Question

I want to use regex to do a grouping with a search and replacement string technique for EDI purposes and can i force the replacment to be within a certain size constraint in my EDI output?

INPUT:

01234567890123456789012345678901234567890123456789012345678901234567890123456789
EINSTEIN            ALBERT              165

Regex Unnamed Grouping Search:

(.*{20})(.*{20})(.*{20})

Regex Grouping Replace:

First:\2Last:\1IQ:\3

Output:

01234567890123456789012345678901234567890123456789012345678901234567890123456789
First:ALB Last:EIN IQ:165

Answer 1

You don’t seem to specify the tool you want to use (or I didn’t get it) but this may give you some clues:

$ echo 'EINSTEIN            ALBERT              165' |\
> sed -r 's/(.{3}).{17}(.{3}).{17}(.*)/First:\2 Last:\1 IQ:\3/'
First:ALB Last:EIN IQ:165
