What Others Think

Should be rename 's/txt$/md/i' *.txt instead of rename 's/.txt/.md/i' * to make sure it doesn't accidentally match ".txt" somewhere in the middle of a filename.

@mobilediesel Yes, you are right. I haven't thought of it. Thanks big for the amendment!

Also, if you have s/.txt/.md/i, you want to escape the periods; they're metachars in REs. Otherwise it'll replace "asdftxt" with "asd.md"
