Match digits in [g]awk

Question

I\'m stumped! Trying to write an awk regex to match a string against 11 digits.

I\'ve tried:

if (var ~ /^[0-9]{11}$/ )
if (var ~ /^([0-9]){11}$/ )
if (va         


        

Answer 1

You described your problem, but didn't tell us your awk version. It is an important information.

but this may work for your case:

if (var ~ /^[0-9]+$/ && length(var)==11)

If we know the version, there could be simpler solution.
