Git commands require a Posix-style shell (with support for $() among

you’re talking about.  Still, portability is something to worry
about...

    echo ()

    perl -le'print "Done!"'

    xx.sh[3]: The operation is not allowed in a restricted shell.:
echo is a shell builtin.
    1
    Klaar

That’s weird.  Where did “restricted shell” come into it?

Thanks for the example,
