A critical assessment of the UNIX system

Gives a critical evaluation of the operating system UNIX. It will interest not only UNIX users but also those who must analyse and evaluate operating system performance in a multiuser and multiprocessor environment. Based on UNIX experience, flaws and faults are shown in: file manipulation, protection and synchronisation mechanisms, input-output handling, communication between processes, handling full screen terminals and UNIX utilities. Extensions and possibilities of evolution towards distributed architectures are examined.Anglai
