Red Hat and Cygwin

I usually use RedHat but I am now using Cygwin. I tried gawk and I got the same result:

Quote:
$ gawk '/\> ID/{x=$0 ; next}{if ( length >= 10 && length < 20 ){a[$0]++;b[x]=$0}}END {for (i in a) for (j in b) if(i==b[j]){print j "\t freq " a[i]"\n" i;break;}}' Test.txt
freq 2

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
