acct

The Solaris 2.x version of acct is compatible with the Application Binary Interface (ABI) and the System V Interface Definition (SVID); the SunOS 4.x version is not. The differences involve turning accounting off and the format of the accounting record. In the Solaris 2.x release, with accounting already on, a call to acct with a given path name turns accounting off. In the SunOS 4.x release in the same situation, the call will switch only to another accounting file, and will not turn accounting off.
