AWK: How to increment values in a column by one

In a previous question I asked how to decrement the value of all entries in a column by 1

The (correct) answer was awk '{ $7--; print $0 }', where $7 means the 7th column

What would an analogous answer for INCREMENTING column v开发者_开发技巧alues be?

Thanks so much

Use ++ instead of --.
