Fantastic malcomex999

But please clarify me few things in your code.

a) what does 'x' signify here? I am not seeing it is declared/initialized elsewhere
b) How can I use the the pattern, single quotes inside the gsub() instead of declaring a variable separately for the purpose of it?
c) One of the element in the array is having '11', but we just have the character class pattern /[0-9]/ to match this '11' instead of the multi-pattern /[0-9]*/. How this works for the multiple instances of the same pattern (i.e) digit?
d) Finally, if I want to remove the "if" statement and to make it simple with just $i ~ /[0-9], how to re-arrange the syntax?

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
