Ubuntu – How to preview HTML documents from the command line

You cannot do this with Nautilus or Compiz, no. I don't know what exactly the screenlets you are talking about are, but the general answer is no. File managers and the window manager, do not use a webkit view to draw the background and icons. This works in Windows, because the file manager and web browser, are the same thing. In Ubuntu, they aren't.

Thanks for all the answers, everyone. With your help I was able to compile a list of commands that can extract the page count from almost all relevant office documents:

DOCX/PPTX

unzip -p 'sample.docx' docProps/app.xml | grep -oP '(?<=\<Pages\>).*(?=\</Pages\>)'

unzip -p 'sample.pptx' docProps/app.xml | grep -oP '(?<=\<Slides\>).*(?=\</Slides\>)'

Note: unzip can be installed with sudo apt-get install unzip.

DOC/PPT

wvSummary sample.doc | grep -oP '(?<=of Pages = )[ A-Za-z0-9]*'

wvSummary sample.ppt | grep -oP '(?<=of Slides = )[ A-Za-z0-9]*'

Note: wvSummary (case-sensitive!) is part of the wv package. Install it with sudo apt-get install wv.

ODT

unzip -p sample.odt meta.xml | grep -oP '(?<=page-count=")[ A-Za-z0-9]*'

PDF

pdfinfo sample.pdf | grep -oP '(?<=Pages:          )[ A-Za-z0-9]*'

Note: pdfinfo is part of poppler-utils and should come preinstalled on Ubuntu.

DJVU

djvused -e "n" sample.djvu

Note: djvused is part of the djvulibre-bin package and may be installed with sudo apt-get install djvulibre-bin.
