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

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  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, 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  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
