2. To list a specific directory (e.g. bottom list all /store/user/ directory and all users):
   • gfal-ls -l srm://cit-se.ultralight.org:8443/srm/v2/server?SFN=/mnt/hadoop/store/user/
3. To remove a specific file from T2_US_Caltech:
   • gfal-rm srm://cit-se.ultralight.org:8443/srm/v2/server?SFN=/mnt/hadoop/store/user/jbalcas/my_file/from_my_analysis/file_name.root
4. You can also use rm -r (Remove everything recursively (Be careful and double check full path what you delete))
   • gfal-rm -r srm://cit-se.ultralight.org:8443/srm/v2/server?SFN=/mnt/hadoop/store/user/jbalcas/my_file/
5. To copy file from T2_US_Caltech to your working directory:
