I need help counting the fields and field separators using Nawk.

I have a file that has multiple lines on it and I need to read the file 1 at a time and then count the fields and field separators and then store those numbers in variables. I then need to delete the first 5 fields and the blank spaces.

example:
45 21 * * * run_cron /temp "daily_files.ksh"

I want to read the file that has this line and then write it to a new file with a line that looks like this:
run_cron /temp "daily_files.ksh"

The problem is that the the first 5 fields (which is what I really want to get rid of) are not the same for each line I am reading.

Any help is much appreciated. Thanks
