I gave this file 

 a deiauk Biking US 200 G
 b kespaul 202 A
 c deiauk NY 222 5 Z

And I want to mach exact string 200 using `awk`
so my resul should be

 a deiauk Biking US 200 G
Here's my code

 awk -F ' ' '{if($(NF-1) ~ /200/){a[$1]++}}END{for (var in a){print a[var] " " var " " $(NF-1)}}' file.txt
But after that I got all lines
