Re: Create a bash-script that runs C-files in ROOT

hi,

it seems to me like all of this could be trivially done and with minimal (if any) hassle in pyroot.

$ cat fooscript.C
void dostuff(const char* fname)
{
  // do stuff
}

$ cat doit.py
import glob
import ROOT
ROOT.gROOT.SetBatch(True)
ROOT.gROOT.LoadMacro("fooscript.C")

fnames = glob.glob("folder?/*.root")

for fname in fnames:

   ROOT.dostuff(fname)
# EOF # the obvious advantage being that you only load ROOT once. the obvious disadvantage being that you (may) retain state between the various calls to dostuff.

hth,
sebastien.
