MySQL - en console : sortie en fiches plutôt qu'en liste

Le client MySQL en ligne de commandes est décidément puissant ...

Vous avez peut-être déjà été confrontés à la difficulté de lecture de résultats contenant de nombreuses colonnes ...
Exemple :

mysql> SHOW SLAVE STATUS;

... 

Dans ce cas, il vous suffit de remplacer le ; en fin de commande par \G pour obtenir une sortie en "fiches" :

mysql> SHOW SLAVE STATUS\G
