Is there a way to launch a terminal window (or cmd on Windows) and pass/run a command?

问题

Question

Is it possible to do the following?

open a new cmd.exe or terminal (on MacOS / Linux) window
pass / run a command, e.g. cd <path>

Problem

I can open cmd by running this command:

"$electron.shell.openItem('cmd.exe')"

But shell.openItem doesn't allow to pass the arguments / commands.

I tried using child_process but I couldn't make it work at all, it doesn't open a new terminal window:

const { spawn, exec } = require('child_process');
spawn('C:/Windows/System32/cmd.exe');

I also tried running the following command, but still nothing:

spawn( 'cmd.exe', [ '/c', 'echo ASDASD' ], { stdio: [0, 1, 2] } )

The only possible solution that I see is to create a command.bat:

start cmd.exe /K "cd /D C:\test"

And then use openItem:

"$electron.shell.openItem('command.bat')"

But that would only work on Windows

Here is a working example showing how to open a Terminal window at a specific path (~/Desktop for instance) on macOS, from a renderer script:

const { app } = require ('electron').remote;
const atPath = app.getPath ('desktop');
const { spawn } = require ('child_process');
let openTerminalAtPath = spawn ('open', [ '-a', 'Terminal', atPath ]);
openTerminalAtPath.on ('error', (err) => { console.log (err); });

It should be easy to adapt it to any selected atPath... As for running other commands, I haven't found a way yet...

And here is the equivalent working code for Linux Mint Cinnamon or Ubuntu:

const { app } = require ('electron').remote;
const terminal = 'gnome-terminal';
const atPath = app.getPath ('desktop');
const { spawn } = require ('child_process');
let openTerminalAtPath = spawn (terminal, { cwd: atPath });
openTerminalAtPath.on ('error', (err) => { console.log (err); });

Please note that the name of the terminal application may be different, depending on the Linux flavor (for instance 'mate-terminal' on Linux Mint MATE), and also that the full path to the application can be explicitly defined, to be on the safe side:

const terminal = '/usr/bin/gnome-terminal';

HTH...

Solution

I finally found a way to do it on Windows:

var child_process = require('child_process');
child_process.exec("start cmd.exe /K cd /D C:/test");

Notes

You have to add the word start to open a new command window
Instead of cd /D C:/test you can specify any other command, e.g. python
/D is to make sure it will change the current drive automatically, depending on the path specified
/K removes the initial message
Don't use execSync it will lock the app until the terminal (command prompt) window is closed

As for MacOS, looks like it's possible to do with osascript

osascript -e 'tell application "Terminal" to activate' -e 'tell application "System Events" to tell process "Terminal" to keystroke "t" using command down'
