The permission bits are implemented as normal Window's DACLs (Discretionary Access List). +s is implemented magically with the NULL SID. You can view it from Explorer or with icacls. Try checking the return code (echo $?) from chmod. Also try changing perms from Explorer. You might not be able to set the NULL SID for some reason. It works for me: $ ls -ld z drwxrwsr-x+ 1 wagnerc Users 0 Nov 24 2020 z $ getfacl z # file: z # owner: wagnerc # group: Users # flags: -s- user::rwx group::r-x group:Administrators:rwx group:Users:rwx mask::rwx other::r-x default:user::rwx default:user:wagnerc:rwx default:group::r-x default:group:Administrators:rwx default:group:Users:rwx default:mask::rwx default:other::r-x $ icacls z z NULL SID:(DENY)(Rc,S,WD,REA,WEA,X,DC) APPLEJACK\wagnerc:(F) BUILTIN\Users:(RX) BUILTIN\Administrators:(RX,W,DC) BUILTIN\Users:(RX,W,DC) Everyone:(RX) NULL SID:(OI)(CI)(IO)(DENY)(Rc,S,WD,REA,WEA,X,DC) CREATOR OWNER:(OI)(CI)(IO)(F) APPLEJACK\wagnerc:(OI)(CI)(IO)(RX,W,DC) BUILTIN\Users:(OI)(CI)(IO)(RX) BUILTIN\Administrators:(OI)(CI)(IO)(RX,W,DC) BUILTIN\Users:(OI)(CI)(IO)(RX,W,DC) Everyone:(OI)(CI)(IO)(RX) Successfully processed 1 files; Failed processing 0 files $ uname -a CYGWIN_NT-6.1 applejack 3.1.0(0.340/5/3) 2019-11-19 13:58 x86_64 Cygwin Thanks. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
