Установить разрешения для будущих папок и файлов

У меня проблемы с управлением разрешениями в папке и соответствующих подпапках.

  • Я работаю над Ubuntu 14.04.
  • У меня есть программное обеспечение, которое периодически создает новые папки и файлы внутри главной папки.

Например, у меня есть главная папка /media/Folder и программное обеспечение создает папку / media / Folder / First_Folder. Когда он создает новую папку, у нее нет прав на запись для группы и для других пользователей. Вот вывод команды ls -al: drwxr-xr-x. Программное обеспечение также создает другие папки внутри предыдущей, например /media/Folder/First_Folder/Second_Folder1, /media/Folder/First_Folder/Second_Folder2 и т. Д.

Мне нужно иметь полные разрешения во всех подпапках и файлах, также только что сгенерированных. Я попытался рекурсивно изменить разрешения с помощью команды: sudo chmod 777 -R /media/Folder, но когда создаются новые папки, у них снова нет разрешений. После этого я попытался изменить ACL, но я не очень уверен в них. Вот мой экран getfacl:

file: Folder/
# owner: ubuntu
# group: ubuntu
# user::rwx
group::rwx
other::rwx

Как вы можете видеть, мой владелец и группа - это Ubuntu: Ubuntu. Затем я пытаюсь изменить ACL, используя команду:

sudo setfacl -Rdm g:ubuntu:rwx /media/Folder/

, и теперь экран становится таким:

# file: Folder/
# owner: ubuntu
# group: ubuntu
user::rwx
group::rwx
other::rwx
default:user::rwx
default:group::rwx
default:group:ubuntu:rwx
default:mask::rwx
default:other::rwx

, что выглядит хорошо. Но если я создаю новую папку внутри нее, экран getfacl выглядит так:

# file: Folder//First_Folder
# owner: ubuntu
# group: ubuntu
user::rwx
group::r-x
group:ubuntu:rwx
mask::rwx
other::r-x
default:user::rwx
default:group::rwx
default:group:ubuntu:rwx
default:mask::rwx
default:other::rwx

Как вы можете видеть строку с 5 и 8, она пропускает разрешение на запись. Как я могу иметь все разрешения? Я имею в виду и будущие папки и файлы.

PS Я попробовал также запустить команды: sudo setfacl -Rdm o::rwx /media/Sources/Previsioni/ и sudo setfacl -Rdm g::rwx /media/Sources/Previsioni/.

Вот мой etc / fstab:

# /etc/fstab: static file system information.
#

# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

# /etc/login.defs - Configuration control definitions for the login package.
#
# Three items must be defined:  MAIL_DIR, ENV_SUPATH, and ENV_PATH.
# If unspecified, some arbitrary (and possibly incorrect) value will
# be assumed.  All other items are optional - if not specified then
# the described action or option will be inhibited.

#   Directory where mailboxes reside, _or_ name of file, relative to the
#   home directory.  If you _do_ define MAIL_DIR and MAIL_FILE,
#   MAIL_DIR takes precedence.
#
#   Essentially:
#      - MAIL_DIR defines the location of users mail spool files
#        (for mbox use) by appending the username to MAIL_DIR as defined
#        below.
#      - MAIL_FILE defines the location of the users mail spool files as the
#        fully-qualified filename obtained by prepending the user home
#        directory before $MAIL_FILE
#
# NOTE: This is no more used for setting up users MAIL environment variable
#       which is, starting from shadow 4.0.12-1 in Debian, entirely the
#       job of the pam_mail PAM modules
#       See default PAM configuration files provided for
#       login, su, etc.

Вы просите, чтобы, когда когда-либо Вы создаете файл или каталог, те автоматически присвоили полномочия по умолчанию, установленные Вами.

umask 000 #put it in .bashrc file
  • umask инверсия chmod.
  • chmod используется для предоставления полномочий.
  • umask используется для отмены полномочий.

umask 000 означает Ваш, дают будущие файлы 666 и каталоги 777 полномочия.

значением по умолчанию 022 присвоен, что означает chmod 755.
