The NSS Rights Utility (rights) for Linux allows you to specify trustee rights for directories and files in the NSS file system. This utility does not provide support for trustees on Linux file systems. It is also not meant to be used to set trustees for NSS volumes on NetWare. The trustee information is saved in the file and directory metadata in the NSS volume and works seamlessly with NetWare if the volume is moved to a NetWare server.

The user name is the Fully Distinguished Name of an eDirectory object, including the tree name. Use the username.context.treename format, such as
joe.engineer.acme_tree
If you use special characters in a user name, you must escape those special characters in the command line.
For example, the $ (dollar sign) is a special character reserved to the shell and must be escaped. For the bash shell, the command could be written in one of two ways on the command line:
rights -f /media/nss/DATA/stuff -r none \$j\$o\$e.engineer.acme_tree
rights -f /media/nss/DATA/stuff -r none '$j$o$e.engineer.acme_tree'
If you are using another shell, the special characters might need a different escape technique. In this case, please refer to the shell documentation for this information.
The mask is a string of characters, with each character representing certain rights. The following table lists the rights, the letter to use for each right, and what the right is used for.
