CHECK_FOR_UPDATES

[Jean-Baptiste-Lasselle]

Réparer l' opération std d'update, en automatisant le "check for updates" :

• pouvoir répondre à la question y a t lil de nouvelles updates?
• Si la réponse est oui, générer un terraform , afficher le terraform plan, et demander confirmer, avant de faire le terraform apply / ( verson simple de testys : effectuer l'update ou la suite des updates successifs nécessaires, en linux bash )

• interface graphique ncurses / dialog :

  • Debian / Ubuntu :

sudo apt-get install -y dialog

• Cent OS :

sudo apt-get install -y dialog

Debian

• Afficher toutes les "upgrades" disponibles :

sudo apt-get -V -s dist-upgrade \
    |grep -E "^   .*=>.*" \
    |awk 'BEGIN {
        ul=sprintf("%*s",40,""); gsub(/ /,"-",ul);
        printf "%-30s %-30s %-30s\n", "Package", "Installed", "Available";
        printf "%-30.30s %-30.30s %-30.30s\n", ul, ul, ul;
     }
     {
        printf "%-30s %-30s %-30s\n",
               $1,
               substr($2,2),
               substr($4,1,length($4)-1)
     }'
