I have the following text file

Eif2ak1.aSep07
Eif2ak1.aSep07
LOC100042862.aSep07-unspliced
NADH5_C.0.aSep07-unspliced
LOC100042862.aSep07-unspliced
NADH5_C.0.aSep07-unspliced

What I want to do is to remove all the text starting from period (.) to the end. But why this command doesn't do it?

sed 's/\.*//g' myfile.txt

What's the right way to do it?
