[ale] first time shell script

[dino]

I have been doing some reading about shell scripts and have some 
questions.  I am using the BASH shell on Mac's OSX.

Most sample scripts say to change the file to an executable via "chmod 
u+x scriptname"
After doing this i should be able to simply type in "scriptname" and it 
should run.

I cant seem to get this to work, I must enter it like this
"bash scriptname"

is this normal or am I not doing something correct?
