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:
45 either the letter representing the bit, or else a dash (-). This line
46 is included if any of those bits is set and left out otherwise, so it
47 will not be shown for most files. (See CONFORMANCE TO POSIX 1003.1e
48 DRAFT 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
53 effective rights mask. This entry limits the effective rights granted
54 to all groups and to named users. (The file owner and others permis‐
55 sions are not affected by the effective rights mask; all other entries
56 are.) Lines 11--15 display the default ACL associated with this direc‐
57 tory. Directories may have a default ACL. Regular files never have a
58 default ACL.
59 The default behavior for getfacl is to display both the ACL and the
61 default 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
76 accessing the file mode.
77 OPTIONS
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
106 behavior 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
144 behavior of getfacl changes in the following ways: Unless otherwise
145 specified, only the ACL is printed. The default ACL is only printed if
146 the -d option is given. If no command line parameter is given, getfacl
147 behaves as if it was invoked as ``getfacl -''. No flags comments indi‐
148 cating the setuid, setgit, and sticky bits are generated.
