Lapis Lazuli | Level 10

Hi experts,


I'm using unix environment.


Is there a shell command to list all groups or users that have access to a specific location or file ?


ls -l does not work for me, because i need all users that can read from that directory.


Thanks in advance

ls -l is the primary tool for this. It shows you the permissions for the owner, the group and all others.

On top of that, you may have an access control list (ACL) defined. On AIX, one uses aclget to retrieve that information.

This is all you need for determining access to a directory/file.


To display members of a group, use the lsgroup command.

I need to show groups per folder/directory.


For example:


staff | /prod/crm

controlm | /prod/bi

If "others" have read permission, everybody has access. If not, but the group has read permission, then all members of this group have access. If neither, only the owner has access. That's it. Unless you have defined ACL's.
