How do we know, which group is allowed to access the particular directory?

how do we know, what is the group of a particular file/directory?

Code: Select all

groups username - groups the current user belong to 
chgrp  - to change his group

Also check out getacl and setacl

usally you use

Code: Select all

cp -p - preserve permissions

How do we know, which group is allowed to access the particular directory?

1. lsuser <user>

2. Based upon the file permission mask for the directory and the ownership of the directory. You must also take into considernation what groups a user is a member.

1) I used

Code: Select all

id <username>

command and i get only one group, but when i use

Code: Select all

groups <username>

. I get three groups the same user belongs to.

Why is that?

2) When I cd to /etc/group. I find only two groups out of three (which appeared using groups <username>

3) Out of the two groups found in /etc/group.
a) one of the groups does not have the <username> in the list of members.
a) the other group has root in the members list.

Can you explain me this?

-Thanks

Why not just have a friendly chat with a System Admin? Or one of your coworkers there that speaks UNIX?

The answer is in two parts - the operating system permissions and the DataStage roles. Other posters have addressed the first; you check the Permissions tab in the Administrator client to view the second.
