Either:
chmod 555 scriptname (gives everyone read/execute permission) [2]

or
chmod +rx scriptname (gives everyone read/execute permission)

chmod u+rx scriptname (gives only the script owner read/execute permission)

Having made the script executable, you may now test it by ./scriptname. [3] If it begins with a "sha-bang" line, invoking the script calls the correct command interpreter to run it.
