You need to apply the guid for the group it is a special permission that is set by chmod g+s
so that the groups automatically owns the files then you need to apply the other permissions as stated in the question
if you list you should see for the group rws
retry and you will be fine
Hi,
ok that is fine
i see you gave ownership to the group and full rights to user and group if it works it works
but the files created are not automatically owned by the group
if this is asked in an exam like redhat or lfcs it is always special permissions
take care and happy learning
