Subject: Bug#730:  !-shell from less in same process group?

Ian,

I see this as a non-bug, so I'm closing it.

As I understand it, you're questioning that a SIGINT
goes to the child process.  I see this as a designer's
choice issue with arguments to be made either way.  If
you have an argument to make on this issue, I invite
you to make it directly to the designers of less
(and/or bash).

Subject: !-shell from less in same process group ?

Package: less
Version: 278-1

Try the following:

>From within an X session, run `less' on a file.  Type at it,
  !xterm&

You'll see the xterm appear, and less will say `done' or some such.

When you get back to the main `less' display, press ^C.  The xterm
disappears.

I conjecture that less is failing to put its subshell into a different
process group (which IMO it should), so that the xterm inherits less's
process group.  This may also be a bash bug, I suppose.

Ian.
