Default ksh: wrap lines?

Is it possible to configure ksh to wrap lines which exceed the terminal width?
I couldn't find anything appropriate in ksh/stty/getty man pages...

I think some wrap occur through your terminal.
from man xterm
Quote:
-aw This option indicates that auto-wraparound should be allowed.
This allows the cursor to automatically wrap to the beginning
of the next line when it is at the rightmost position of a line
and text is output.
Additionally, you can set line length with format
in man vim

Thanks.

I'm away of 'set textwidth=n' in vim but I want line wrapping the the shell.
'xterm -aw' doesn't fix that.
Running bash in the same xterm *does* line wrapping. So it seems this behavior is causes by ksh.

Any further ideas?

I think you want to do a set -o multiline.

Excerpt from man ksh:

multiline:

The built-in editors will use multiple lines on the screen for lines that are longer than the width of the screen.

BTW, if using the standard vi editor in OpenBSD, not vim, you will get line wrapping at 72 characters with the following in a ~/.exrc :>

set wrapmargin=8
set autoindent
set shiftwidth=4

The multiline option sounds very interesting, but I don't find it in ksh(1). Is it perhaps for a variant version of ksh that has to be installed as a package?

Yes if I recall it is 5.12; so for OpenBSD ksh console, I think the LINES perimeter needs to be set.

If in X, one could do something like this in a ~/.profile:

alias resize='eval `/usr/bin/X11/resize`'

or

eval $(resize) -- the resize utility has two options:> [-u] [-s [row col]

Set the ksh alias; after resizing a window in X, but before running an application, type:

resize

that should do it.

'resize' doesn't work for me. It sets the COLUMNS and LINES variable but the ksh still doesn't wrap long lines.
It hard to imagine all ksh users are satisfied with the non-wrapping behavior...

Just to clarify, you mean wrapping your input lines?

edit: or I guess output from commands such as ps -aux

Yes.
Because I'd like to see the whole command before hitting Return.

Alright! It can be done by disabling emacs editing mode.

Code:
$ set +o emacs
Its a scary world without it though, if you are used to it

Thank you! I always knew emacs is the root of all evil.

Strangely enough 'set -o vi' behaves like emacs with respect to line wrapping.

Coming back to thomasw's suggestion of

% set -o multiline

this works with ksh93 (verified on Linux). That isn't the OpenBSD system ksh, but it's available as a package, so might be worth a try if you're willing to install another shell.
