Contrario a lo que Gemini dice, mega-cmd sí permite especificar los permisos que quieres en tus syncs.
Usage: permissions [(--files|--folders) [-s XXX]]
Shows/Establish default permissions for files and folders created by MEGAcmd.
Permissions are unix-like permissions, with 3 numbers: one for owner, one for group and one for others
Options:
--files To show/set files default permissions.
--folders To show/set folders default permissions.
--s XXX To set new permissions for newly created files/folder.
Notice that for files minimum permissions is 600,
for folders minimum permissions is 700.
Further restrictions to owner are not allowed (to avoid missfunctioning).
Notice that permissions of already existing files/folders will not change.
Notice that permissions of already existing files/folders will not change.
Notice: this permissions will be saved for the next time you execute MEGAcmd server. They will be removed if you logout.
Luego entonces, si quieres que tus archivos sean escribibles por el grupo, le das permissions --files -s 664 y permissions --folders -s 775. O 660 y 770 si quieres, tú como quieras.
Esto es útil para mí como mi estrategia de respaldo y sincronización de configuración de servidores mediante Mega.
