i don't know why you are using sed command.

you mention that data is already exist.
then you can use awk command like this.
Code:
first_val=`cat filename|head -1|awk -F":" '{print $1}'`
sec_val=`cat filename|head -1|awk -F":" '{print $2}'`
thrd_val=`cat filename|head -1|awk -F":" '{print $3}'`

if you want for a file then use head $variable in loop.
if you have any doubt please send a mail.

regards
rajesh

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
