Grep is the name of the command-line utility for performing regular expression searches in Unix.

(As an aside, many people use the word “grep” instead of “regular expression” in informal speech. In essence, you’re finding the first name, saving that to replacement pattern 1, finding the last name, saving that to replacement pattern 2, and then writing a replacement that reverses the order and inserts a comma between the two. That enables you to do things like reformat a list of names like Tim Cook into Cook, Tim. For instance, putting parentheses around a portion of your search saves that pattern for use in replacement. You can use regular expressions when replacing text as well. You’re undoubtedly familiar with searching for a string-search this document for “string,” and it would find all instances of the word, along with words that contain those six letters, like “astringent.”įar more interesting are regular expressions-sequences of characters that define search patterns-which let you do things like find all phone numbers in a document, all phone numbers that have the 607 area code, or even just phone numbers that are formatted as (#) #-# as opposed to #/#-#. Plus, BBEdit 13 provides live searching in its Find window, automatically highlighting matches as you enter the search term. This update focuses on the pattern-match searching that has long been BBEdit’s core competency, adding a Pattern Playground for interactively experimenting with regular expressions and a Grep Cheat Sheet that provides quick access to many common regular expressions, complete with brief descriptions. The company has now released BBEdit 13 as a paid upgrade, and despite the app’s 27-year history, Rich Siegel and crew continue to think of new features that keep the powerhouse text editor fresh. I want to extract data from these files, clean them up by deleting extraneous bits of data, or reformat them in some way, and the killer app for such text manipulation has long been Bare Bones Software’s BBEdit. I do a lot of work with textual data files, things like membership lists, race results, and team rosters-the sort of thing you get when exporting from a database or saving a spreadsheet in comma-separated value (CSV) format.
