What version of windows does it run on ?
Grep for Windows works on every version of Windows so long as you have Java 1.5 or newer installed on your machine. Check out our auto-download page, it checks that you have a new enough version of Java before starting the download.
How do I save my searches ?
Firstly, you need to have a registered version to actually save the search info.
When you have registered, you will see "Save Search" option in the File menu of each of your search windows. You don't have to save each and every search (in fact you probably wouldn't want to), but the option is there when you get one setup that you know you are likely to use again.
How do I search many directories at once ?
Select the directory where you want the search to start from then make sure you click the "Include Sub-directories" checkbox before click the GO button.
How do I search all of my HTML files ?
We use UNIX shell and MS-DOS wildcard syntax to match filenames:
*.txt as a filename gets all of your files that are named with a ".txt" extension.
inde*.html as a filename gets all of your files whose names start with "inde" with a ".html" extension.
So... To answer the question... Select the directory where you want the search to start from and enter "*.htm" or "*.html" as the name of the File(s) to search in.
How do I use regular expressions ?
Regular expressions are something best worked up to gradually.
There Are a few good books written about them already, including one from O'Reilly.
There are even some web pages devoted to regular expressions, some results from MSN can be found here
Some easy examples though that satisfy most people's needs:
bob.*AK would match lines in a file with the string bob somewhere on the line with the string AK somewhere further along the line. It doesn't match a line where AK appears before bob unless AK appears again on the line after bob.
private.*get.*File would match lines in a file with the string private somewhere on the line followed somewhere later on the line by the string get followed somewhere later on the line by the string File.
