Hello.
I have a huge text file with strings with : delimited values as -
1000:2000:454758:676869:bad:bad:546474:... and so on
I want to pick up (let's say) the 8th and 12th values and replace them with a
string if they are not valid numbers. What is the most efficent way? This is a large file, I want to do it most optimized.
I can use split(regex, n).
TIA
