features, notably command input
history, allowing earlier
commands to be recalled and edited (though it was still not as
good as the
VMS equivalent of the time).
Presumably, csh's
C-like
syntax was intended to endear it
to programmers but sadly it lacks some
sh features which are
different syntaxes for every shell construct.
A plethora of different shells followed csh, e.g.
tcsh,
ksh,
bash,
rc, but sh and csh are the only ones which
are provided with most versions of Unix.
