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
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, others).
-R, --recursive
List the ACLs of all files and directories recur
sively.
-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 arguments.
--tabular
Use an alternative tabular output format. The ACL and
the default ACL are displayed side by side. Permis
sions that are ineffective due to the ACL mask entry
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 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 -''.
