Finding a specific pattern from thousands of files ????

Hi All,

I want to find a specific pattern from approximately 400000 files on solaris platform. Its very heavy for me to grep that pattern to each file individually.

Can anybody suggest me some way to search for specific pattern (alpha numeric) from these forty thousand files. Please note that out of 40000 files only few files has this specific pattern.

I would really be greatful. This really can make my work easy.

Thanks,
Aru

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME
bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression SYNOPSIS
bzgrep [ grep_options ] [ -e ] pattern filename... bzegrep [ egrep_options ] [ -e ] pattern filename... bzfgrep [ fgrep_options ] [ -e ] pattern filename... DESCRIPTION
Bzgrep is used to invoke the grep on bzip2-compressed files. All 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 bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, bzgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep bzgrep string files for csh: (setenv GREP fgrep; bzgrep string files) AUTHOR
