GETFACL(1)                   Access Control Lists                   GETFACL(1)




NAME

       getfacl - get file access control lists


SYNOPSIS

       getfacl [-dRLPvh] file ...

       getfacl [-dRLPvh] -



DESCRIPTION

       For  each  file,  getfacl displays the file name, owner, the group, and
       the Access Control List (ACL). If a directory has a default  ACL,  get-
       facl also displays the default ACL. Non-directories cannot have default
       ACLs.

       If getfacl is used on a file system that does not support ACLs, getfacl
       displays  the  access  permissions defined by the traditional file mode
       permission bits.

       The output format of getfacl is as follows:
               1:  # file: somedir/
               2:  # owner: lisa
               3:  # group: staff
               4:  user::rwx
               5:  user:joe:rwx               #effective:r-x
               6:  group::rwx                 #effective:r-x
               7:  group:cool:r-x
               8:  mask:r-x
               9:  other:r-x
              10:  default:user::rwx
              11:  default:user:joe:rwx       #effective:r-x
              12:  default:group::r-x
              13:  default:mask:r-x
              14:  default:other:---


       Lines 4, 6 and 9 correspond to the user, group and other fields of  the
       file mode permission bits. These three are called the base ACL entries.
       Lines 5 and 7 are named user and named group entries.  Line  8  is  the
       effective  rights  mask. This entry limits the effective rights granted
       to all groups and to named users. (The file owner  and  others  permis-
       sions  are not affected by the effective rights mask; all other entries
       are.)  Lines 10--14 display the default ACL associated with this direc-
       tory.  Directories  may  have a default ACL. Regular files never have a
       default ACL.

       The default behavior for getfacl is to display both  the  ACL  and  the
       default ACL, and to include an effective rights comment for lines where
       the rights of the entry differ from the effective rights.

       If output is to a terminal, the effective rights comment is aligned  to
       column  40.  Otherwise,  a single tab character separates the ACL entry
       and the effective rights comment.

       The ACL listings of multiple files are separated by blank  lines.   The
       output of getfacl can also be used as input to setfacl.


   PERMISSIONS
       Process  with search access to a file (i.e., processes with read access
       to the containing directory of a file) are also granted read access  to
       the  file’s  ACLs.   This  is analogous to the permissions required for
       accessing the file mode.


   OPTIONS
       --access
           Display the file access control list.

       -d, --default
           Display the default access control list.

       --omit-header
           Do not display the comment header (the first three  lines  of  each
           file’s output).

       --all-effective
           Print  all  effective  rights  comments,  even  if identical to the
           rights defined by the ACL entry.

       --no-effective
           Do not print effective rights comments.

       --skip-base
           Skip files that only have the base ACL entries (owner, group,  oth-
           ers).

       -R, --recursive
           List the ACLs of all files and directories recursively.

       -L, --logical
           Logical  walk,  follow  symbolic  links. The default behavior is to
           follow symbolic link arguments, and to skip symbolic links  encoun-
           tered in subdirectories.

       -P, --physical
           Physical  walk,  skip  all symbolic links. This also skips symbolic
           link arguments.

       --tabular
           Use an alternative tabular output format. The ACL and  the  default
           ACL  are  displayed  side by side. Permissions that are ineffective
           due to the ACL mask entry are displayed capitalized. The entry  tag
           names  for the ACL_USER_OBJ and ACL_GROUP_OBJ entries are also dis-
           played in capital letters, which helps in spotting those entries.

       --absolute-names
           Do not strip leading slash characters (‘/’). The  default  behavior
           is to strip leading slash characters.

       --version
           Print the version of getfacl and exit.

       --help
           Print help explaining the command line options.

       --  End  of  command  line options. All remaining parameters are inter-
           preted as file names, even if they start with a dash character.

       -   If the file name parameter is  a  single  dash  character,  getfacl
           reads a list of files from standard input.



CONFORMANCE TO POSIX 1003.1e DRAFT STANDARD 17

       If  the  environment  variable  POSIXLY_CORRECT is defined, the default
       behavior of getfacl changes in the  following  ways:  Unless  otherwise
       specified,  only the ACL is printed. The default ACL is only printed if
       the -d option is given. If no command line parameter is given,  getfacl
       behaves as if it was invoked as ‘‘getfacl -’’.
