You can avoid reading the file twice by piping it into tee:
Code:
tee copy < original | gzip > compressed.gz

This will write the original uncompressed data into copy, while at the same time writing it to stdout where a compressor like gzip can handle it.

If at all possible, avoid storing copy and compressed.gz on the same disk you're reading from, it will increase performance to not have to wait for writes to finish for reads to happen. In an ideal world, you could store copy on a different disk from compressed.gz too, to avoid splitting the disk's speed between different writes.

If you really mean .zip and not just some sort of compressor,
Code:
tee copy < original | zip compressed -

...will create a 'compressed.zip' containing a file named '-'.

smf_security(5) 					Standards, Environments, and Macros					   smf_security(5)

NAME
smf_security - service management facility security behavior DESCRIPTION
The configuration subsystem for the service management facility, smf(5), requires privilege to modify the configuration of a service. Priv- ileges are granted to a user by associating the authorizations described below to the user through user_attr(4) and prof_attr(4). See rbac(5). The following authorization is used to manipulate services and service instances. solaris.smf.modify Authorized to add, delete, or modify services, service instances, or their properties. Property Group Authorizations The smf(5) configuration subsystem associates properties with each service and service instance. Related properties are grouped. Groups may represent an execution method, credential information, application data, or restarter state. The ability to create or modify property groups can cause smf(5) components to perform actions that may require operating system privilege. Accordingly, the framework requires appropriate authorization to manipulate property groups. Each property group has a type corresponding to its purpose. The core property group types are method, dependency, application, and frame- work. Additional property group types can be introduced, provided they conform to the extended naming convention in smf(5). The following basic authorizations, however, apply only to the core property group types: solaris.smf.modify.method Authorized to change values or create, delete, or modify a property group of type method. solaris.smf.modify.dependency Authorized to change values or create, delete, or modify a property group of type dependency. solaris.smf.modify.application Authorized to change values or create, delete, or modify a property group of type application. solaris.smf.modify.framework Authorized to change values or create, delete, or modify a property group of type framework. solaris.smf.modify Authorized to add, delete, or modify services, service instances, or their properties. Property group-specific authorization can be specified by properties contained in the property group. modify_authorization Authorizations allow the addition, deletion, or modification of properties within the property group. value_authorization Authorizations allow changing the values of any property of the property group except modify_authorization. The above authorization properties are only used if they have type astring. If an instance property group does not have one of the proper- ties, but the instance's service has a property group of the same name with the property, its values are used. Service Action Authorization Certain actions on service instances may result in service interruption or deactivation. These actions require an authorization to ensure that any denial of service is a deliberate administrative action. Such actions include a request for execution of the refresh or restart methods, or placement of a service instance in the maintenance or other non-operational state. The following authorization allows such actions to be requested: solaris.smf.manage Authorized to request restart, refresh, or other state modification of any service instance. In addition, the general/action_authorization property can specify additional authorizations that permit service actions to be requested for that service instance. The solaris.smf.manage authorization is required to modify this property. Defined Rights Profiles Two rights profiles are included that offer grouped authorizations for manipulating typical smf(5) operations. Service Management A service manager can manipulate any service in the repository in any way. It corresponds to the solaris.smf.manage and solaris.smf.modify authorizations. The service management profile is the minimum required to use the pkgadd(1M) or pkgrm(1M) commands to add or remove software packages that contain an inventory of services in its service manifest. Service Operator A service operator has the ability to enable or disable any service instance on the system, as well as request that its restart or refresh method be executed. It corresponds to the solaris.smf.manage and solaris.smf.modify.framework authorizations. Sites can define additional rights profiles customized to their needs. Remote Repository Modification Remote repository servers may deny modification attempts due to additional privilege checks. See NOTES. SEE ALSO
auths(1), profiles(1), pkgadd(1M), pkgrm(1M), prof_attr(4), user_attr(4), rbac(5), smf(5) NOTES
