A Unix-like grep tool with a lot of sorting methods using regular expressions to fine-tune searches (and a good help file to explain them). There are already two grep tools in the database (http://www.portablefreeware.com/index.php?id=760 and http://www.portablefreeware.com/index.php?id=1240), but they doesn't support Vista and this one seems a bit smoother.
I can't do a full test on the system I have set up, but looks promising. I extracted using Universal Extractor and it appears to save all settings locally (although it doesn't use a relative path name for last directory searched).
(http://www.wingrep.com/download.htm)A fully-functioning evaluation version is available for download. There are no differences between this and the registered version. It does not time-expire.
Seems to be freeware except for a nag at program exit.
