Well, if the 7th (I think you meant 7th) field is always the last field, then
why not use grep?
darkhawk:~/> grep ':0$' foo
That is, if you want the whole line; the grep output can always be piped into
awk to pull out specific columns. You can also search on other columns:
grep ':string:[^:]*$' # The second to last column
grep '^string:' # The first column
grep '^[^:]*:string:' # The second column
man 1 grep for more information.
