I just posted version 1.0 of zsh to alt.sources. zsh is intended
to be a shell with all the programming power of ksh, but with all the
nice interactive features of tcsh. It isn't yet, but this first
release is a good start, IMHO. Features include:

From ksh:
- all control structures, including select
- shell functions
- process substitution (even w/o /dev/fd)
- parameter substitution, including ${foo-bar},${foo?bar},${foo%%bar}, etc.
- $(...) and `...` command substitution
- regexp filename generation (globbing)
- tilde expansion
- coprocesses
- job control
- cd -, cd old new
- fc, fc -e -
- aliases
- let, read

From tcsh:
- repeat (with a more ksh-like syntax)
- ! history substitution and : modifiers
- termcap support
- PROMPT with %x sequences
- login/logout monitoring
- chcwd, precmd, periodic
- pushd/popd
- sched
- = substitution for directory stack entries
- brace expansion
- noclobber, notify, ignoreeof, autolist, correct,
dextract, nobeep, printexitvalue, pushdtohome, pushdsilent, etc.

From bash:
- $[...] arithmetic substitution
- the readline command line editor

Other stuff:
- "echo =ls" is the same as "echo `which ls`"
- recursive directory search in filename generation (for example,
"ls ..../*.c" lists all .c files in the hierarchy)
- aliases can optionally be expanded anywhere on the command line

And Dinsdale said, "You've been a naughty boy, Clement," and splits me nostrils
open, and saws me leg off, and pulls me liver out. And I said, "My name's not
Clement." And then he loses his temper. And he nails me head to the floor.
