I am very new to scripting....i want to write a script that asks me to enter a variable and the plugs that into a command

For example I run test.sh
And it asks me for a file name
I enter 'file' and it renames 'file' to 'file1'
How can I do this?
Anyone know of any good sites to get scripting tutorials?
thanks
Dan Lansing
