Good! The cut version is approximately 3 times faster than split version, and even that one is significantly faster than what I came up with (+1). BTW, you seem to have an extra print s, c; in the cut version

The add and divide method can easily give false positives. eg. 3 lines of a file may have a column with 8+ 9+10=27, which gives the same result as 3 lines containing 9+9+9=27..

How big is your big file? Is it so big that manipulating it in an array will use up all your free memory?

comment Grep all string which do not starts with number(s)
By default, grep uses basic regular expressions. This means that your ? is being treated as a literal question-mark. Either escape the question-mark \?, or use the -E option for extended regular expressions, in which case ? is a pattern character.
