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, getfacl also displays the default ACL.  Non-directo‐
       ries 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  repre‐
       senting  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  af‐
       fected  by  the  effective rights mask; all other entries are.)  Lines 11--15 display the de‐
       fault 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 in‐
       clude an effective rights comment for lines where the rights of the entry differ from the ef‐
       fective 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 di‐
       rectory 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, others).

       -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 ef‐
           fective 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  capi‐
           talized. 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 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.


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  de‐
       fault  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 indicating the  se‐
       tuid, setgid, and sticky bits are generated.
