Hi Hans Mackowiak and Shah,

Thanks for your quick reply.

I am executed your code. its giving string /dev/sda4.

its really use full for me.

just  i want to know onemore logic for

1. i dont  know how many character will come after /dev like it may come
/dev/sda4 , /dev/sda1256 or /dev/sdaERT7890. But my aim is to extract
the that word from /dev to end of that word like   "/dev/sda4" ,
"/dev/sda1256" , "/dev/sdaERT7890". for this what logic i need to add
after /dev in below of your logics


   stv = st.gsub("/dev/?")
   string.match(/[\/\w]+/)[0]#=> "/dev/?"


Random string like

string = "/dev/sda4             45225016   3702464  39225208   9% /"
string = "/dev/sda1256             45225016   3702464  39225208   9% /"
string = "/dev/sdaERT7890             45225016   3702464  39225208   9%
/"
string = "/dev/sda4sdfsd             45225016   3702464  39225208   9%
/"
string = "/dev/sda4fsdfs             45225016   3702464  39225208   9%
/"


form above string i need to extract   /dev/sda4 , /dev/sda1256,
/dev/sdaERT7890 , /dev/sda4sdfsd  and /dev/sda4fsdfs


please suggest your logic


Regards
Kotin
