hi,
if i understand i can t use an exterior variable in a awk query?
if i wan to use the second parameter of my shell script ($2) in my awk query, is it possible?
for example i want to use the length of the second parameter:
echo $2| awk '{print length($1)}' | ...
i want to use the length to read the character in that position
code
'
echo "az" | awk '{print length($1)}'

and
echo "h.ello" | awk -F "." ' {print $( the value of the previuos query )}'

how can i execute the two queries in a 1 awk query?

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
