Finding repeating words in a document

Q

How to find repeating words in a text document with a regular expression?

An example text document is listed below:After narrowly escaping a sensitive decapitation, Bond Bond is shot with a tranquilizer gun. He wakes up up on a plane to a woman standing over him, who introduces herself: "My name is Pussy Galore."

The regular expression to find repeating words in a text document can be written as: \b(\w+)\s+(\g1)\b Note that:

\b(\w+)      - identifies a word
\s+(\g1)\b   - the same word repeated again using backreference
