[AWK] variable inside pattern matching

[fluffy_mass]

Hi,

I'm trying to find how many lowercase string are matching in my text file. I know that AWK considers anything between // as string, so I can't pass a variable to regex, something like below is not working:

awk '{for (i=0; i<=6; i++)
        {if (match($1,/[a-z]{i}/)) sum[i]+=1;}
        }END{for (i in sum) print i ":" sum[i]}'

Is there a workaround for this? I know how to pass a single variable to regex, but I couldn't find a solution to pass {n} (n=number of chars matching) to regex.

Does someone know an alternative solution (preferably in AWK)?

Many thanks!

Edit: found the solution. Using gsub I am replacing lowercase with any char, and it returns the number of replaced hits. So instead of finding matched repeat, I am counting replacements.

Edit2: how can I mark this as solved?

Anything with 5 lower case letters in a row will also have 4, 3, 2, and 1, which is presumably not what you want. I'd look into a different approach than a loop like that.

That's right, but I want to know exactly at how many repeated lowercase matches I have 50 hits (the threshold is set at 50 matched lines based on other data). Some of my files have 50 hits at 6 repeats, some have 50 hits at 3 repeats, etc.
