It is possible to use from bash something like this: root -b -q -l
`macro.C(arg0,"'$arg1_1'","'$arg1_2'","'$arg2_1'","'$arg2_2'")' 1>$output_f 2>$error_f
where arg0 is just real argument and the rest (everything with $) are some variables defined before the root call (you could want to have some loops over some files and pass those files as an argument to root macro) It helped me to automatically create hundreds of qsub jobs :D each with their file argument :D Received on Sat Mar 10 2007 - 16:10:58 CET
