The PWB shell (also known as the Mashey shell) was an early Unix shell.
Distributed with some versions of Programmer's Workbench UNIX circa 1975-1977, it was a modified (and generally constrained to be upward-compatible) version of the Thompson shell with additional features to increase usability for programming, and was maintained by John Mashey and various others (Dick Haight, Alan Glasser).

Famous quotes containing the word shell:
“I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.”
—Isaac Newton (1642–1727)
