Russ Cox writes he uses bash as his default shell. Does anybody know
the reason? Is this for practicality within the linux environment? Or
has he found rc too limiting?
FWIW, i'm using bash as the interactive shell too, in `konsole' terminal
emulator, because of bash' interactive line edition and command history. 9term
doesn't fit me.
I added command line editing and history to ash under minix a decade
ago, it worked like a charm; the same ash is known as dash in Debian
world, but did not bother to submit a patch.
Whereas, the bash man-page itself explains a lot:
BUGS
It's too big and too slow.
There are some subtle differences between bash and traditional
versions of sh, mostly because of the POSIX specification.
Aliases are confusing in some uses.
Shell built-in commands and functions are not stoppable/restartable.
Compound commands and command sequences of the form `a ; b ; c' are
not handled gracefully when process suspension is attempted. When
a process is stopped, the shell immediately executes the next
command in the sequence. It suffices to place the sequence of
commands between parentheses to force it into a sub-shell, which
may be stopped as a unit.
Array variables may not (yet) be exported.
There may be only one active co-process at a time.

all scripting -- both standalone and in mkfiles -- goes in rc, thou.
It's strange that though ArchLinux uses bash as a system shell :P
