Well, since no-one seems to have replied, here is my attempt:

--- cut here ---

#!/usr/bin/env python

import fileinput
import string
import sys

def process(line):
	line=string.join(string.split(line,",")[1:],",")
	sys.stdout.write(line)

for line in fileinput.input(sys.argv[1:], inplace=1, backup='.old'):
	process(line)

--- cut here ---

You can then use this as follows:

	$./remove_first_field.py file1 file2

And this should leave you with a backup of the original file (.old).

Hope that helps,

Kindest regards,
