WSH is a window managing command language interpreter (shell) for the UNIX operating system. This interface increases a user's power to communicate with UNIX by providing a process management environment based on an integrated virtual terminal‐shell design. Unlike conventional shells, WSH affords its user the ability to monitor and communicate with multiple processes within a single display context. Windows represent virtual terminals in the WSH design, and as such are device‐independent abstractions of real terminals. Since the design of the virtual terminal environment is based on UNIX's TERMCAP terminal database facility, WSH is portable across all versions of UNM supporting this feature. WSH requires neither alteration of existing UNIX facilities nor special display devices. The current implementation runs on a Digital VAX 11/780 under Berkeley UNIX 4.1 environment.
