${filename-coffee}
will be replaced with the actual filename of the Coffeescript file you want to run.
For example, if you have a file named script.coffee
and you run the command coffee script.coffee
, ${filename-coffee}
will be replaced with script.coffee
, and the command executed will be coffee script.coffee
.
This approach allows you to run Coffeescript files with different names by simply changing the value of the ${filename-coffee}
variable in the command.
