I understand now, I was using everything on a script but not using the ; separator:

This is the script:
Code:
 
 
del 1not2.txt
del 2not1.txt
gawk "{  _0 = tolower($0);  if (NR == FNR)    A[_0];  else     B[_0]  }END{for(x in A){if(!(x in B))print x>\"1not2.txt\"}for(x in B){if(!(x in A))print x>\"2not1.txt\"}}" x1 x2
type 1not2.txt
type 2not1.txt

And it's working perfectly,
Thank you very much Radoulov!!Smilie

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
