You are probably in the "users" group. Running either the "groups" or "id" command will say for sure. > $ ls > test.txt > $ rm test.txt > > ***After creating a special "Share" user*** > > $ cd /home/Share > $ ls -la > total 4 > drwxrwxr-x 2 Share Share 512 Nov 17 21:04 . > drwxr-xr-x 5 root wheel 512 Nov 17 21:04 .. > $ cat > test.txt > cannot create test.txt: Permission denied > $ grep Share /etc/group > Share:*:1003:james,backup > $ If you are currently either the "james" or "backup" user, and added the Share group membership on another tty, then you may need to log out and back in for the system to assign your new group membership to your session.
