Can you use irb in place of shells like bash or rc?

Can you use irb in place of shells like bash or rc?
not really, but kinda, yeah.
you can do "system ('any unix command')" from inside irb really
easily, and you could also set up a method which automatically took
any input you gave irb and passed that along to system, but you
wouldn't get tab-completion, you'd have to manually print the strings
you received back - they come back with newline escape sequences
rather than newlines - and I really don't know how you would be able
to get system (or backticks, which do almost exactly the same thing)
to load your .profile or .foo_shrc files.
you can do pretty much anything you want in Unix from within irb, but
actual Unix shells remain the best way to do it. (although I think
there was an actual irb shell written, so I could be wrong.)

Some day, some day, somebody smarter and more ambitious than me will
build that Ruby-native shell with all the joy of Ruby and command
line tools integrated...

Thanks to both of you and I can only hope that somebody comes along soon. I
wish I had the experience and skill to do it my self, but multiple failure
with other big and ambitious projects I took on taught me some humility.

This is one of those questions where consulting with rubyforge.org can
be helpful.

hehe working on that with my limited abilities...
Unfortunately, aside from time problems, I found two stop things:
First, I need something that can replace irb easily, so that you
get all the important functionality of irb and which has
sufficient docu to allow "normal" programmers unterstand
what is going on (understanding how IRB works is possible,
but i found it takes a lot of time, and isnt as fun as
starting from scratch)
Something that is as flexible as irb-in-a-browser too,
but for some reason I didnt find this very easy...
Second, I still have no real way on how to do piping of
objects/data with a ruby shell. (After all we are talking of a
real shell, no? One like in bash where you can apply filters...)
And also... ruby-ncurses would be nice to have, so that we
can get zsh-like "borders" around a prompt (and RPROMPT etc..
etc.. etc..)
But for now its a lot easier to replace all t he simple unix
tools in pure ruby... thats not that difficult, just
quite some work
"but you wouldn't get tab-completion"
Well you can, with Readline.readline and using a proc
object for tab completion. The docu is a little bit weird,
but with a little help i got that to work.

Is there a way to integrate that with irb? A Unix shell with .irbrc
special sauce would be pretty nifty. Although I have to admit I
haven't got the hang of it yet:
! ruby ruby_shell.rb
RubyShell> ls (tab)
svn/ ruby_shell/ ruby_shell.rb
RubyShell> ls ../README
RubyShell> ls -l !$
RubyShell> ls -l ../README
ls: fts_open: No such file or directory

Hi,
I have downloaded Rails-1.2.6.zip manually as my proxy settings are
restricting Ruby to do it automatically.
Now that Rails-1.2.6.zip is with me.. To which directory should I
extract these files to.=20
Thanks in advance

I figured you would already know that, which is why I was confused.
Sorry about that.
I've no idea about bash completion either.Regards,

A group of developers, including the author of rbsh, recently got
together for just such a project.
http://rubyunix.rubyforge.org/
We're still working out the design and putting together everyone's
ideas, but an interactive shell, ability to run UNIX shell scripts,
and other such things are among our goals.

That's extremely nifty. I also like the name: rush. I recommend using
the 2112 cover art for maxiumum effect.

no way, dude. that's like slime, the lisp environment. I don't care

In honor of how Rails and Rolls are both named after drugs, I think
the shell should be named after some hard drug.
Like maybe 'Rocks', which is slang for crack cocaine.
