How to Open a Command Terminal in Linux

How to write a shell script to open four terminals and execute a command in each?

You could use a "for" loop, and a "&" to run xterm in background:

---

#!/bin/bash

# some older test, doesn't work and complains and I get this message on command line: "QApplication::qAppName: Please instantiate the QApplication object first"
# I also can't enter text after command executes
#echo "Hello World!"
#exec konsole --noclose -e cat ~/.aliases

for i in 1 2 3 4
do
# opens terminal but then I can't control terminal afterwards
xterm -hold -e "echo Hello My World" &
done

# didn't do anything
#exit 0

# didn't do anything except make me type exit an extra time where I executed my shell script
#$SHELL

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

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...

How to kill all open terminals using command lines in CentOs

If you want to kill all open terminals except for the current one, you can use

kill $(pgrep bash)

pgrep bash lists the pids of all the active terminals

if the terminals refuse to die, you can use

kill -9 $(pgrep bash)

the "-9" is used to send the SIGKILL Signal to the process

How can I open the terminal in Visual Studio?

Visual Studio 2022/2019

Now Visual Studio has a built-in terminal:

Menu View → Terminal (Ctrl + ")

To change the default terminal

Menu Tools → Options → Terminal → Set As Default

Before Visual Studio 2019

From comments, the best answer is from Hans Passant.

1. Add an external tool.

   Menu Tools → External Tools → Add

   Title: Terminal (or name it yourself)

   Command = cmd.exe or Command = powershell.exe

   Arguments = /k

   Initial Directory = $(ProjectDir)

2. Menu Tools → Terminal (or whatever you put in title)

3. Enjoy!
