How to pick values from column based on key values by usin AWK
Dear Guyz
I have 2 different input files like this. I would like to pick the values or letters from the inputfile2 based on inputfile1 keys (A,F,N,X,Z).
I have done similar task by using awk but in that case the inputfiles are similar like in inputfile2 (all keys in 1st column and values in second column) by using the following.
Quote:
awk 'NR==FNR{_[$1]=$1;next}$1 in _{print _[$1],$0}' INPUT1.txt INPUT2.txt
But in this case inputfile1 is different , the keys are just not in single column but also in other columns.
Could you please help me on this.
Inputfile1
A tab F tab N
D
X tab Z
Inputfile2
A tab 1200
B tab 1000
D tab 3000
F tab AHAHA
G tab XXXXX
N tab YYYYY
X tab EEEEE
Z tab GGGG
I would like to join the the values or letters based on keys in 1st input file1
(A,F,N,D,X,Z) like the following
Output
A \t 1200 \t
F \t AHAHA \t
N \t YYYYY
D \t 3000
X \t EEEEE
Z \t GGGG
