Changing default shell on PogoPro

My PogoPro is using

sh

as it's default shell (on the stock Pogo OS). It's not saving a command history, but I'd like it to. I was able to see that

ash

and

hush

shells are also available. When I switch into one, it saves commands only for that SSH session. Is there a way to set

ash

or

hush

to the default, or better yet install and set bash as the default?

Thanks for any advice.

The last column in the passwd file is the default user shell. So if you want to change the default shell for the root user you would modify the entry for root in the passwd file so that the last column would be /bin/ash or /bin/hush. You'll want to ensure that the shell binary is in the /bin directory. If it is in a different directory just modify the path appropriately.

Thanks Ray. I found the file and was able to switch the default editor to ash, however I'm still unable to cycle through my previous commands using the up arrow in my mac terminal Looking at this page https://en.wikipedia.org/wiki/Comparison_of_command_shells it seems like ash should support command history, but maybe that's not the same thing as being able to toggle through previous commands??
