From Just Great Software
PowerGREP is a powerful Windows grep tool. Quickly search through large numbers of files on your PC or network, including text and binary files, compressed archives, MS Word documents, Excel spreadsheets, PDF files, OpenOffice files, etc. Find the information you want with powerful text patterns (regular expressions) specifying the form of what you want, instead of literal text. Search and replace with one or many regular expressions to comprehensively maintain web sites, source code, reports, etc. Extract statistics and knowledge from logs files and large data sets.
# What You Can Achieve with PowerGREP
PowerGREP offers you a wealth of features that will come in handy in many situations when you want to find information, update or convert files, or extract useful information and statistics. PowerGREP is a knowledge worker's Swiss army knife.
# Find Files and Information
Quickly search across files, folders and archives on your computer or network. Search for words, phrases or binary data. Or use regular expressions to describe the form of what you're looking for, and let PowerGREP find the actual text. Specify as many search terms as you want. Inspect the context of individual search matches, or group identical matches together.
# Maintain and Convert Files with Search and Replace
Search and replace through heaps of files without opening them first. Preview the replacements without modifying any files. Make complex replacements or conversions with regular expressions. Replace or revert individual search matches at your leisure. Work safely with flexible backup and undo options.
# Extract and Collect Information and Statistics
Gather statistics and extract data from files, archives and logs. Collect search matches into one or more new files. Use regular expressions to describe the form of the text you want to extract, and let PowerGREP collect all or part of the match. Sort matches, and group identical matches and count them, to produce informative statistics.
# PowerGREP's Unique Abilities
PowerGREP has a wide range of capabilities you won't find in any other Windows grep tool. While you will use some of these features only occasionally, they will surely save you a lot of time and tedious manual editing on many occasions.
# Regular Expression Lists
Apply any number of search terms of regular expressions sequentially or concurrently. Complex search and replace operations often require multiple steps. Use PowerGREP to execute as many steps as you want in a single operation. Run the steps concurrently (search matches won't overlap), or sequentially (replacements cascade onto the following steps). Save all steps into a single PowerGREP Action for instant reuse.
Similarly, while searching or collecting data, use a list of search terms or regular expressions to find files matching different criteria, or to extract disparate information from each file.
# Slice and Dice Files Any
Executing an action using the \"list files\" action type and the \"save results into a single file\" target type no longer causes the action to fail with an access violation error after all files were found. The list of files is now saved correctly into the target file.
Actions that search through files in an archive and modified some of the files searched through now correctly update the archive. In previous 4.0.x releases the files that were modified were stored correctly in the archive but the files that were searched without modification were damaged.
Creating a portable installation via the Help menu in PowerGREP now copies over the required file 7z.dll. If you previously created a portable installation via the Help menu, make sure to update it with PowerGREP 4.0.6. PowerGREP needs its own copy of 7z.dll. Other versions of this DLL may not work.
PowerGREP no longer hangs when expanding drives that do not support ReadDirectoryChangesW. That includes drives created by 3rd party utilities such as ExpanDrive as well as shared folders in Parallels. Because PowerGREP cannot monitor these drives for changes the globbing process will be repeated for each search. For local drives and normal Windows network drives PowerGREP can monitor changes, allowing it to cache directory listings and skip the globbing process if no files were changed since the last search.
