one more request
Thanks a lot to rdcwayx and drewk

sending the same file two times was a smart idea

but what if i have some thing like this a string attached to the key word
Code:
apple    abc    cat    wegsdfg
in    def    rat    wrtyery
out    gasdf    sky    ertyenr
cat    asdfas    pen    etynu
rat    asdf    ball    dyunr
sky    asdf    cpu    wtyvshb
pen    asdfwr    linux    stryehbr
ball    wert    unix    sbysdfhb
cpu    wertj    paper    srtbvh
linux    erdeh    phone    shvgfhhj
unix    eryy 
paper    eryd 
phone    12345 
phone    34567 
paper    25347 
unix    4574576 
cpu    3745634

and i wanted a similar out put like before but along with the strings

Thanks
