Does Cygwin or POSIX have a tool to test whether a file is owned by a

Win32, like Linux and POSIX, has the concept that files have an owner,

and a group (ref:https://learn.microsoft.com/en-us/windows/win32/api/ aclapi/nf-aclapi-getsecurityinfo).

How can I test whether a file is owned by a given group name, or not?
/usr/bin/test -g and -G do not help because they only look and gid,
egid. But I want to pass the group's name as an argument.

Sebi

Group name:
stat -c %G <file>

Group ID:
stat -c %g <file>

Sorry, so:

[ "$(stat -c %G myfile)" = mygroup ]

will return true (i.e. $? zero) if myfile is owned by mygroup.
