• A tutorial for HTCondor can be found here: https://batchdocs.web.cern.ch/tutorial/introduction.html
• Sometimes you may get an error and can't submit jobs to HTCondor. Sometimes changing the scheduler can solve this issue. Use this command in LXPLUS to change the scheduler (here it would be changed to bigbird15):

  export _condor_SCHEDD_HOST="bigbird15.cern.ch" ; export _condor_CREDD_HOST="bigbird15.cern.ch"
