I use ksh in Emacs mode under Solaris 9. It annoys me the way ksh
scrolls the input line instead of passing to the next terminal line
when there is not enough room. It only happens in the Emacs mode. In vi
mode the line wraps to the next line.

In bash this feature can be enabled or disabled writing "set
horizontal-scroll-mode On/Off" in .inputrc. Is there a similar setting
for ksh?

Thanks in advance.

If you're looking for a version of ksh with a better command
line user interface, you may want to look at zsh. zsh has a ksh
emulation mode.

Thanks for the tip. I haven't used zsh yet, I'll give it a try.
Although this does not solve my problems since I assume zsh is not
installed by default in Solaris hosts and I cannot intall it in all the
machines I use at work.

I've customized ksh in other ways to fit my needs, such as using
cursors to move through history, thus I still hope changing this
horizontal scroll behaviour.

On Solaris, it's the same as for bash, you get zsh, but it's a
10 year old version, not very useful (should still be better
than ksh though).

You should be able to find precompiled packages of zsh for
Solaris that you can instead on your home directory or in
/var/tmp.

Good luck with ksh...

It annoys you? Why? I suspect that you are not using the
word and sentence cursor motion capabilities to their fullest... ?

Most such design decisions, noting that even ksh(1) devolved
from the earliest days of [more or less] smart terminals (like
the VT100) stem from the fact that character handling at left
and right margins was quite problematic in their implementation.
Ksh(1) probably wanted to avoid the issue, as well as potential
scrolling issues -- no two terminals had the same scrollback buffer
behavior. That's why termcap and terminfo have so many workarounds
for specific terminals.

Have you tried unasserting viraw? ("set +o viraw") (untested).
(I do understand you are using [eg]macs mode, not vi mode).

One may additionally download "ie" at the AT&T download
website available through kornshell.com, which implements
the ksh(1)-like CLE as a standalone "adverbial" executable
that can be used with any tool that takes stdin. It is also
much more configurable.

And how usefull is "zsh"'s ksh emulation mode ? Last time I tested it it
didn't pass even 5% of the ksh93 test suite. It may better be titled a
"ksh-like emulation" since it is FAR away from being compatible to the
korn shell.

Yes, get ksh93 from http://www.kornshell.com/ and use the "multiline"
option, e.g. add "set -o multiline" to ~/.kshrc
The ksh93 version which will be added in Solaris 11 (see
http://www.opensolaris.org/os/projec...3-integration/) will have this
option enabled by default in /etc/ksh.kshrc

zsh ksh emulation is a ksh88 emulation. It also has some
features of ksh93 (and ksh93 borrowed some features from zsh)
but it certainly isn't a ksh93 emulation.
