Ho sempre aperto il mio terminale (Fedora 22), perché tutto il mio lavoro lo faccio da lì. A volte cerco alcune informazioni nel browser o semplicemente mi diverto. Dopo 20-30 minuti di navigazione (il browser non si avvia dalla riga di comando) torno al terminale e ho visto qualcosa di strano - era in tutte le schede del terminale:

mostra il comando?
