Yup, the gnu project's Born Again Shell ("bash") is an attempt
at bashing all the features of sh together with many of those
from both csh and ksh. It is not subject to any AT&T or BSD license,
nor is it subject to any constraints imposed by segmented architectures,
i.e., it won't run on your PC/XT, period. To wit:
$ size bin/bash
text    data    bss     dec     hex
188416  16384   10992   215792  34af0

If you have a reasonable computer to run it on, and a compiler
that isn't hamstrung by historical necessity for compatibility
with segmented architectures, you can get the source (it's free)
and try running it. As with all GNU-ware, THERE IS ABSOLUTELY NO
WARRANTY, etc., etc. See the file COPYING in the source directory
for details.

What does this have to do with the original thread of discussion?
Oh yeah, I almost forgot. Bash has had csh-style job control bashed
into it, along with csh-style history but with Bourne-shell
control syntax (for f in $x  instead of   foreach f ($x)  etc).
Something for everybody?
