Re: Could bash do what make does?

You have gone to some trouble with your answer Eduardo, and thanks for that but really you are arguing against a proposition that I have not put and I do not want other readers to be mislead. I am asking about shell scripting of software builds, something that is perfectly possible to do and once must have been the common way. I do not want to see make reimplemented inside bash. Sure, that sounds silly. I think some other contributors have understood my question even without the clarification that has been made. I personally don't mind talking about the related but distinct things that you have raised but I think it would be a wrong to do that in this forum.

"build market"? What are you talking about? make was created with the
sole purpose of build automation. The shell was created to provide a
"human interface" to computer operators. These are very specific and
different purposes. Are you going to start asking next to re-implement
vi inside bash? to re-implement a mail user agent? a C compiler? Where
do you draw the line? Read:

I doubt anyone is willing to go through the effort to re-implement all
the features that make provides, just because one guy thinks "it's
obsolete" -- it's not, by the way. make is very alive. Also, it is
part of the POSIX international standard. so any operating system that
claims to be compatible with UNIX must provide it, see [1] and [2] and
[3].

Also remember that nothing makes a stronger argument than patches. If
you want to see this feature implemented, I suggest that you start
looking into the features make provides, and send patches to add said
functionality to bash.
