> the history command is cool but it would be nice to be able to use things
> like:
> * !142 (run the command from the history with index 142)
> * !os (run last command starting with "os")
> =========================
> See http://www.gnu.org/software/bash/manual/html_node/Event-Designators.html
> =========================
> with this patch, we can access history command list with
> ! indext
> ! commandPrefix
> for example, history we get
> 345 osgi/list
> then
> "! 345" or "! os" we get "osgi/list" execute again
> seems we have to add a whitespace between ! and the index number or
> commandPrefix, so the syntax is not exactly same as bash (which no whitespace
> between ! and index number)
