My guess is this defaults to Bash, but would like to know for sure.
Thanks.
The default shell in BusyBox is ash.
dash
derivative of ash
as per busybox shell source code at web.archive.org/web/20210119235542/https://git.busybox.net/…

busybox ash
was originally based on an ancient (2001) version of dash
(mostly, since historical ash
was not portable and is not maintained), modern dash
is significantly different than busybox ash
(mostly: dash
has removed a lot of features). Slackware also maintains a distant fork of ash
.
It's not bash, is a one small file replacement for many small linux/unix utilities like sh and the files utilities
It's written with minimum size in mind and with embedded systems as target where space is a precious resource.
