Thanks Keelba, from your program, I got it into one liner:
(echo "1.txt";echo "2.txt") | xargs zgrep -n STRING | awk -F: '{printf "%s %s", $1" -", $2 "\n"}'
Later:
xargs zgrep -n STRING | awk -F: '{printf "%s %s", $1" -", $2 "\n"}'
I placed the above line in a file: vv-grep
Then, I can run this script neatly as:
(echo "1.txt";echo "2.txt") | ./vv-grep
The final thing which I want to enhance here is only for the input string to be searched for, so that the program can be executed like:
(echo "1.txt";echo "2.txt") | ./vv-grep STRING
I am trying to find out how I can get input in command line parameter to the script.
Thanks for the great help. I was able to understand your suggestion and could mould it in the way I wanted.
It will be great if you could tell me if you know as how to get the input from comand line parameter to the script.

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
