> grep -R '<search term>' *.pdf That won't work. One reason I don't like PDF is that you can't do grep 'clear text' on it. You have to use a tool such as pdftotext then grep its output. As to desktop search program, none is perfect. Microsoft Desktop Search insists on indexing Outlook mails, even if I turn it off. Google Desktop has no rule order for inclusion/exclusion so to only index c:\mydocs, you have to exclude all other folders at C:. Copernic only allows you to use for free at home. Both Google and Copernic have trouble indexing some files in subfolder with space in filenames. Yong Huang -- //www.freelists.org/webpage/oracle-l
