getfacl - get file access control lists


getfacl [-aceEsRLPtpndvh] file ...

getfacl [-aceEsRLPtpndvh] -


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

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

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.


-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.


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, setgit, and sticky bits are generated.
