Re: Making /bin/sh == bash. Has the time come?

Wow. I never expected that bash would actually be faster.

I would appreciate getting a few more benchmarks for other packages.
If this holds out then moving to bash is a no-brainer.

FWIW, there has been a concerted effort in libtool-2.0 to replace fork/exec'ed subprocesses with builtins whenever available (e.g. fork/exec on ash, but if SHELL=bash/ksh/..., use some builtin construct). This is bound to help with respect to configury-type "benchmarks" as projects upgrade their libtools.


Thus, things are only going to get better, in the ash-vs-bash race.

With respect to alternatives, I was thinking about packaging that up for cygwin anyway, because the new family of automake packages could use it, instead of the hacked-together pseudo-alternative scheme it's using now. I haven't had a chance to look into it yet, tho.
