S.t.a.l.k.e.r. Clear Sky Console Commands

I do not think that there is a binary named libreoffice as one of the other answers suggested. However, there is soffice(.bin) -- the binary that can be used to start LibreOffice from the command line. It is usually located in /usr/lib/libreoffice/program/; and very often, a symlink /usr/bin/soffice points to that location.
