Run *. run on Linux(extention-run)

I usually use Ubutu.
As you move through Ubutu, you may need to install a file, but when you download and install it, let's learn how to install a file with the *. run extension.
You can do that by shoveling a lot and then chmod.
1.

# chmod a+x install.run
# sudo ./install.run

2.

# chmod 755 install_test.run
# sudo ./install_test.run 

The third method turns on the ubuntu explorer.
Right-click and click Property -- > Permission's Excute :
Check it and it will run immediately.
