Name

getfacl - get file access control lists

Synopsis

getfacl [-adceEsRY5Pvh] file ...

getfacl [-adceEsRY5Pvh] -

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. Files 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 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 traditional file permission bits. These three are called the base 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.) Lines 10--14 display the default ACL associated with this directory. Directories may, but need not have a default ACL. Files never have a default ACL. Default ACL entries are governed by the same rules as ACL entries.

The default bahavior 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.

The ACL listings of multiple files are separated by blank lines. The output of getfacl can be used as input to setfacl.

Options

-a
Display the file access control list.
-d
Display the default access control list.
-c
Do not display the comment header (the first three lines of each file's output).
-e
Print all effective rights comments, even if identical to the ACL entry's rights.
-E
Do not print effective rights comments.
-s
Skip files that only have the base ACL entries (owner, group, others).
-R
List the ACLs of all files and directories recursively.
-Y
Follow symbolic links. The usual behavior is to skip symbolic links in subdirectories.
-5
Print output in post-order. This option exists mainly for compatibility reasons with setfacl.
-P
Do not strip leading slash characters (`/'). The default behavior is to strip leading slashes, so that an ACL listing can be easily applied to a different directory sub-tree (Yes, setfacl can do this).
-v
Print the version of getfacl and exit.
-h
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.

Posix Draft Compatibility

If the environment variable POSIXLY_CORRECT is defined, the default behavior of getfacl changes in the following way: Unless otherwise specified, only the ACL is printed. The default ACL is only printed if the -d option is given.
