Hi list, i would like to define global variables for all the user of a Debian system, for example the following: CERN=/usr/local/cernlib CERN_LEVEL=2005 CERN_ROOT=/usr/local/cernlib/2005 PATH=/usr/local/cernlib/2005/bin LDPATH=/usr/local/cernlib/lib Where do i have to put them? I was thinking of ld.so.conf and then run ldconfig. Is it the right choice? What about /etc/environment ? Regards, MC
