15 For each file, getfacl displays the file name, owner, the group, and
16 the Access Control List (ACL). If a directory has a default ACL, get‐
17 facl also displays the default ACL. Non-directories cannot have default
18 ACLs.
19 If getfacl is used on a file system that does not support ACLs, getfacl
21 displays the access permissions defined by the traditional file mode
22 permission bits.
23 The output format of getfacl is as follows:
25 1: # file: somedir/
26 2: # owner: lisa
27 3: # group: staff
28 4: # flags: -s-
29 5: user::rwx
30 6: user:joe:rwx #effective:r-x
31 7: group::rwx #effective:r-x
32 8: group:cool:r-x
33 9: mask::r-x
34 10: other::r-x
35 11: default:user::rwx
36 12: default:user:joe:rwx #effective:r-x
37 13: default:group::r-x
38 14: default:mask::r-x
39 15: default:other::---
40 Lines 1--3 indicate the file name, owner, and owning group.
43 Line 4 indicates the setuid (s), setgid (s), and sticky (t) bits: ei‐
45 ther the letter representing the bit, or else a dash (-). This line is
46 included if any of those bits is set and left out otherwise, so it will
47 not be shown for most files. (See CONFORMANCE TO POSIX 1003.1e DRAFT
48 STANDARD 17 below.)
49 Lines 5, 7 and 10 correspond to the user, group and other fields of the
51 file mode permission bits. These three are called the base ACL entries.
52 Lines 6 and 8 are named user and named group entries. Line 9 is the ef‐
53 fective rights mask. This entry limits the effective rights granted to
54 all groups and to named users. (The file owner and others permissions
55 are not affected by the effective rights mask; all other entries are.)
56 Lines 11--15 display the default ACL associated with this directory.
57 Directories may have a default ACL. Regular files never have a default
58 ACL.
59 The default behavior for getfacl is to display both the ACL and the de‐
61 fault ACL, and to include an effective rights comment for lines where
62 the rights of the entry differ from the effective rights.
63 If output is to a terminal, the effective rights comment is aligned to
65 column 40. Otherwise, a single tab character separates the ACL entry
66 and the effective rights comment.
67 The ACL listings of multiple files are separated by blank lines. The
69 output of getfacl can also be used as input to setfacl.
70 PERMISSIONS
73 Process with search access to a file (i.e., processes with read access
74 to the containing directory of a file) are also granted read access to
75 the file's ACLs. This is analogous to the permissions required for ac‐
76 cessing the file mode.
77
80 -a, --access
81 Display the file access control list.
82 -d, --default
84 Display the default access control list.
85 -c, --omit-header
87 Do not display the comment header (the first three lines of each
88 file's output).
89 -e, --all-effective
91 Print all effective rights comments, even if identical to the
92 rights defined by the ACL entry.
93 -E, --no-effective
95 Do not print effective rights comments.
96 -s, --skip-base
98 Skip files that only have the base ACL entries (owner, group, oth‐
99 ers).
100 -R, --recursive
102 List the ACLs of all files and directories recursively.
103 -L, --logical
105 Logical walk, follow symbolic links to directories. The default be‐
106 havior is to follow symbolic link arguments, and skip symbolic
107 links encountered in subdirectories. Only effective in combination
108 with -R.
109 -P, --physical
111 Physical walk, do not follow symbolic links to directories. This
112 also skips symbolic link arguments. Only effective in combination
113 with -R.
114 -t, --tabular
116 Use an alternative tabular output format. The ACL and the default
117 ACL are displayed side by side. Permissions that are ineffective
118 due to the ACL mask entry are displayed capitalized. The entry tag
119 names for the ACL_USER_OBJ and ACL_GROUP_OBJ entries are also dis‐
120 played in capital letters, which helps in spotting those entries.
121 -p, --absolute-names
123 Do not strip leading slash characters (`/'). The default behavior
124 is to strip leading slash characters.
125 -n, --numeric
127 List numeric user and group IDs
128 -v, --version
130 Print the version of getfacl and exit.
131 -h, --help
133 Print help explaining the command line options.
134 -- End of command line options. All remaining parameters are inter‐
136 preted as file names, even if they start with a dash character.
137 - If the file name parameter is a single dash character, getfacl
139 reads a list of files from standard input.
140
143 If the environment variable POSIXLY_CORRECT is defined, the default be‐
144 havior of getfacl changes in the following ways: Unless otherwise spec‐
145 ified, only the ACL is printed. The default ACL is only printed if the
146 -d option is given. If no command line parameter is given, getfacl be‐
147 haves as if it was invoked as ``getfacl -''. No flags comments indi‐
148 cating the setuid, setgid, and sticky bits are generated.
