Question : Scripting newbie question

Hi Friends,

i need to know some things about bash scripting

First how can i make my attached script shorter?

Second how to make my script executable from whole system ...meaning if i have made script in /tmp/scripts dir then rather then using /tmp/scripts/select1.sh i simple type ./select1.sh or type selcet.sh anywhere in the system it shold run.

Thanks For being with me
