how to deleting except the patern in a file

Hello respected members,

I have a file wich has several fields separated by space. I want to remove all the fields which are not the client_name.
I mean the field which are not "pfizer","csx" and "mafoi". And the deletion action will be taken place from the 3rd field(including the third field).


my input file looks like

Code:
quality hardware csx pfizet honda kiuty
hardware quality pfizer name 
newyork quality mafoi pfizer  working csx


my output shoul be like this:

Code:
quality hardware csx pfizet 
hardware quality pfizer  
newyork quality mafoi pfizer  csx

can it will be done by awk.

thanks in advance

pnmmontage(1)                                                 General Commands Manual                                                pnmmontage(1)

NAME
pnmmontage - create a montage of portable anymaps SYNOPSIS
pnmmontage [-?|-help] [-header=headerfile] [-quality=n] [-prefix=prefix] [-0|-1|-2|...|-9] pnmfile... DESCRIPTION
Packs images of differing sizes into a minimum-area composite image, optionally producing a C header file with the locations of the subim- ages within the composite image. OPTIONS
-?, -help Displays a (very) short usage message. -header Tells pnmmontage to write a C header file of the locations of the original images within the packed image. Each original image gen- erates four #defines within the packed file: xxxX, xxxY, xxxSZX, and xxxSZY, where xxx is the name of the file, converted to all uppercase. The #defines OVERALLX and OVERALLY are also produced, specifying the total size of the montage image. -prefix Tells pnmmontage to use the specified prefix on all of the #defines it generates. -quality Before attempting to place the subimages, pnmmontage will calculate a minimum possible area for the montage; this is either the total of the areas of all the subimages, or the width of the widest subimage times the height of the tallest subimage, whichever is greater. pnmmontage then initiates a problem-space search to find the best packing; if it finds a solution that is (at least) as good as the minimum area times the quality as a percent, it will break out of the search. Thus, -q 100 will find the best possible solution; however, it may take a very long time to do so. The default is -q 200. -0, -1, ... -9 These options control the quality at a higher level than -q; -0 is the worst quality (literally pick the first solution found), while -9 is the best quality (perform an exhaustive search of problem space for the absolute best packing). The higher the number, the slower the computation. The default is -5. NOTES
Using -9 is excessively slow on all but the smallest image sets. If the anymaps differ in maxvals, then pnmmontage will pick the smallest maxval which is evenly divisible by each of the maxvals of the original images. SEE ALSO
