How set default emacs in ksh

[j773303]

As title.
I try to use "ksh -o emacs".
But I can not use keyboard UP and DOWN button to find the command history. Does anybody can tell me how to let ksh can search command by UP and DOWN button.
Thanks.

Yes, I know it can be use "ksh -o vi"
But the the customer has the problem about "ksh -o emacs"? I also can not use "UP" "DOWN" to find previous command by emacs in hpux. Do anyone know how to fix this problem? Thanks again.

Hi,

Apart from issuing "ksh -o emacs" have you enabled history feature in your profile.

Please make sure these variables are defined in your .profile file in home directory.. "HISTFILE" and "HISTSIZE".

#echo $HISTFILE
#echo $HISTSIZE

If not defined please consider defining one as follows in your .profile

HISTFILE=~/.sh_history
HISTSIZE=200
export HISTFILE
export HISTSIZE

Hi,
I try to
HISTFILE=~/.sh_history
HISTSIZE=200
export HISTFILE
export HISTSIZE

But ksh -o emacs, still can't use "UP" and "DOWN" button to find the previous command.

Any comments please advise, thanks again

Hi,

I think you'll have to use
^p (Ctrl p, previous) for UP and
^n (Ctrl n, next) for DOWN
navigation - just the same keys as in emacs.
