如何通过 VSCode 终端 API 以字符串形式获取输出？

Question

VSCode has a Windows API that allows interaction with the terminal.

For example, you can send the Linux command pwd & the command output may be /usr/home/userName

I have tried writing the output to disk & then reading it later by using something like pwd > directory.txt ;

terminal.sendText(`pwd > directory.txt`);

This seems to work, but I was wondering if there was something more elegant.

//Create a new terminal
let terminal = vscode.window.createTerminal(`Name of terminal`, 'C:\path\to\terminal\shell\shell.exe');

// send command to newly created terminal
terminal.sendText(`pwd`);

I know for sure the code above works because I can write the outputs to a file using;

terminal.sendText(`pwd > directory.txt`);

So the question is, how do I get the outputs of terminal.sendText() as a string without having to first write them to disk?

vscode also provides an event to listen to any data being written to the terminal, use the following code to listen to the terminal write :

vscode.window.onDidWriteTerminalData((e) => {console.log(e.data)})

but it'll listen for all the writes, so you'll have to put in some conditonals to prevent reading every keystroke on the terminal, maybe you can read only when e.data == \\n or other conditions.
