Tab complete in VI mode KSH 'vi-tabcomplete' gives bad options

Question

When I try stuff like in my .profile: set -o vi-tabcomplete

I get .profile[292]: vi-tabcomplete: bad option(s)

Anyone know of a workaround?

Answer 1

It depends which flavour of ksh you have.

Older pre-ksh-93 shells support 'double-escape' auto complete - so you hit escape twice instead of tab once.

ksh-93 uses set -o viraw to enable tab completion.

Public-domain ksh, pdksh which you may be able to obtain and use if your environment permits, is the one that supports the set -o vi-tabcomplete syntax. It also supports set -o vi-esccomplete for compatibility with older ksh variants.

Answer 2

In Fedora 11's ksh, you get tab completion after just set -o vi
