Hello billy,
Nobody using Linux is stupid, not you, not me, but a
lot like me are very unknowledgeable and new to the
OS.
I checked a few of the script file I wanted to run and
they were all executable(3-x's). Btw, these are all
Kubuntu script files and I did discover that there are
both .sh and bash script files. Was only aware of the
.sh kind til now so maybe I improved my knowlege just
a bit. Since these are all Kubuntu executable conf and
setup files, I would expect them to have the proper
perms and wouldn't have thought to check without your
input. Thanks.
