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-directories
      cannot have default ACLs.

      If  getfacl is used on a file system that does not support ACLs, getfacl displays the access per‐
      missions 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 oth‐
      erwise, so it will not be shown for most files. (See CONFORMANCE TO  POSIX  1003.1e  DRAFT  STAN‐
      DARD 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 ef‐
      fective 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.

  PERMISSIONS
      Process  with  search access to a file (i.e., processes with read access to the containing direc‐
      tory of a file) are also granted read access to the file's ACLs.  This is analogous to  the  per‐
      missions 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 en‐
          try.

      -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  sym‐
          bolic  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 ar‐
          guments.  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 displayed in cap‐
          ital 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  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 indicating the setuid, setgid, and sticky
      bits are generated.
