chmod question ?
Hi,

I am newbie in unix.
I have folder/file own by groupA, how to make that folder/file can write/read for groupB and read only for groupC, and others groups cannot read/write.
Can you help me?

Thank you.

Try this...

make the directory group ownership as GroupA with read/write rights
make the other access as read only

put this directory inside another directory which has it's group set to GroupC. This has read/write group access. The other access of this is ---, this is the important part, if you are "other" you cannnot read/write or traverse (execute).

Then add all members of GroupA and GroupB to GroupC.

The rights would be as follows...

Code:
rwxrwxr-x fred GroupA /.../myparent/mydirectory
rwxrwx--- fred GroupC /.../myparent

so the path to the contents would be

Code:
/.../myparent/mydirectory/myfile

oh.. so Unix permission cannot have multiple group with different permission.
Folder, for groupA write/read, groupB read only, and other no read/write.

Thank you.

Not unless your implementation of UNIX has some form of ACLs (access control lists).

However the restricting by parent directory should work.

Yes it's work, just little bit complicated to manage if I have hundred folder with different permission set. Because I want to migrate from windows server to Fedora. I will try FDS with ACL like u said. I have to read more about unix Smilie.

Thank you very much.
