Determine which number out of a list is being processed at the moment
Note that this works for a shell script that runs a perl script with a parameter (see related tip)
batch_name is the name of the perl script that is being run. This can be abbreviated to whatever will uniquely identify it in grep
param_file is the name of the file that parameters are taken from. This needs to be the full name (e.g. param_file.txt)
ps -ef |grep batch_name |awk '{print "grep -n " $10 " param_file"}'|sh
