Description

On Ubuntu and MacOS, they use "" character for line truncations of a long command.
But the problem is that on Windows, we use "^" character for line truncations on Command Prompt Tool and "`" character on Powershell Tool. Most users like to copy the whole lines of command without editing when they first approach this project.
More detailed description can be found in the issue below.
