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 in-
cluded 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 ef-
fective 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. Di-
rectories 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 de-
fault 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 ac-
cessing 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, oth-
ers).
-R, --recursive
List the ACLs of all files and directories recursively.
-L, --logical
Logical walk, follow symbolic links to directories. The default be-
havior 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 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 be-
havior of getfacl changes in the following ways: Unless otherwise speci-
fied, 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.
