Hello flamer,

Welcome to UNIX and LINUX forums hope you will enjoy learning and sharing knowledge here. Since you have not shown any samples so couldn't test following code. Could you please try following and let me know if this helps you.
Code:
awk 'match($0,/[a-zA-Z]+@[a-zA-Z]+\.com/){print substr($0,RSTART,RLENGTH)}'  Input_file

NOTE: on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk , /usr/xpg6/bin/awk , or nawk.

Thanks,
R. Singh

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
