I was so sure of myself, I thought I knew about permissions. Until someone asked me this.
Having these users:
User Group
---- -----
juan juan
pedro pedro
maria maria
jose jose
miguel miguel
eric eric
lola lola
paola paola
This directory: /opt/privado
with Owner = juan:juan
Permissions:
juan 111
pedro 110
maria and jose 101
miguel and eric 100
lola 000
There are no common permissions for creating a group myGroup
and assigning, for example, 110 because I have different permissions for a different group of users. How can this be done on Unix? Really the issue is for Linux, but maybe it is the same solution.
