Introducing PowerGREP PowerGREP is a versatile and powerful text processing and search tool based on regular expressions. A regular expression is a pattern that describes the form of a piece of text. E.g. a regular expression could match a date or an email address. Any date or any email address that is, without specifying actual dates or actual email addresses. Your search patterns can be as specific or as general as you want. This makes PowerGREP much more flexible than a general search tool that only finds words and phrases (PowerGREP can do that too). The tasks you can perform with PowerGREP broadly fit into three categories: - Find files and information. Search using one or more regular expressions and/or words and phrases. PowerGREP will display file names, search matches and context, as you like. You can restrict the search to particular folders, files of certain types and even parts of files. E.g. you could search through the headings in the HTML files in the folder containing your web site's source files.
- Edit and convert text and data files. In addition to searching for text patterns, you can use regular expressions to substitute one pattern with another. E.g. you can search for dates in U.S. mm/dd/yy format and substitute them with the same dates in international yyyy/mm/dd format.
- Extract data and collect statistics. Extract useful information by searching through raw data files and save search matches, or regular expression substitution patterns into one or more new files. Group identical matches and count them to gather statistics from various kinds of log files.
