turbo:tldr:bc3b1
This command is utilizing the "turbo" tool to execute a task specified by the variable "${task_name}".
The "--graph" flag is used to provide a graph file as input to the task. The "${filename}" variable represents the name of the graph file, while the "${select}" variable represents the file format or extension of the graph file.
The command will replace "${filename}.${select}" with the actual filename and file extension you want to use, creating a complete filename for the graph file.
For example, if the values of "${task_name}", "${filename}", and "${select}" are "task1", "example", and "txt" respectively, the command will be interpreted as:
turbo run task1 --graph=example.txt
This will execute the "task1" task, passing the "example.txt" graph file as input to it.
