From the book Mastering Regular Expressions, 3rd Edition:
Finding text is one of the simplest uses of regular expressions—many text editors and word processors allow you to search a document using a regular-expression pattern. Even simpler is the utility egrep.
How do you understand the last sentence? Does it mean that this program makes it even easier to find text?
Answer
It’s not worded very well, but I believe you are correct that it means “egrep makes it even easier to find text than an editor or word processor.”
If I were writing the passage, I might phrase it:
Finding text is one of the simplest uses of regular expressions. Many text editors and word processors allow you to search a document for text using a regular-expression pattern. An even simpler way to find text that matches a pattern is the utility egrep.
