Re: Could bash do what make does?

[Robert Durkacz]

On 29/11/16 Charles Daffern replied to my question about bash and make as
if I was proposing that bash might beneficially reimplement make, but
really I am asking why should not program builds have been scripted with
bash all along and make never invented. So if Charles or someone else could
point out the fallacy in the following simplistic approach, I would be
grateful:
1. Script exhaustively the commands to build a unit of software.
2. Using facilities already in bash or, as appropriate, extensions, have
the commands bypass actual execution when all input files are older than
all output files.
It seems that this gives the same effects and benefits of make but in a
more straightforward way.
