I TRIED
awk 'FNR==NR {a[$2] = $0; next }{ if($1 in a) {p=$1;$1="";print a[p],$0}}' File1 File2
But didnt work.
Basically I want to get the details from FILE 1 and compare with FILE2 (master list) .
Example :
A1 in FILE2 was not available in FILE1 , so in output file we have “-“ for 1st three fields and rest from FILE2 . Now, we have A11 and we got the detail in FILE1. So we write details of A11 from both File 1 & 2
