No!! On both systems sh is _NOT_ bash. sh is ash which was written
specifically for Linux to be a lightweight shell in order to increase
processing speed.
That depens on the Linux distribution, I believe. On my home system,
sh is bash. And ash is older than Linux, methinks.
Is ash supposed to be a full implementation os the POSIX shell? If
not, you'll always run into scripts that are hash-banged with
#!/bin/sh but contain constructs ash won't understand.
Not a flame - I understand that there may be excellent reasons to
avoid the full weight of bash in an emulated environment like Cygwin.
