.TH GETFACL 1 "ACL File Utilities" "May 2000" "Access Control Lists"

.SH NAME

getfacl \- get file access control lists

.SH SYNOPSIS

.B getfacl

[\-aceEsRLPtpndvh] file ...

.B getfacl

[\-aceEsRLPtpndvh] \-

.SH 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:

.fam C

.RS

.nf

 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::\-\-\-

.fi

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

included 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 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 11\-\-15 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 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.

.SS 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.

.SH OPTIONS

.TP 4

.I \-a, \-\-access

Display the file access control list.

.TP

.I \-d, \-\-default

Display the default access control list.

.TP

.I \-c, \-\-omit-header

Do not display the comment header (the first three lines of each file's output).

.TP

.I \-e, \-\-all-effective

Print all effective rights comments, even if identical to the rights defined by the ACL entry.

.TP

.I \-E, \-\-no-effective

Do not print effective rights comments.

.TP

.I \-s, \-\-skip-base

Skip files that only have the base ACL entries (owner, group, others).

.TP

.I \-R, \-\-recursive

List the ACLs of all files and directories recursively.

.TP

.I \-L, \-\-logical

Logical walk, follow symbolic links to directories. The default behavior is to follow

symbolic link arguments, and skip symbolic links encountered in subdirectories.

Only effective in combination with \-R.

.TP

.I \-P, \-\-physical

Physical walk, do not follow symbolic links to directories. This also skips symbolic

link arguments.

Only effective in combination with \-R.

.TP

.I \-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.

.TP

.I \-p, \-\-absolute-names

Do not strip leading slash characters (`/'). The default behavior is to

strip leading slash characters.

.TP

.I \-n, \-\-numeric

List numeric user and group IDs

.TP

.I \-v, \-\-version

Print the version of getfacl and exit.

.TP

.I \-h, \-\-help

Print help explaining the command line options.

.TP

.I \-\-

End of command line options. All remaining parameters are interpreted as file names, even if they start with a dash character.

.TP

.I \-

If the file name parameter is a single dash character, getfacl reads a list of files from standard input.

.SH 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

.I \-d

option is given. If no command line parameter is given,

.I getfacl

behaves as if it was invoked as ``getfacl \-''.

No flags comments indicating the setuid, setgit, and sticky bits are generated.
