terminale sintassi SSH in Debian / Ubuntu

postato su di

L'uso di sintassi colorata nel terminale SSH in Debian e Ubuntu è disattivato per default.
Kolorowanie składni bardzo pomaga w szybkim rozróżnianiu tekstu oraz ułatwia sprawnie i szybko zarządzać i administrować.

Aby włączyć kolorowanie składni, zastępujemy /root/.bashrc lub /home/użytkownik/.bashrc skryptem który jest poniżej.
Jest to właściwie troszkę rozszerzona wersja.

1
sudo nano /root/.bashrc

1
sudo nano /home/użytkownik/.bashrc
