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).

“There are no small number of people in this world who, solitary by nature,
always try to go back into their shell like a hermit crab or a snail.”
