Search the shell variable inside awk

Hai,

I need to search a variable inside a file using awk in AIX.
for ex:
file.txt
one
two
three
four
five

i need to get the lines with two
awk '/two/ {print}' file.txt
But i need to change the two as a variable since it would be changed on runtime..i tried like below..nothing give me the result
Code:
awk -v a=two '/a/ {print}' file.txt

awk -v a=two '/'$a'/ {print}' file.txt

Please advise

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
