Package: dash
Version: 0.5.4-1
Severity: wishlist
When you do "bash -c foo", where foo is a simple command, it's execed.
It'd be nice if dash had this same optimisation (which should be
rather simpler than it is for bash).
It needn't even be done precisely, i.e. for all cases where it could
be used, as long as it covers the most common case:
sh -c foo
In general I believe that simply searching for the absence of a few
special characters `|&(){}' is a good way of catching cases that can
be optimised, without of course catching all of them.
The other alternative is to study how bash performs the same
optimisation.
If this sounds interesting, I'd be happy to try preparing a patch.
