searching for a specific Pattern 1

[UCF87]

I have the following input:

AAAA011
BBBB022
CCCC
EEEE222
FFFFF333
~

I want to create an exception report to find CCCC, without knowing what CCCC is.

I have tried:
awk '{if($1~/.... */) print $0}' input > output

Thank you in advance

let me see: you want to find something you don't know what it is? That's a bit more chanllenging than awk can handle!

Do you want to get lines with characters ONLY maybe?
Pls provide sample input and sample output.

Try this:

awk '/^....    */' input > output

Hope This Help

The ^ for begining of line still does not capture and print CCCC only. Maybe AWK does not work well with spaces?
I want the output to show all occurrences of any lines without numbers.

nawk '!/[0-9]+/'
