That's because the regex pattern doesn't match the data in your file:

Code:
$ 
$ cat test.txt
CONTACT PEOPLE:first_name1.last_name1,first_name2.last_name2,first_name3.last_name3
$ 
$ awk '/^CONTACT PEOPLE:(?:[^\.]*?\.[^\.]*)+/' test.txt
$ 
$

The regex shown below matches the line; not sure if that's what you are looking for:

Code:
$ 
$ awk '/^CONTACT PEOPLE:([^\.]*?\.[^\.]*)+/' test.txt
CONTACT PEOPLE:first_name1.last_name1,first_name2.last_name2,first_name3.last_name3
$

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
