Some LibreOffice tricks

Batch convert LibreOffice files to PDF

sudo libreoffice --headless --convert-to pdf *.docx

Just does what it says on the tin .. easy as. Note: sudo is needed - thanks Jay http://listarchives.libreoffice.org/global/users/msg28788.html and https://bugs.freedesktop.org/show_bug.cgi?id=37531

LibreOffice won't start (unless --norestore is used)

I often shut-down my laptop without checking for working documents / emails in draft. Things are so reliable in general that I can start up and continue (generally also the docs / emails were no so important that I could just walk away from unfinished). Lately I've had had the issue that I just couldn't start LibreOffice .. I found --norestore but needed it every time.

Check for restore items in the following file and just delete them
