Je viens de le rencontrer moi-même et la cp
commande intégrée le gère.
J'ai découvert un tas de vieilles cartes CF dont je voulais récolter les photos. Mes scripts de traitement regarderont le fichier mtime pour le mettre au bon endroit, donc j'avais besoin qu'il soit conservé.
Depuis la page de manuel :
-p Cause cp to preserve the following attributes of each source file in the copy: modification time,
access time, file flags, file mode, user ID, and group ID, as allowed by permissions. Access
Control Lists (ACLs) and Extended Attributes (EAs), including resource forks, will also be pre-
served.
If the user ID and group ID cannot be preserved, no error message is displayed and the exit value
is not altered.
If the source file has its set-user-ID bit on and the user ID cannot be preserved, the set-user-
ID bit is not preserved in the copy's permissions. If the source file has its set-group-ID bit
on and the group ID cannot be preserved, the set-group-ID bit is not preserved in the copy's per-
missions. If the source file has both its set-user-ID and set-group-ID bits on, and either the
user ID or group ID cannot be preserved, neither the set-user-ID nor set-group-ID bits are pre-
served in the copy's permissions.
Donc, en utilisant, zsh
j'ai pu exécuter ( NO NAME
étant le nom du volume de mes cartes):
cp -rvp /Volumes/NO\ NAME/DCIM/**/*.{JPG,jpg} ~/Desktop/tmp/pics
Je crois que la /**/*
construction spéciale est spécifique à ZSH; mais vous pourriez faire quelque chose comme
find /Volumes/WHATEVER -type d -print0 | xargs cp -vp {}/*.JPG /my/out/path
