Then, as root/admin, change the group ownership to the other user's group, sudo bashĬhgrp group2 $place/shared & chmod g+s $place/shared Mkdir $place/shared & chown oup3s $place/shared & chmod 770 $place/shared Ĭp $file $place/shared & chgrp $place/shared/$file & chmod 660 $place/shared/$fileīut, suppose you cannot create the new, shared group, and place both users in that group?Ĭreate the directory and give it 770 permissions, mkdir $place/shared & chown oup1 $place/shared & chmod 770 $place/shared addgrp group3Ĭreate a directory in a mutually accessible place, where one user owns, but has group ownership of group3s. Suppose user1 is in group1, and user2 is in group2, and both user1 != user2 and group1 != group2.Ĭreate a shared group, group3s.

Assume you either do not have ssh installed, or cannot do do not want to share keys/secrets.
