Hi all,

Need to solve this problem
file1.txt
Code:
0912804166|RR
0912804171|YY

file2.txt
Code:
0912804175|AXE|510100475741082
0912804166|NODE|0

I need to add event on file1.txt if column 1 in file1.txt is also found in file2.txt, the event is 1, but in contrary if column 1 in file1.txt is not found in file2.txt then the event added to the third column with 0

my expected output
Code:
0912804166|RR|1
0912804171|YY|0

I did this
Code:
awk -F'|' 'NR==FNR {h[$1] = $2; next} {FS=OFS="|";print $0,h[$1]}' file2.txt file1.txt | awk-F'|' '{if($3>0) print $0,"1"}{print $0,0}'

You were aiming in the right direction. Try
Code:
awk -F'|' 'NR==FNR {h[$1]=1; next} {print $0, h[$1]+0}' OFS="|" file2 file1
0912804166|RR|1
0912804171|YY|0

?
