Part V: Under Mac OS X's Hood > Pattern Matching

Chapter 20. Pattern Matching

A number of Unix text-processing utilities let you search for, and in some cases change, text patterns rather than fixed strings. These utilities include the editing programs vi and Emacs, programming languages like Perl and Python, and the commands grep and egrep. Text patterns (formally called regular expressions) contain normal characters mixed with special characters (called metacharacters).

For more information on regular expressions, see Mastering Regular Expressions (O'Reilly & Associates, Inc.).
