ld:tldr:84a71

This command uses the "ld" command-line program to link object files and create an executable file. Here's a breakdown of the command:

• "ld": This is the command itself, which invokes the linker program.
• "${filename-o}": This represents the input object file that needs to be linked. The "$" and "{}" are used for variable substitution, so you should replace "${filename-o}" with the actual file name and path of the object file. The "-o" flag indicates the output file name.
• "--output": This specifies the flag that follows as the name of the output file.
• "${path-to-output_executable}": This represents the path and name of the output executable file. Again, replace "${path-to-output_executable}" with the desired file name and path.

Overall, this command takes an input object file (specified by "${filename-o}"), invokes the linker ("ld"), and generates an executable file with a specified name and path ("${path-to-output_executable}").
