GETFACL(1)                    Access Control Lists                    GETFACL(1)



NAME
       getfacl - get file access control lists

SYNOPSIS
       getfacl [-aceEsRLPtpndvh] file ...

       getfacl [-aceEsRLPtpndvh] -


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, getfacl 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:  # flags: -s-
               5:  user::rwx
               6:  user:joe:rwx               #effective:r-x
               7:  group::rwx                 #effective:r-x
               8:  group:cool:r-x
               9:  mask::r-x
              10:  other::r-x
              11:  default:user::rwx
              12:  default:user:joe:rwx       #effective:r-x
              13:  default:group::r-x
              14:  default:mask::r-x
              15:  default:other::---


       Lines 1--3 indicate the file name, owner, and owning group.

       Line 4 indicates the setuid (s), setgid (s), and sticky (t) bits: either
       the letter representing the bit, or else a dash (-). This line is
       included if any of those bits is set and left out otherwise, so it will
       not be shown for most files. (See CONFORMANCE TO POSIX 1003.1e DRAFT
       STANDARD 17 below.)

       Lines 5, 7 and 10 correspond to the user, group and other fields of the
       file mode permission bits. These three are called the base ACL entries.
       Lines 6 and 8 are named user and named group entries. Line 9 is the
       effective rights mask. This entry limits the effective rights granted to
       all groups and to named users. (The file owner and others permissions are
       not affected by the effective rights mask; all other entries are.)  Lines
       11--15 display the default ACL associated with this directory.
       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
       -a, --access
           Display the file access control list.

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

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

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

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

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

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

       -L, --logical
           Logical walk, follow symbolic links to directories. The default
           behavior is to follow symbolic link arguments, and skip symbolic
           links encountered in subdirectories.  Only effective in combination
           with -R.

       -P, --physical
           Physical walk, do not follow symbolic links to directories. This also
           skips symbolic link arguments.  Only effective in combination with
           -R.

       -t, --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 displayed in
           capital letters, which helps in spotting those entries.

       -p, --absolute-names
           Do not strip leading slash characters (`/'). The default behavior is
           to strip leading slash characters.

       -n, --numeric
           List numeric user and group IDs

       -v, --version
           Print the version of getfacl and exit.

       -h, --help
           Print help explaining the command line options.

       --  End of command line options. All remaining parameters are interpreted
           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 -''.  No flags comments
       indicating the setuid, setgid, and sticky bits are generated.
