If the -H/--more-help flag is specified, nfs4_getfacl will print some information about NFSv4 ACLs and the fields used in ACEs.
If the -R/--recursive flag is specified, nfs4_getfacl will list the NFSv4 ACLs of all files and directories recursively.
If the -c/--omit-header flag is specified, nfs4_getfacl will not display the comment header (Do not print filename).
The output format for an NFSv4 file ACL, e.g., is:
# file: /somedir A::OWNER@:rwatTnNcCy A::alice@nfsdomain.org:rxtncy A::bob@nfsdomain.org:rwadtTnNcCy A:g:GROUP@:rtncy D:g:GROUP@:waxTC A::EVERYONE@:rtncy D::EVERYONE@:waxTC
In the example output above, the user `alice@nfsdomain.org' has the equivalent of "read" and "execute" permissions, `bob@nfsdomain.org' has "read" and "write", and both `GROUP@' and `EVERYONE@' have "read".
The ACL listings of multiple files are separated by blank lines.
Refer to the nfs4_acl(5) manpage for detailed information about NFSv4 ACL terminology and syntax.
