Editing Geant4 Installation (section)

====Unix====
If you wish to make the Geant4 binaries and libraries available via your PATH and library path (LD_LIBRARY_PATH on Linux, DYLD_LIBRARY_PATH on Mac OS X), together with default environment variables for locating datasets, you should source the relevant script in CMAKE_INSTALL_PREFIX/bin

On interactive bourne shells (e.g. bash), do (assuming you are in CMAKE_INSTALL_PREFIX/bin):

 $ . geant4.sh
  
This command can also be used to setup the Geant4 environment in other Bourne shell scripts. You can also supply the full path to the script rather than changing to the directory containing it.

On interactive C shells, do (assuming you are in CMAKE_INSTALL_PREFIX/bin):

 $ source geant4.csh
  
In an interactive session you can also supply the full path to the script rather than changing to the directory containing it. The C shell script cannot be sourced directly inside other shell scripts due to a limitation of the C shell which prevents the script being able to locate itself. If you need to source the C shell script inside another, then you can use the command

 cd CMAKE_INSTALL_PREFIX/bin ; source geant4.csh
  
where you should replace CMAKE_INSTALL_PREFIX/bin with the directory you installed geant4.csh in. You can also use the command

 source CMAKE_INSTALL_PREFIX/bin/geant4.csh CMAKE_INSTALL_PREFIX/bin
  
where as above you should replace CMAKE_INSTALL_PREFIX/bin with the directory where geant4.csh is located.
