[Sbcl-devel] run-program "/bin/sh"

Hi all,

Can anyone explain how I can run a shell subprocess within sbcl repl?

I tried all the combination of :input :output and :pty but it doesn't
seem to work. I don't know enough of sbcl's internal to figure out
what's missing.

Attached are some sessions with sbcl and acl80 (which can run sh
without any problem) under linux 2.6.

Thanks in advance,
fungsin.
