Run bash script without chmod
Solution 1:
I you chmod +x
the file locally, git will see that as a change to the file, and you can push that change so that anybody else who clones the repo has the executable permissions:
chmod +x script.sh
git add script.sh
git commit -m'make script.sh executable'
git push # if you are on a tracking branch
then is will be executable for everybody
I think that is how the repositories that you downloaded accomplished that.
