If so, how would I do this? Can grep read text from > within PDFs? I don't think so, because PDF files seem to be binary format. There are two ways. The first is using the "strings" program that can isolate printable strings from binary files. The second - the much better way - is to use "pdftotext" to turn the PDF files into regular ASCII text which is greppable then. You could write a kind of "pdfgrep" tool that acts as a wrapper around pdftotext, grep, and your PDF file collection. In any case, it would surely help if your files have meaningful filenames, so they can easily be identified. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
