Hi folks,

when promoting the copying of files to the local disk in condor jobs I 
forgot to give a recipe how to actually do this painlessly (means not 
figuring out where a file is actually located so you can copy it). I 
installed a script from our simulation production (getinputfiles.pl) 
which can do this for you for files which are in our file catalog (all 
production and simulation output). It's argument is either a filename 
(like HIST_DST_TRKR_HIT_run2pp_new_2024p007-00053018-00016.root) or you 
can give it a list of files like

getinputfiles.pl --filelist mylist.txt

It checks the size of the file and the md5sum to ensure data integrity. 
The script is a bit on the complicated side since it has evolved over 
time to be able to use the various copy mechanisms we had, by default it 
uses cp which is the best choice. I just don't want to throw out the 
others in case we ever need them.

I updated our condor wiki to show how to add this to the condor script:

But you can use this script to copy files interactively (not sure why 
you would need it but sometimes you want a file locally)
