search for: data2graph

Hi, I've just started using R and my question is basic I think. Instead of typing each time a lot of lines I'd like to write a script, which basically takes as input a data file and outputs a graph. Something like: data2graph input.txt I know the commands I need to type but I don't know how to write such a script. Should I use a specific software?
