5 NAME
   6        setfacl - modify the Access Control List (ACL) for a file or files
   7 
   8 SYNOPSIS
   9        setfacl [-r] -s acl_entries file
  10 
  11 
  12        setfacl [-r] -md acl_entries file
  13 
  14 
  15        setfacl [-r] -f acl_file file
  16 
  17 
  18 DESCRIPTION
  19        For each file specified, setfacl either replaces its entire ACL,
  20        including the default ACL on a directory, or it adds, modifies, or
  21        deletes one or more ACL entries, including default entries on
  22        directories.
  23 
  24 






  25        When the setfacl command is used, it can result in changes to the file
  26        permission bits. When the user ACL entry for the file owner is changed,
  27        the file owner class permission bits are modified. When the group ACL
  28        entry for the file group class is changed, the file group class
  29        permission bits are modified. When the other ACL entry is changed, the
  30        file other class permission bits are modified.
  31 
  32 
  33        If you use the chmod(1) command to change the file group owner
  34        permissions on a file with ACL entries, both the file group owner
  35        permissions and the ACL mask are changed to the new permissions. Be
  36        aware that the new ACL mask permissions can change the effective
  37        permissions for additional users and groups who have ACL entries on the
  38        file.
  39 
  40 
  41        A directory can contain default ACL entries. If a file or directory is
  42        created in a directory that contains default ACL entries, the newly
  43        created file has permissions generated according to the intersection of
  44        the default ACL entries and the permissions requested at creation time.

 265 
 266 
 267        The following example sets the same ACL on file abc as the file xyz.

 269 
 270          getfacl xyz | setfacl -f - abc

   5 NAME
   6        setfacl - modify the Access Control List (ACL) for a file or files
   7 
   8 SYNOPSIS
   9        setfacl [-r] -s acl_entries file
  10 
  11 
  12        setfacl [-r] -md acl_entries file
  13

  15        setfacl [-r] -f acl_file file

  18 DESCRIPTION
  19        For each file specified, setfacl either replaces its entire ACL,
  20        including the default ACL on a directory, or it adds, modifies, or
  21        deletes one or more ACL entries, including default entries on
  22        directories.
  23 
  24 
  25        The setfacl utility can only manipulate POSIX-draft ACLs.  See acl(5)
  26        for a description of the difference between the older POSIX-draft ACLs
  27        and the newer NFSv4 ACLs.  The chmod(1) utility can be used to
  28        manipulate ACLs on all types of file system.
  29 
  30 
  31        When the setfacl command is used, it can result in changes to the file
  32        permission bits. When the user ACL entry for the file owner is changed,
  33        the file owner class permission bits are modified. When the group ACL
  34        entry for the file group class is changed, the file group class
  35        permission bits are modified. When the other ACL entry is changed, the
  36        file other class permission bits are modified.
  37 
  38 
  39        If you use the chmod(1) command to change the file group owner
  40        permissions on a file with ACL entries, both the file group owner
  41        permissions and the ACL mask are changed to the new permissions. Be
  42        aware that the new ACL mask permissions can change the effective
  43        permissions for additional users and groups who have ACL entries on the
  44        file.
  45 
  46 
  47        A directory can contain default ACL entries. If a file or directory is
  48        created in a directory that contains default ACL entries, the newly
  49        created file has permissions generated according to the intersection of
  50        the default ACL entries and the permissions requested at creation time.
