Anders example:
  bash scriptname.sh
is in openSUSE equivalent to 
  sh scriptname.sh
in instructions on nVidia web site as sh is only symlink to bash.
Calling direct bash is faster, which is here not so important because that is 
only one call, but shows good programmer habit to avoid way around.

Yet another method to run any file as executable script:  
  . filename
Above is pulled out of scripts that booting and setting up the system.
Note that there is at least one blank between, which is different from
  .filename
that has no space between and means hidden file for normal
  ls
command. 

For both methods it is not important that it has executable permissions set, 
or to have extension .sh. 

Example:
It was created file irun with single command
 echo I am running

Executable permissions are not set.
  rajko@linux:~> ll irun
  -rw-r--r-- 1 rajko users 18 2007-02-04 19:07 irun

Run using sh or bash:
  rajko@linux:~> sh irun
  I am running
  rajko@linux:~> . irun
  I am running
  rajko@linux:~> .      irun
  I am running

While 
  rajko@linux:~> ./irun
  bash: ./irun: Permission denied
fails because file has no executable permissions set.
