thank you for you input.
i tried awk '!$1{$2+=1}1', however it gives me a bunch of errors. problem is that can not decipher the syntax of this awk expression for successful debugging. would you mind clarifying?

paste num.txt num2.txt | awk '!$1{$2+=1}1'

output in terminal:
paste num.txt num2.txt | awk 'num2.txt1{$2+=1}1'
awk: syntax error at source line 1
context is
>>> num2 <<< .txt1{$2+=1}1
awk: bailing out at source line 1


thank you!

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
