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,  get-
       facl 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 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  permis-
       sions  are not affected by the effective rights mask; all other entries
       are.)  Lines 11--15 display the default ACL associated with this direc-
       tory.  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.


   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.


   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
	   behavior 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 dis-
	   played 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
       behavior of getfacl changes in the  following  ways:  Unless  otherwise
       specified,  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 indi-
       cating the setuid, setgit, and sticky bits are generated.
