One-click: Open terminal, run commands, keep using the terminal

You need to specify what the terminal to do after executing the command source bin/activate. You want an active bash session so you need to run bash. In addition there is a mes with the quotes. So the script could be:

#!/usr/bin/env bash
konsole --noclose --workdir /my/work/dir/ -e 'bash -c "source bin/activate; exec bash"' &

• & at the end is added in order to keep the main terminal usable, in case you are executing that script from other terminal window.

• the exec command could be omitted, and you can use only bash.

Here are few answers of similar questions, dedicated to gnome-terminal:

• how can I open a extra console and run a program in it with one command?

• Open a new terminal and source scripts

• How to open one (or more) gnome-terminal window with few tabs, each with different profile, when start/reboot the computer?

I am not able to comment, but from what I understand I may suggest

#!/bin/bash
cd /my/work/dir/
source bin/activate
konsole
