It appears that you have an alias or other implementation of 'grep', and 
that this is not a bug in GNU 'grep' per se. If you are using a shell 
like 'bash', try these two shell commands to see which 'grep' you are 
actually using.

type grep
which grep

Hi Paul,
         When I use type grep I get following :

$ type grep

grep is a function

grep ()

{

    /usr/bin/grep --color=auto $*

}

          When I use which grep I get following:

$which grep

/usr/bin/grep

That function is erroneous due to the use of unquoted $*.
Use this instead, which fixes that, and also works when the executable
grep is not in /usr/bin:

grep() { env grep --color=auto "$@"; }

Hi Jim,
         After following your comment, the error (I am not sure now if I
could call it an error) has gone. So you were right, it was due to the way
I was handling positional parameters in my .profile file.

Sol: changing from

grep ()

{

    /usr/bin/grep --color=auto $*

}


to

grep ()

{

    /usr/bin/grep --color=auto "$@"

}
solved it. (Not sure ';' is required here )
