The difference between JavaScript's `exec` and `match` methods is subtle but important, and I always forget...
var str = "The quick brown fox jumped over the box like an ox with a sox in its mouth";
str.match(/\w(ox)/g); // ["fox", "box", "sox"]
// match (when used with a 'g' flag) returns an Array with all matches found
// if you don't use the 'g' flag then it acts the same as the 'exec' method.
str.match(/\w(ox)/); // ["fox", "ox"]
/\w(ox)/.exec(str); // ["fox", "ox"]

magic of sed -- find and replace "text" in a string or a file
FILE SPACING:
# double space a file
sed G
# double space a file which already has blank lines in it. Output file
# should contain no more than one blank line between lines of text.
sed '/^$/d;G'
