Multiple owner and groups to file and directory

[Manoj1]

Hi All,

How do we give multiple owners or groups permissions to a file or directory ?

Thanks,
Manoj

man acl

This gives you lots of additional controls for files and directories.

you can achieve this via ACL.

[nijokj]

you can set this by using chacl command.


The general form for the chacl command is as follows:


$ chacl 'user.group operator mode' file_name


where: user and group indicate the user's login name and group; a percent sign (%) means all users or groups. The operator indicates adding (+) or denying (-) permissions and an equals sign (=) means "this permission exactly." The mode indicates the permissions allowed: read (r), write (w), and execute/search (x). An operator immediately precedes the mode (for example, +rw adds read and write permissions; -rw denies read and write permissions).


$ chacl 'carolyn.users=rw' myfile


$ ll myfile


-rw-r-----+ 1 nora users 236 Mar 8 14:23 myfile


$ lsacl myfile


(carolyn,users,rw-) (nora.%,rwx) (%.users,r--)(%.%,---) myfile
