Supprimer les plus vieux fichiers d’un dossier tant qu’on dépasse une certaine taille
Exemples de lancement du script
Notez qu’il faut lancer en utilisant « source«
- Supprimer les plus vieux fichiers du dossier courant (
./) tant qu’il prend plus de 96Mo :
source ./clean_custom.sh --path ./ -l 9600000 - Supprimer les plus vieux fichiers du dossier temporaire (
/tmp/) tant qu’il prend plus de 2Go :
source ./clean_custom.sh --path /tmp/ -l 2000000000
