but in my case it did not work. I ran it on the following para from wiki abt grep
Quote:
There are countless implementations and derivatives of grep available for many operating systems. Early variants of grep included egrep and fgrep. egrep applies an extended regular expression syntax that was added to Unix after Ken Thompson's original regular expression implementation. fgrep searches for any of a list of fixed strings using the Aho.Corasick string matching algorithm. These variants of grep persist in most modern grep implementations as command-line switches (and standardized as -E and -F in POSIX[3]). In such combined implementations, grep may also behave differently depending on the name by which it is invoked, allowing fgrep, egrep, and grep to be links to the same program.
Other commands contain the word "grep" to indicate that they search (usually for regular expression matches). The pgrep utility, for instance, displays the processes whose names match a given regular expression.
In Perl, grep is the name of the built-in function that finds elements in a list that satisfy a certain property. This higher-order function is typically named filter in functional programming languages.
pcregrep is an implementation of grep that uses Perl regular expression syntax.
Ports of grep (within Cygwin and GnuWin32, for example) also run under Microsoft Windows. Some versions of Windows feature the similar qgrep command

gzgrep
GZGREP(1) General Commands Manual GZGREP(1)NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression
SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
gzgrep 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 gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep gzgrep string files
for csh: (setenv GREP fgrep; gzgrep string files)
