Where did ash (a stripped down bash?) come in ?
As I understand it, it all goes back to the big bang...
I don't understand the question. Cygwin has for a long time used ash
as it's /bin/sh. Ash is a POSIX compliant shell and is much
lighter-weight than BASH. For purposes such as interpreting commands
issuing from makefiles, it's faster start-up time makes it a better
choice.
You script assumed BASH--that is, it used BASH-specific features. Thus
it should explicitly invoke bash in its #! line. The fact that most
Linuxes use BASH as their /bin/sh probably falsely led you to believe
that BASH was _the_ shell in POSIX-compliant systems. That's not true.
In fact, for a long time, even /bin/bash was a version 1.2 BASH, and
that was a far cry from what we now know as BASH.
I see the light
