HISTORY
A sh command, the Thompson shell, appeared in Version 1 AT&T UNIX. It
was superseded in Version 7 AT&T UNIX by the Bourne shell, which inher-
ited the name sh.
This version of sh was rewritten in 1989 under the BSD license after the
Bourne shell from AT&T System V Release 4 UNIX.
AUTHORS
This version of sh was originally written by Kenneth Almquist.
