Setup the ds50 environment

On ds50.fnal.gov, various DS50 utility scripts are installed in the directory /ds50/app/ds50.
setup_ds50 must be sourced first; it sets the values of several important environment variables, makes the UPS products available, and does the (ups) setup of git:

To establish the basic DS50 working environment:

source /ds50/app/ds50/setup_ds50

We do not recommend adding this to your login scripts. Your home directory on ds50 is shared with fnalu, which DOES NOT have access to /ds50/app/ds50/setup_ds50

working with ups

In general, you will only need to setup a single product (e.g., setup darkart vx_y_z -q some_qualifiers).

To see a list of installed versions of some product, use ups list:

ups list -aK+ geant4
ups list -aK+ geant4 v4_9_6_p01a
"geant4" "v4_9_6_p01a" "Linux64bit+2.6-2.12" "e2:prof" "" 
"geant4" "v4_9_6_p01a" "Linux64bit+2.6-2.12" "debug:e2" "" 
setup geant4 v4_9_6_p01a -q e2:debug

Notice that qualifiers must be specified, but their order may be changed.

To see all products currently setup, use the ups active command:

# ups active
