I would like to execute a program in a shell that needs a custom path added to LD_LIBRARY_PATH. This happens in my .bashrc by default, so on the regular non-screen shell I'm getting no problems. On a detached screen however, the program will not execute with an error message related to an incomplete LD_LIBRARY_PATH. Indeed, $ env | grep LD_LIBRARY_PATH LD_LIBRARY_PATH=/home/nschloe/Work/FEniCS/lib/:/opt/trilinos/dev/openmpi/1.4.3/gcc/4.6.3/release/shared/lib/:/opt/netcdf/4.2.1.1/lib/:/home/nschloe/Work/FEniCS/lib: $ screen -L -d -m sh -c "env | grep LD_LIBRARY_PATH" $ cat screenlog.0 $ so LD_LIBRARY_PATH doesn't seem to be defined in the detached shell at all. It *does* get set in attached shells though. Any workaround for it? --Nico On Sat, Dec 7, 2013 at 6:23 AM, David T.
