Copy one file from grid

One often needs to copy a small data file to local area from grid to debug code before submitting large crab jobs. One way to do this is using web-based "filemover" tool:

https://cmsweb.cern.ch/filemover

After trying this a few times turns out that it is very slow. An alternative would be to use LCG utility, as was pointed out in the PhysicsTools hypernews: 
cmsenv
source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh

then

lcg-cp -b -D srmv2 --vo cms "srm location" directory

For example,
lcg-cp -b -D srmv2 --vo cms 
"srm://srm.ciemat.es:8443/srm/managerv2?SFN=/pnfs/ciemat.es/data/cms/store/group/ewk/MinimumBias/Commissioning10-SD_JetMETTau-Jun14thSkim_v1-EWK_HighPtMuSkim-v1/262fa66c8fc0da925698a868d3d7b3dd/EWK_HighPtMuSkim_SD_Mu_15_1_KIJ.root" 
/tmp/hdyoo/EWK_HighPtMuSkim_SD_Mu_15_1_KIJ.root

The "srm location" is different in each T2. So you should know the 
information.
