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, 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: 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 permissions are not affected by the effective rights mask; all
other entries are.) Lines 10--14 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 con-
taining 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 out-
put).

--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, others).

-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 encountered in subdirectories.

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

--tabular
Use an alternative tabular output format. The ACL and the default ACL are dis-
played 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.

--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 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 -’’.
