How to grep nth word in line?
my input file content is like this
Code:
GEFITINIB 403 14 -4.786873 -4.786873 -1.990111 0.000000 0.000000 -1.146266 -39.955912 483

my output should be line whose second word is 405
Code:
VANDETANIB 405 21 -4.737541 -4.737541 -2.670195 -0.006006 0.000000 -0.285579 -40.793145 472

If I use grep command
Code:
grep 405 file

it gives three lines
Code:
VANDETANIB 405 21 -4.737541 -4.737541 -2.670195 -0.006006 0.000000 -0.285579 -40.793145 472
Neratinib 40 19 -4.680369 -4.680369 -1.618439 -0.196470 0.000000 -0.001702 -51.090346 405
1m17-co 409 1 -4.634879 -4.634879 -1.465411 -0.430470 0.000000 -0.900950 -38.233987 405

but I want only the line whose second word is 405

Thanks in advance

wml::std::box

wml::std::box(3)						     EN Tools							  wml::std::box(3)

NAME

       wml::std::box - Easily Create Rectangular Box

SYNOPSIS

	#use wml::std::box

	<box [attributes]>
	...
	</box>

DESCRIPTION

       The "<box>" container tag puts its body into a nice rectangular box which itself is build via a HTML "<table>" construct.

ATTRIBUTES

       "header"
	   This attribute switches between two totally different box variants.	When it is present, a headlined box is created by the use of one
	   single table but with space GIFs. When this attribute is missing a standard box is created by the use of two nested tables but without
	   any space GIFs.

       "bgcolor"
	   This sets the background color of the box.

       "fgcolor"
	   This sets the foreground (text) color of the box.

       "bdcolor"
	   This sets the color for the border of the box. The effect of this attribute is the automatic generation of a nested table construct to
	   achieve the optical effect.

       "bdspace"
	   This sets the space between the border and the body of the box in pixels.  Default is 4 pixel.

       "bdwidth"
	   This sets the border width in pixels. Default is 1 pixel.

       "width"
	   This sets the total table width in pixels. Default is no specific width for the standard box and 300 pixels for the headlined box
	   (because the headlined variant needs to know a fixed size to create the GIFs accordingly).

       "summary"
	   Add a description of this table.  This attribute is recommended in HTML 4.0.

EXAMPLE

	<box bdcolor="#000000" bdwidth=1 bdspace=10
	     bgcolor="#ffffff" fgcolor="#000000">
	Foo Bar Quux
	</box>

	<box header="Foo Bar Quux Header"
	     bdcolor="#000000" bdwidth=1 bdspace=10
	     bgcolor="#ffffff" fgcolor="#000000">
	Foo Bar Quux
	</box>
