Hi,
Initially, I think of using this command too. But, the motivation is to find the match of number in these files and extract the first field. If the first field is the "search string" it would print the filename.
In other words, I have to get two information. For example:-
Input file (a.txt) has:-
@@@ 10 testingtestingtestingtesting
Initially, i need to grep the 10 in any *.txt and then get the first field. If first field is @@@@, i would print the filename.
If using the above command, I could only get the filename when I need to match only one type of information.
Any suggestion?
Thanks.
Rgrds,
Jason

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.
