J'ai presque dix ans de retard, mais voici ma réponse en utilisant Python.
Dans le .gif
ci-dessous, j'ai lancé le programme à partir d'un terminal existant avec l'enregistreur d'écran en cours d'exécution pour montrer à quoi il ressemblerait à la connexion :
J'ai écrit un programme Python pour cette réponse. Il y a quelques fonctionnalités supplémentaires qui ne sont pas demandées par le PO mais qui me sont utiles :
- S'exécute au démarrage automatique pour configurer les applications GUI fréquemment utilisées après la connexion.
- Ouvre plusieurs
gnome-terminal
onglets.
- Attribuer un titre aux onglets du terminal.
- Déplace Windows à la position préférée sur le bureau.
- Ouvre
gedit
et les cinq derniers fichiers ouverts dans des onglets séparés.
Le programme Python :
#!/usr/bin/env python
# -*- coding: utf-8 -*-

Notez que vous devrez peut-être modifier la variable BASHRC_TIME
sur votre système pour rendre le programme plus rapide. J'ai beaucoup de fonctions qui tournent dans mon ~/.bashrc
et le vôtre pourrait fonctionner beaucoup plus vite.
J'ai prévu d'écrire ceci depuis de nombreuses années, mais je ne l'ai jamais fait jusqu'à maintenant.
