ok, here is the full java code: class ReduceFile{ public static void main(String[] args) throws Exception{ BufferedReader reader = new BufferedReader(new FileReader(new File(args[0]))); BufferedWriter writer = new BufferedWriter(new FileWriter(new File(args[1]))); int length = Integer.parseInt(args[2]); String s = reader.readLine(); while(s!=null){ writer.write(s.substring(length,s.length())+"\n"); s = reader.readLine(); } reader.close(); writer.close(); } } Then execute with : "java ReduceFile fileIn fileOut n" Cannot be simpler... (though i agree that java is quite a verbose language compared to perl) Michiel Ward Blondé wrote:

Thanks for all the answers. I tried this 'sed' method of Kenny but it reduces my file to the characterless file. I 'll try something else.

apparently, you also have to escape the {} in tcsh .. so the sed solution becomes:
sed "s/^.\{,2\}\(.*\)//" infile > outfile
