creating something simular to a dos batch file?

[JesterDev]

How would I go about writing a batch file under linux? Just as an example, say I wanted to copy all the files in a dir to another dir. In dos I would use:

copy *.* c:\somedir

And call it something like copy.bat

I'm looking to create something a bit more complicated, but I'm not sure how to go about this.

"bash scripting"

or something similiar...

cp /usr/dir1/* /usr/dir2/

Thank you. That's exactly what I was looking for. :)
