On Linux I can do the followin :

---------start ------------------
> history

1 ls
2 cd ..
3 ............etc

> !1

---------end ---------------------
and it executes the ls command with the *!* sign.


on SCO unix I do :

-----------start-----------------
> history

1 ls
2 cd ..

> !1

-----------end--------------------

and it errors : ksh: !1: not found.

Do you know why ?

Yes, I know why.

And if you'd take the trouble to read the ksh man page, you might also
know why.

! is a csh feature (copied into bash, zsh, etc.)
An approximate ksh equivalent of the way you're using it is "fc -s".
See the fc man page.
