You're preaching to the converted; see https://lists.debian.org/debian-user/2023/01/msg00562.html two posts back. My comment was with respect to your point 2, which was about non-bracketed paste, and which was snipped off the top of your post. BTW are you implying that dash does bracketed paste? I didn't know that. > For instance, in zsh: > > cventin:~> foo1 > foo2 > foo3 > > If I type [Enter], I get: > > zsh: command not found: foo1 > zsh: command not found: foo2 > zsh: command not found: foo3 > cventin:~[127]> > > But instead of [Enter], if I type Ctrl-C, I just get: > > cventin:~[1!]> > > Nothing has been executed.

Quite clever, that. You quote my comment after some anecdote of yours that gives it the opposite context, so you can then disgree with it. BTW I don't know anything about nooks and zsh. As I said at the end of my previous post, I'm not really interested in > > testing the gamut of releases, terminals and shells. But if you are, then it might be worth your posting a summary of your findings in the form of a table that others could understand, rather than in a back and forth of over-snipped posts. Cheers, David.
