Hello all, I understand there is much information on permissions but i was wondering about a particular case..
made a shared dir
need multiple groups shared folders in this dir

So how do i set the appropriate standard and special file system permissions so that anything created or placed in the folders will be owned by the group, and users cannot delete other peoples work, only their own ?

Also id like to add the appropriate folders to each user’s PATH variable when they log in
and set each user’s prompt in the Software group to display the username, and the current directory each time they log in

Thanks in advance

In order to protect public data from others, simply add sticky bit on the directory, so only root, owner of the directory or owner of the file will be able to delete the content of the directory. To set it:
~$ chmod a+t /path/to/directory
You can also consider adding the SGID permission on each directory according to the group it belongs, so only those users will be able to alter/modify the data inside it, who are member of the group.
~$ chmod g+xs /path/to/directory
In order to set prompt, simply append following line in every user's ~/.bashrc or ~/.profile file:
PS1="\u{\w}\!$ "
