Open source grep utility - winGrep

Last night's tip, discussed AstroGrep, an open source grep utility with some limitations. One of its drawbacks is its inability to export only the results for a search to a text file.

grepWin is another free grep utility, available for download here, from developer Stefan Küng. Like AstroGrep, grepWin is a grep utility with only basic features, which can be used to run regular expression searches in text files and some other types of files but not PDFs. While grepWin will not allow only the regex pattern matches to be exported to a file, it does allow the source files to be edited with find and replace searches. This makes it possible to add delimiters to the source files before and after the regex pattern, so the data can be parsed in Excel later.

Note that you'll need to click Search after having run the Replace operation, so the edited version of the text files will be displayed in the results list in grepWin. You will then be able to save the results by clicking on the small arrow at the bottom right of the screen.

Open source grep utility

AstroGrep is an open source grep utility, that you can use to run regular expression searches on multiple text files. It's a good alternative to an advanced grep utility such as PowerGrep (see the Tip of the Night for August 4, 2018) but it has some limitations.

AstroGrep has a simpler layout than PowerGrep, and may be easier to use for beginners. Simply select the search path to the folder containing the files you want to review, and then enter the search or regular expression search in the 'Search Text' box. [Be sure to select the 'Regular Expressions' check box.] I tested this evening, and confirmed that it can run complex regex searches accurately.

Unfortunately, AstroGrep will not run searches through PDFs.

Another drawback of using AstroGrep is that it apparently will not export search results which only include the searched for pattern results. The user only has the option of exporting the full line of text on which the search result appears.

Outlook StatView

Outlook StatView is another great free utility from Nirsoft. It's available for download here.

Outlook StatView will quickly generate a list of all emails in a selected Outlook profile; their domains; the number of incoming and outgoing messages; the date range of those messages; and several other datapoints.

I test it out successfully tonight.
