Populate Column Value Using AWK
Hi All,

I am trying to find out awk one liner for the following requirement but failed in doing that.

HTML Code:
I have two files. 

Content of first file:

file1.txt      SUCCESS          A  
file2.txt      SUCCESS          B
file3.txt      SUCCESS          A
file4.txt      FAIL                A
file5.txt      SUCCESS          C
file6.txt      FAIL                B


Content of second file:

A        DEL
B        TEL
C        BSMS
I wish to populate the fourth column of first file based on the values mentioned in secodn file.

Your help is highly appreciated

Thanks and Regards
Angshuman

Code:
awk 'NR==FNR{a[$1]=$2; next} {for(x in a){if($3==x){print $0,a[x]}}}' file2 file1

Knowing nothing about your OS nor awk- version, this might work
Code:
awk 'NR==FNR{a[$1]=$2;next}  {print $1,$2,$3,a[$3]}' OFS="\t" file2 file1

Adapt OFS after your fancy.

(You may replace print $1..$3 by balajesuri's print $0 if you don't want OFS to be the same all over the line)

awk 'NR==FNR{a[$1]=$2;next}(a[$3]){$4=a[$3];print}' file2 file1

Don't you think you are preventing entire lines from file1 from being printed if the 3rd field is not in the look-up file?

@elixir: ($4=a[$3])||1 would be equivalent to {$4=a[$3]}1, no?
