CentOS 7.0 - man page for nfs4_editfacl (centos section 1)

NFS4_SETFACL(1) 		    NFSv4 Access Control Lists			  NFS4_SETFACL(1)

       nfs4_setfacl, nfs4_editfacl - manipulate NFSv4 file/directory access control lists

       nfs4_setfacl [OPTIONS] COMMAND file...
       nfs4_editfacl [OPTIONS] file...

       nfs4_setfacl  manipulates  the  NFSv4  Access  Control List (ACL) of one or more files (or
       directories), provided they are on a mounted NFSv4 filesystem which supports ACLs.

       nfs4_editfacl is equivalent to nfs4_setfacl -e.

       Refer to the nfs4_acl(5) manpage for information about NFSv4 ACL terminology and syntax.

       -a acl_spec [index]
	      add the ACEs from acl_spec to file's  ACL.   ACEs  are  inserted	starting  at  the
	      indexth position (DEFAULT: 1) of file's ACL.

       -A acl_file [index]
	      add the ACEs from the acl_spec in acl_file to file's ACL.  ACEs are inserted start-
	      ing at the indexth position (DEFAULT: 1) of file's ACL.

       -x acl_spec | index
	      delete ACEs matched from acl_spec - or delete the indexth ACE -  from  file's  ACL.
	      Note that the ordering of the ACEs in acl_spec does not matter.

       -X acl_file
	      delete  ACEs  matched from the acl_spec in acl_file from file's ACL.  Note that the
	      ordering of the ACEs in the acl_spec does not matter.

       -s acl_spec
	      set file's ACL to acl_spec.

       -S acl_file
	      set file's ACL to the acl_spec in acl_file.

       -e, --edit
	      edit file's ACL in the editor defined in the EDITOR environment variable	(DEFAULT:
	      vi(1))  and  set	the resulting ACL upon a clean exit, assuming changes made in the
	      editor were saved.  Note that if multiple files are specified, the editor  will  be
	      serially invoked once per file.

       -m from_ace to_ace
	      modify file's ACL in-place by replacing from_ace with to_ace.

       -?, -h, --help
	      display help text and exit.

	      display this program's version and exit.

       NOTE:  if  '-' is given as the acl_file with the -A/-X/-S flags, the acl_spec will be read
       from stdin.

       -R, --recursive
	      recursively apply to a directory's  files  and  subdirectories.	Similar  to  set-
	      facl(1),	the  default behavior is to follow symlinks given on the command line and
	      to skip symlinks encountered while recursing through directories.

       -L, --logical
	      in conjunction with -R/--recursive, a logical walk follows all symbolic links.

       -P, --physical
	      in conjunction with -R/--recursive, a physical walk skips all symbolic links.

	      display results of COMMAND, but do not save changes.

       With nfs4_setfacl, one can use simple abbreviations ("aliases") to express generic  "read"
       (R),  generic  "write" (W), and generic "execute" (X) permissions, familiar from the POSIX
       mode bits used by, e.g., chmod(1).  To use these aliases, one can put them in the  permis-
       sions field of an NFSv4 ACE and nfs4_setfacl will convert them: an R is expanded to rntcy,
       a W is expanded to watTNcCy (with D added to directory ACEs), and  an  X  is  expanded  to
       xtcy.   Please refer to the nfs4_acl(5) manpage for information on specific NFSv4 ACE per-

       For example, if one wanted to grant generic "read" and "write" access on a file, the NFSv4
       permissions  field  would  normally contain something like rwatTnNcCy.  Instead, one might
       use aliases to accomplish the same goal with RW.

       The two permissions not included in any of the aliases are d (delete) and o (write-owner).
       However,  they  can  still  be used: e.g., a permissions field consisting of Wdo expresses
       generic "write" access as well as the ability to delete and change ownership.

       Assume that the file `foo' has the following NFSv4 ACL for the following examples:


       - add ACE granting `alice@nfsdomain.org' generic "read" and "execute" access (defaults  to
	 prepending ACE to ACL):
	      $ nfs4_setfacl -a A::alice@nfsdomain.org:rxtncy foo

       - add the same ACE as above, but using aliases:
	      $ nfs4_setfacl -a A::alice@nfsdomain.org:RX foo

       - edit existing ACL in a text editor and set modified ACL on clean save/exit:
	      $ nfs4_setfacl -e foo

       - set ACL (overwrites original) to contents of a spec_file named `newacl.txt':
	      $ nfs4_setfacl -S newacl.txt foo

       - recursively set the ACLs of all files and subdirectories in the current directory, skip-
	 ping all symlinks encountered, to the ACL contained in the spec_file named `newacl.txt':
	      $ nfs4_setfacl -R -P -S newacl.txt *

       - delete the first ACE, but only print the resulting ACL (does not save changes):
	      $ nfs4_setfacl --test -x 1 foo

       - delete the last two ACEs above:
	      $ nfs4_setfacl -x "A::EVERYONE@rtncy, D::EVERYONE@:waxTC" foo

       - modify (in-place) the second ACE above:
	      $ nfs4_setfacl -m D::OWNER@:x  D::OWNER@:xo foo

       - set ACLs of `bar' and `frobaz' to ACL of `foo':
	      $ nfs4_getfacl foo | nfs4_setfacl -S - bar frobaz

       nfs4_setfacl was written by people at CITI, the Center for Information Technology Integra-
       tion (http://www.citi.umich.edu).  This manpage was written by David Richter.
